Psalm 19:12

Who can understand his errors? cleanse thou me from secret faults.

EXPOSITORY (ENGLISH BIBLE)

Ellicott's Commentary for English Readers

(12) His eulogium on the Law was not Pharisaic or formal, for the poet instantly gives expression to his sense of his own inability to keep it. If before we were reminded of St. Paul’s, “The law is holy, and the commandment holy, and just, and good,” (Romans 7:12), his own spiritual experience, contained in the same chapter, is here recalled: “For the good that I would I do not: but the evil that I would not, that I do.”

Who can understand.—In the original the abruptness of the question is very marked and significant. Errors who marks? From unconscious ones clear me, i.e., pronounce me innocent, not cleanse, as in Authorised Version.

Psalms

SECRET FAULTS

Psalm 19:12.

The contemplation of the ‘perfect law, enlightening the eyes,’ sends the Psalmist to his knees. He is appalled by his own shortcomings, and feels that, beside all those of which he is aware, there is a region, as yet unilluminated by that law, where evil things nestle and breed.

The Jewish ritual drew a broad distinction between inadvertent-whether involuntary or ignorant-and deliberate sins; providing atonement for the former, not for the latter. The word in my text rendered ‘errors’ is closely connected with that which in the Levitical system designates the former class of transgressions; and the connection between the two clauses of the text, as well as that with the subsequent verse, distinctly shows that the ‘secret faults’ of the one clause are substantially synonymous with the ‘errors’ of the other.

They are, then, not sins hidden from men, whether because they have been done quietly in a corner, and remain undetected, or because they have only been in thought, never passing into act. Both of these pages are dark in every man’s memory. Who is there that could reveal himself to men? who is there that could bear the sight of a naked soul? But the Psalmist is thinking of a still more solemn fact, that, beyond the range of conscience and consciousness, there are evils in us all. It may do us good to ponder his discovery that he had undiscovered sins, and to take for ours his prayer, ‘Cleanse Thou me from secret faults.’

I. So I ask you to look with me, briefly, first, at the solemn fact here, that there are in every man sins of which the doer is unaware.

It is with our characters as with our faces. Few of us are familiar with our own appearance, and most of us, if we have looked at our portraits, have felt a little shock of surprise, and been ready to say to ourselves, ‘Well! I did not know that I looked like that!’ And the bulk even of good men are almost as much strangers to their inward physiognomy as to their outward. They see themselves in their looking-glasses every morning, although they ‘go away and forget what manner of men’ they were. But they do not see their true selves in the same fashion in any other mirror. It is the very characteristic of all evil that it has a strange power of deceiving a man as to its real character; like the cuttle-fish, that squirts out a cloud of ink and so escapes in the darkness and the dirt. The more a man goes wrong the less he knows it. Conscience is loudest when it is least needed, and most silent when most required.

Then, besides that, there is a great part of every one’s life which is mechanical, instinctive, and all but involuntary. Habits and emotions and passing impulses very seldom come into men’s consciousness, and an enormously large proportion of everybody’s life is done with the minimum of attention, and is as little remembered as it is observed.

Then, besides that, conscience wants educating. You see that on a large scale, for instance, in the history of the slow progress which Christian principle has made in leavening the world’s thinkings. It took eighteen centuries to teach the Church that slavery was unchristian. The Church has not yet learned that war is unchristian, and it is only beginning to surmise that possibly Christian principle may have something to say in social questions, and in the determination, for example, of the relations of capital and labour, and of wealth and poverty. The very same slowness of apprehension and gradual growth in the education of conscience, and in the perception of the application of Christian principles to duty, applies to the individual as to the Church.

Then, besides that, we are all biassed in our own favour, and what, when another man says it, is ‘flat blasphemy,’ we think, when we say it, is only ‘a choleric word.’ We have fine names for our own vices, and ugly ones for the very same vices in other people. David will flare up into generous and sincere indignation about the man that stole the poor man’s ewe lamb, but he has not the ghost of a notion that he has been doing the very same thing himself. And so we bribe our consciences as well as neglect them, and they need to be educated.

