This has been called one of the penitential psalms. It may be called so without any severe strain of language; and yet its penitential tone is very far removed from that of either the thirty-second or the fifty-first psalm. There is little doubt that there is a sincere acknowledgment of the sin; but here the main stress of the grief seems to be attributable rather to the suffering consequent upon the sin, than to the guilt of the sin itself. And we cannot resist the conviction