Thus, down below every life there lies a great dim region of habits and impulses and fleeting emotions, into which it is the rarest thing for a man to go with a candle in his hand to see what it is like.

But I can imagine a man saying, ‘Well, if I do not know that I am doing wrong, how can it be a sin?’ In answer to that, I would say that, thank God! ignorance diminishes criminality, but ignorance does not alter the nature of the deed. Take a simple illustration. Here is a man who, all unconsciously to himself, is allowing worldly prosperity to sap his Christian character. He does not know that the great current of his life has been turned aside, as it were, by that sluice, and is taken to drive the wheels of his mill, and that there is only a miserable little trickle coming down the river bed. Is he any less guilty because he does not know? Is he not the more so, because he might and would have known if he had thought and felt right? Or, here is another man who has the habit of letting his temper get the better of him. He calls it ‘stern adherence to principle,’ or ‘righteous indignation’; and he thinks himself very badly used when other people ‘drive him’ so often into a temper. Other people know, and he might know, if he would be honest with himself, that, for all his fine names, it is nothing else than passion. Is he any the less guilty because of his ignorance? It is plain enough that, whilst ignorance, if it is absolute and inevitable, does diminish criminality to the vanishing point, the ignorance of our own faults which most of us display is neither absolute nor inevitable; and therefore, though it may, thank God! diminish, it does not destroy our guilt. ‘She wipeth her mouth and saith, I have done no harm’: was she, therefore, chaste and pure? In all our hearts there are many vermin lurking beneath the stones, and they are none the less poisonous because they live and multiply in the dark. ‘I know nothing against myself, yet am I not hereby justified. But he that judgeth me is the Lord.’

II. Now, secondly, let me ask you to look at the special perilousness of these hidden faults.

As with a blight upon a rose-tree, the little green creatures lurk on the underside of the leaves, and in all the folds of the buds, and because unseen, they increase with alarming rapidity. The very fact that we have faults in our characters, which everybody sees but ourselves, makes it certain that they will grow unchecked, and so will prove terribly perilous. The small things of life are the great things of life. For a man’s character is made up of them, and of their results, striking inwards upon himself. A wine-glassful of water with one drop of mud in it may not be much obscured, but if you come to multiply it into a lakeful, you will have muddy waves that reflect no heavens, and show no gleaming stars.

These secret faults are like a fungus that has grown in a wine-cask, whose presence nobody suspected. It sucks up all the generous liquor to feed its own filthiness, and when the staves are broken, there is no wine left, nothing but the foul growth. Many a Christian man and woman has the whole Christian life arrested, and all but annihilated, by the unsuspected influence of a secret sin. I do not believe it would be exaggeration to say that, for one man who has made shipwreck of his faith and lost his peace by reason of some gross transgression, there are twenty who have fallen into the same condition by reason of the multitude of small ones. ‘He that despiseth little things shall fall by little and little’; and whilst the deeds which the Ten Commandments rebuke are damning to a Christian character, still more perilous, because unseen, and permitted to grow without check or restraint, are these unconscious sins. ‘Happy is he that condemneth not himself in that thing which he alloweth.’

III. Notice the discipline, or practical issues, to which such considerations should lead.

To begin with, they ought to take down our self-complacency, if we have any, and to make us feel that, after all, our characters are very poor things. If men praise us, let us try to remember what it will be good for us to remember, too, when we are tempted to praise ourselves-the underworld of darkness which each of us carries about within us.

Further, let me press upon you two practical points. This whole set of contemplations should make us practise a very rigid and close self-inspection. There will always be much that will escape our observation-we shall gradually grow to know more and more of it-but there can be no excuse for that which I fear is a terribly common characteristic of the professing Christianity of this day-the all but entire absence of close inspection of one’s own character and conduct. I know very well that it is not a wholesome thing for a man to be always poking in his own feelings and emotions. I know also that, in a former generation, there was far too much introspection, instead of looking to Jesus Christ and forgetting self. I do not believe that self-examination, directed to the discovery of reasons for trusting the sincerity of my own faith, is a good thing. But I do believe that, without the practice of careful weighing of ourselves, there will be very little growth in anything that is noble and good.

The old Greeks used to preach, ‘Know thyself.’ It was a high behest, and very often a very vain-glorious one. A man’s best means of knowing what he is, is to take stock of what he does. If you will put your conduct through the sieve, you will come to a pretty good understanding of your character. ‘He that hath no rule over his own spirit is like a city broken down, without walls,’ into which all enemies can leap unhindered, and out from which all things that will may pass. Do you set guards at the gates and watch yourselves with all carefulness.

Then, again, I would say we must try to diminish as much as possible the mere instinctive and habitual and mechanical part of our lives, and to bring, as far as we can, every action under the conscious dominion of principle. The less we live by impulse, and the more we live by intelligent reflection, the better it will be for us. The more we can get habit on the side of goodness, the better; but the more we break up our habits, and make each individual action the result of a special volition of the spirit guided by reason and conscience, the better for us all.

Then, again, I would say, set yourselves to educate your consciences. They need that. One of the surest ways of making conscience more sensitive is always to consult it and always to obey it. If you neglect it, and let it prophesy to the wind, it will stop speaking before long. Herod could not get a word out of Christ when he ‘asked Him many questions’ because for years he had not cared to hear His voice. And conscience, like the Lord of conscience, will hold its peace after men have neglected its speech. You can pull the clapper out of the bell upon the rock, and then, though the waves may dash, there will not be a sound, and the vessel will drive straight on to the black teeth that are waiting for it. Educate your conscience by obeying it, and by getting into the habit of bringing everything to its bar.

And, still further, compare yourselves constantly with your model. Do as the art students do in a gallery, take your poor daub right into the presence of the masterpiece, and go over it line by line and tint by tint. Get near Jesus Christ that you may learn your duty from Him, and you will find out many of the secret sins.

And, lastly, let us ask God to cleanse us.

My text, as translated in the Revised Version, says, ‘Clear Thou me from secret faults.’ And there is present in that word, if not exclusively, at least predominantly, the idea of a judicial acquittal, so that the thought of the first clause of this verse seems rather to be that of pronouncing guiltless, or forgiving, than that of delivering from the power of. But both, no doubt, are included in the idea, as both, in fact, come from the same source and in response to the same cry.

And so we may be sure that, though our eye does not go down into the dark depths, God’s eye goes, and that where He looks He looks to pardon, if we come to Him through Jesus Christ our Lord.

He will deliver us from the power of these secret faults, giving to us that divine Spirit which is ‘the candle of the Lord,’ to search us, and to convince of our sins, and to drag our evil into the light; and giving us the help without which we can never overcome. The only way for us to be delivered from the dominion of our unconscious faults is to increase the depth and closeness and constancy of our communion with Jesus Christ; and then they will drop away from us. Mosquitoes and malaria, the one unseen in their minuteness, and the other, ‘the pestilence that walketh in darkness,’ haunt the swamps. Go up on the hilltop, and neither of them are found. So if we live more and more on the high levels, in communion with our Master, there will be fewer and fewer of these unconscious sins buzzing and stinging and poisoning our lives, and more and more will His grace conquer and cleanse.

They will all be manifested some day. The time comes when He shall bring to light the hidden things and darkness and the counsels of men’s hearts. There will be surprises on both hands of the Judge. Some on the right, astonished, will say, ‘Lord, when saw we Thee?’ and some on the left, smitten to confusion and surprise, will say, ‘Lord, Lord, have we not prophesied in Thy name?’ Let us go to Him with the prayer, ‘Search me, O God! and try me; and see if there be any wicked way in me; and lead me in the way everlasting.’

Benson Commentary

Psalm 19:12. Who can understand his errors? — Upon the consideration of the perfect purity of God’s law, and the comparing of his spirit and conduct with it, he is led to make a penitent reflection upon his sins. Is the commandment thus holy, just, and good? then who can understand his errors? Lord, I am a sinful creature, and fall infinitely short of the demands of thy law, and am condemned by it. Cleanse thou me — Both by justification, or the pardon of my sins, through the blood of thy Son, which is in due time to be shed for me; and by sanctification through thy Holy Spirit, working in and with thy word, to the further renovation of my heart and life. For these are the two ways of cleansing sinners most frequently spoken of, both in the Old and New Testament: though the first may seem to be principally, if not only intended, because he speaks of his past sins, from which he could be cleansed no other way but my remission. From secret faults — From the guilt of such sins as were secret, either from others, such as none knows but God and my own conscience; or from myself, such as I never observed, or did not discern the evil of. Pardon my unknown sins, of which I never repented particularly, as I should have done.

Matthew Henry's Concise Commentary

19:11-14 God's word warns the wicked not to go on in his wicked way, and warns the righteous not to turn from his good way. There is a reward, not only after keeping, but in keeping God's commandments. Religion makes our comforts sweet, and our crosses easy, life truly valuable, and death itself truly desirable. David not only desired to be pardoned and cleansed from the sins he had discovered and confessed, but from those he had forgotten or overlooked. All discoveries of sin made to us by the law, should drive us to the throne of grace, there to pray. His dependence was the same with that of every Christian who says, Surely in the Lord Jesus have I righteousness and strength. No prayer can be acceptable before God which is not offered in the strength of our Redeemer or Divine Kinsman, through Him who took our nature upon him, that he might redeem us unto God, and restore the long-lost inheritance. May our hearts be much affected with the excellence of the word of God; and much affected with the evil of sin, and the danger we are in of it, and the danger we are in by it.

Barnes' Notes on the Bible

Who can understand his errors? - The word rendered errors is derived from a verb which means to wander, to go astray; then, to do wrong, to transgress. It refers here to wanderings, or departures from the law of God, and the question seems to have been asked in view of the purity, the strictness, and the extent of the law of God. In view of a law so pure, so holy, so strict in its demands, and so extended in its requirements - asserting jurisdiction over the thoughts, the words, and the whole life - who can recall the number of times that he has departed from such a law? A sentiment somewhat similar is found in Psalm 119:96, "I have seen an end of all perfection; thy commandment is exceeding broad." The language is such as every man who has any just sense of the nature and the requirements of the law, and a just view of his own life, must use in reference to himself. The reason why any man is elated with a conviction of his own goodness is that he has no just sense of the requirements of the law of God; and the more anyone studies that law, the more will he be convinced of the extent of his own depravity.

Hence, the importance of preaching the law, that sinners may be brought to conviction of sin; hence the importance of presenting it constantly before the mind of even the believer, that he may be kept from pride, and may walk humbly before God. And who is there that can understand his own errors? Who can number up the sins of a life? Who can make an estimate of the number of impure and unholy thoughts which, in the course of many years, have flitted through, or found a lodgment in the mind? Who can number up the words which have been spoken and should not have been spoken? Who can recall the forgotten sins and follies of a life - the sins of childhood, of youth, of riper years? There is but one Being in the universe that can do this. To Him all this is known. Nothing has escaped His observation; nothing has faded from His memory. Nothing can prevent His making a full disclosure of this if He shall choose to do so. It is in His power at any moment to overwhelm the soul with the recollection of all this guilt; it is in His power to cover us with confusion and shame at the revelation of the judgment-day. Our only hope - our only security - that He will not do this, is in His mercy; and that He may not do it, we should without delay seek His mercy, and pray that our sins may be so blotted out that they shall not be disclosed to us and to assembled worlds when we appear before Him.

Cleanse thou me from secret faults - The word here rendered secret means that which is hidden, covered, concealed. The reference is to those errors and faults which had been hidden from the eye of him who had committed them, as well as from the eye of the world. The sense is, that the law of God is so spiritual, and so pure, and so extended in its claims, that the author of the psalm felt that it must embrace many things which had been hidden even from his own view - errors and faults lying deep in the soul, and which had never been developed or expressed. From these, as well as from those sins which had been manifest to himself and to the world, he prayed that he might be cleansed. These are the things that pollute the soul; from these the soul must be cleansed, or it can never find permanent peace. A man who does not desire to be cleansed from all these "secret faults" cannot be a child of God; he who is a child of God will pray without ceasing that from these pollutions of the soul he may be made pure.

Jamieson-Fausset-Brown Bible Commentary

12-14. The clearer our view of the law, the more manifest are our sins. Still for its full effect we need divine grace to show us our faults, acquit us, restrain us from the practice, and free us from the power, of sin. Thus only can our conduct be blameless, and our words and thoughts acceptable to God.

The Treasury of David

12 Who can understand his errors? cleanse thou me from secret faults.

13 Keep back thy servant also from presumptuous sins; let them not have dominion over me: then shall I be upright, and I shall be innocent from the great transgression,

14 Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O Lord, my strength, and my redeemer.

Psalm 19:12

"Who can understand his errors?" A question which is its own answer. It rather requires a note of exclamation than of interrogation. By the law is the knowledge of sin, and in the presence of divine truth, the Psalmist marvels at the number and heinousness of his sins. He best knows himself who best knows the Word, but even such an one will be in a maze of wonder as to what he does not know, rather than on the mount of congratulation as to what he does know. We have heard of a comedy of errors, but to a good man this is more like a tragedy. Many books have a few lines of errata at the end, but our errata might well be as large as the volume if we could but have sense enough to see them. Augustine wrote in his older days a series of Retractations; ours might make a library if we had enough grace to be convinced of our mistakes and to confess them. "Cleanse thou me from secret faults." Thou canst mark in me faults entirely hidden from myself. It were hopeless to expect to see all my spots; therefore, O Lord, wash away in the atoning blood even those sins which my conscience has been unable to detect. Secret sins, like private conspirators, must be hunted out or they may do deadly mischief; it is well to be much in prayer concerning them. In the Lateran Council of the Church of Rome, a decree was passed that every true believer must confess his sins, all of them, once in a year to the priest, and they affixed to it this declaration, that there is no hope of pardon but in complying with that decree. What can equal the absurdity of such a decree as that? Do they suppose that they can tell their sins as easily as they can count their fingers? Why, if we could receive pardon for all our sins by telling every sin we have committed in one hour, there is not one of us who would be able to enter heaven, since, besides the sins that are known to us and that we may be able to confess, there are a vast mass of sins, which are as truly sins as those which we lament, but which are secret, and like the farmer's small samples which he brings to market, when he has left his granary full at home. We have but a very few sins which we can observe and detect, compared with those which are hidden from ourselves and unseen by our fellow-creatures.

Psalm 19:13

"Keep back thy servant also from presumptuous sins; let them not have dominion over me." - This earnest and humble prayer teaches us that saints may fall into the worst of sins unless restrained by grace, and that therefore they must watch and pray lest they enter into temptation. There is a natural proneness to sin in the best of men, and they must be held back as a horse is held back by the bit or they will run into it. Presumptuous sins are peculiarly dangerous. All sins are great sins, but yet some sins are greater than others. Every sin has in it the very venom of rebellion, and is full of the essential marrow of traitorous rejection of God; but there be some sins which have in them a greater development of the essential mischief of rebellion, and which wear upon their faces more of the brazen pride which defies the Most High. It is wrong to suppose that because all sins will condemn us, that therefore one sin is not greater than another. The fact is, that while all transgression is a greatly grievous and sinful thing, yet there are some transgressions which have a deeper shade of blackness, and a more double scarlet-dyed hue of criminality than others. The presumptuous sins of our text are the chief and worst of all sins; they rank head and foremost in the list of iniquities. It is remarkable that though an atonement was provided under the Jewish law for every kind of sin, there was this one exception: "But the soul that sinneth presumptuously shall have no atonement; it shall be cut off from the midst of my people." And now under the Christian dispensation, although in the sacrifice of our blessed Lord there is a great and precious atonement for presumptuous sins, whereby sinners who have erred in this manner are made clean, yet without doubt, presumptuous sinners, dying without pardon, must expect to receive a double portion of the wrath of God, and a more terrible portion of eternal punishment in the pit that is digged for the wicked. For this reason is David so anxious that he may never come under the reigning power of these giant evils. "Then shall I be upright, and I shall be innocent from the great transgression." He shudders at the thought of the unpardonable sin. Secret sin is a stepping stone to presumptuous sin, and that is the vestibule of "the sin which is unto death." He who is not wilful in his sin, will be in a fair way to be innocent so far as poor sinful man can be; but he who tempts the devil to tempt him is in a path which will lead him from bad to worse, and from the worse to the worst.

Psalm 19:14

"Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O Lord, my strength, and my Redeemer." A sweet prayer, and so spiritual that it is almost as commonly used in Christian worship as the apostolic benediction. Words of the mouth are mockery if the heart does not meditate; the shell is nothing without the kernel; but both together are useless unless accepted; and even if accepted by man, it is all vanity if not acceptable in the sight of God. We must in prayer view Jehovah as our strength enabling, and our Redeemer saving, or we shall not pray aright, and it is well to feel our personal interest so as to use the word my, or our prayers will be hindered. Our near Kinsman's name, our Goel or Redeemer, makes a blessed ending to the Psalm; it began with the heavens, but it ends with him whose glory fills heaven and earth. Blessed Kinsman, give us now to meditate acceptably upon thy most sweet love and tenderness.

Matthew Poole's Commentary

Who can understand? this may be here added, either,

1. As a further proof of the excellency and necessity of God’s law, because men’s errors are so many and hard to be discovered and prevented, that they indispensably need such a friend and counsellot as the law is, to give them the true knowledge of themselves and of their sins. Or,

2. As a just and sorrowful censure of himself, upon the consideration of the exact purity of God’s law, and the comparing of his life with it. Thy law, O Lord, is holy, and just, and good. But I am a poor sinful wretch, falling infinitely short of it, and condemned by it. Or,

3. As a signification of the insufficiency of God’s law, strictly so called, for the healing and saving of men’s souls, and of the necessity of further supplies of the gospel and grace of God; whereby the eyes of their minds may be enlightened to see that light which shines in God’s law, and their hearts may be renewed to yield universal obedience to it, for which therefore he prays in the following words. And withal, he implies that he did not expect that reward which he last mentioned as a just recompence to his obedience, which he confesseth to need a pardon more than to deserve a reward, but only as an effect of God’s grace and goodness.

His errors; either,

1. His sins of ignorance, of which this word is used, Leviticus 4:2,22,27 Ec 5:6. Or rather,

2. His sins in general, (which afterwards he divides into secret and presumptuous sins,) or all deviations from God’s law, which are thus called, 1 Samuel 26:21 Psalm 119:67,118 Heb 9:7 Jam 5:20. The sense is, I cannot comprehend the numbers, or the several kinds, or all the heinous aggravations of my sins.

Cleanse thou me; both by justification, or the pardon of my sins, through the blood of thy Son, which is to be shed for me; and by sanctification through thy Holy Spirit, co-working in and with thy word, to the further renovation of my heart and life for these are the two ways of cleansing sinners most frequently mentioned both in the Old and New Testament: though the first may seem to be principally, if not only, intended, because he speaks of his past sins, which could be cleansed no other way but by remission.

From secret faults, i.e. from the guilt of such sins as were secret, either,

1. From others; such as none knows but God and my own conscience: or,

2. From myself; such as I never observed, or did not discern the evil of. Pardon my unknown sins, of which I never repented particularly, as I should have done.

Gill's Exposition of the Entire Bible

Who can understand his errors?.... Sin is an error, a wandering out of the way of God, swerving from the rule of his word; and many mistakes are made by the people of God themselves; even so many that they cannot number them; they are more than the hairs of their head; they cannot understand, find out and express, neither their number, nor their evil nature, nor the many aggravating circumstances which attend them: this the psalmist said, upon a view of the large extent, glory, and excellency of the word of God; and upon comparing himself with it, in which, as in a glass, he saw how far short he came of it, and what a disagreement and want of conformity there was in him unto it; see Psalm 119:97; and he suggests, that though the word he had been describing was perfect, pure, and clean, he was not; nor could he expect any reward of debt, but merely of grace, for his observance of it; and that it was best, under a sense of sin, to have recourse, not to works of righteousness done by men; but to the grace and mercy of God in Christ, as follows:

cleanse thou me from secret faults; by which are meant not such sins as are done in secret, and are unknown to men; such as David's sin with Bathsheba, 2 Samuel 12:12; nor the inward motions of sin in the heart, to which none are privy but God, and a man's own soul; not but that each of these may be properly enough included in such a petition; but sins, which are unknown to a man himself are meant: there are some actions, which, though known when committed, are not known to be sinful ones; and there are some sins which are committed unadvisedly, and through carelessness, and pass unobserved; not only many vain and sinful thoughts pass to and fro uncontrolled, without being taken notice of; but many foolish and idle words are spoken, and many evil actions, through infirmity and inadvertency, are done, which, when a good man, at the close of a day, comes to reflect upon the things that have passed in it, are quite hidden from him, are unknown to him, being unobserved by him; wherefore such a petition is highly proper to be inserted in his address at the throne of grace: and which also supposes the person sensible of the defiling nature of sin, and of his own impotency to cleanse himself from it; and that God only can do it, who does it by the application of the blood of his Son, which cleanses from all sin; for this respects not regenerating and sanctifying grace, but pardoning grace; a manifestation of it, a view of acquittance from sin by Christ, and of freedom from obligation to punishment for it.

Geneva Study Bible

Who can understand his {l} errors? cleanse thou me from secret faults.

(l) Then there is no reward of duty, but of grace: for where sin is, there death is the reward.

12. More exactly:

Errors who can discern?

From hidden (faults) clear thou me.

Who can be aware of the manifold lapses of ignorance or inadvertence? Acquit me, do not hold me guilty in respect of them.

12–14. The contemplation of this holy law leads the Psalmist to express his personal need of preservation and guidance.

Pulpit Commentary

Verses 12-14. - A consideration of the Law cannot but raise the thought of transgression. Man "had not known sin but by the Law" (Romans 7:7), and he cannot contemplate the Law without being reminded of possible disobedience to it. The psalmist's thoughts are led in this direction, and he ends with an earnest prayer against "secret sins" (ver. 12), against "presumptuous sins" (ver. 13), and against sins of word and thought (ver. 14), addressed to "God his Strength [or, 'his Rock'] and his Redeemer." Verse 12. - Who can understand his errors? rather, who can discern (or, perceive) his errors? i.e. all of them. Who will not overlook some, try as he may to search out his heart? Cleanse thou me from secret faults. Those which are hidden from me, which I cannot discern. Psalm 19:12

Keil and Delitzsch Biblical Commentary on the Old Testament

(Heb.: 19:10-14) With הנּחמדים (for which, preferring a simple Sheb with the gutturals, Ben-Naphtali writes הנּחמּמדים) the poet sums up the characteristics enumerated; the article is summative, as in השּׁשּׁי at the close of the hexahemeron, Genesis 1:31. פּז is the finest purified gold, cf. 1 Kings 10:18 with 2 Chronicles 9:17. נפת צוּפים "the discharge (from נפת equals Arab. nft) of the honeycombs" is the virgin honey, i.e., the honey that flows of itself out of the cells. To be desired are the revealed words of God, to him who possesses them as an outward possession; and to him who has received them inwardly they are sweet. The poet, who is himself conscious of being a servant of God, and of striving to act as such, makes use of these words for the end for which they are revealed: he is נזהר, one who suffers himself to be enlightened, instructed, and warned by them. גּם belongs to נזהר (according to the usual arrangement of the words, e.g., Hosea 6:11), just as in Psalm 19:14 it belongs to חשׂך. He knows that בּשׁמרם (with a subjective suffix in an objective sense, cf. Proverbs 25:7, just as we may also say:) in their observance is, or is included, great reward. עקב is that which follows upon one's heels (עקב), or comes immediately after anything, and is used here of the result of conduct. Thus, then, inasmuch as the Law is not only a copy of the divine will, but also a mirror of self-knowledge, in which a man may behold and come to know himself, he prays for forgiveness in respect of the many sins of infirmity, - though for the most part unperceived by him, - to which, even the pardoned one succumbs. שׁניאה (in the terminology of the Law, שׁננה, ἀγνόημα) comprehends the whole province of the peccatum involuntarium, both the peccatum ignoranitiae and the peccatum infirmitatis. The question delicta quis intelligit is equivalent to the negative clause: no one can discern his faults, on account of the heart of man being unfathomable and on account of the disguise, oftentimes so plausible, and the subtlety of sin. Hence, as an inference, follows the prayer: pronounce me free also מנּסתּרות, ab occultis (peccatis, which, however, cannot be supplied on grammatical grounds), equivalent to mee`alumiym (Psalm 90:8), i.e., all those sins, which even he, who is most earnestly striving after sanctification, does not discern, although he may desire to know them, by reason of the ever limited nature of his knowledge both of himself and of sin.

(Note: In the Arab proverb, "no sin which is persisted in is small, no sin great for which forgiveness is sought of God," Arab. ṣgı̂rt, directly means a little and Arab. kbı̂rt, a great sin, vid., Allgem. Literar. Zeitschr. 1844, No. 46, p. 363.)

נקּה, δικαιοῦν, is a vox judicialis, to declare innocent, pronounce free from, to let go unpunished. The prayer for justification is followed in Psalm 19:14 by the prayer for sanctification, and indeed for preservation against deliberate sins. From זוּד, זיד, to seethe, boil over, Hiph. to sin wilfully, deliberately, insolently, - opp. of sin arising from infirmity, Exodus 21:14; Deuteronomy 18:22; Deuteronomy 17:12, - is formed זד an insolent sinner, one who does not sin בּשׁננה, but בּזדון (cf. 1 Samuel 17:28, where David's brethren bring this reproach against him), or בּיר רמה, and the neuter collective זדים (cf. סטים, Psalm 101:3; Hosea 5:2) peccata proaeretica or contra conscientiam, which cast one out of the state of grace or favour, Numbers 15:27-31. For if זדים had been intended of arrogant and insolent possessors of power (Ewald), the prayer would have taken some other form than that of "keeping back" (חשׂך as in 1 Samuel 25:39 in the mouth of David). זדים, presumptuous sins, when they are repeated, become dominant sins, which irresistibly enslave the man (משׁל with a non-personal subject, as in Isaiah 3:4, cf. Psalm 103:19); hence the last member of the climax (which advances from the peccatum involuntarium to the proaereticum, and from this to the regnans): let them not have dominion over me (בי with Dech in Baer; generally wrongly marked with Munach).

Then (אז), when Thou bestowest this twofold favour upon me, the favour of pardon and the grace of preservation, shall I be blameless (איתם 1 fut. Kal, instead of אתּם, with י as a characteristic of ē) and absolved (ונקּיתי not Piel, as in Psalm 19:13, but Niph., to be made pure, absolved) from great transgression. פּשׁע

(Note: The Gaja with מפּשׁע is intended in this instance, where מפשׁע רב are to be read in close connection, to secure distinctness of pronunciation for the unaccented ע, as e.g., is also the case in Psalm 78:13, ים בּקע (bāḳa‛jām).)

from פּשׁע (root פש), to spread out, go beyond the bounds, break through, trespass, is a collective name for deliberate and reigning, dominant sin, which breaks through man's relation of favour with God, and consequently casts him out of favour, - in one word, for apostasy. Finally, the psalmist supplicates a gracious acceptance of his prayer, in which both mouth and heart accord, supported by the faithfulness, stable as the rock (צוּרי), and redeeming love (גּואלי redemptor, vindex, root גל, חל, to loose, redeem) of his God. היה לרצון is a standing expression of the sacrificial tra, e.g., Leviticus 1:3. The לפניך, which, according to Exodus 28:38, belongs to לרצון, stands in the second member in accordance with the "parallelism by postponement." Prayer is a sacrifice offered by the inner man. The heart meditates and fashions it; and the mouth presents it, by uttering that which is put into the form of words.
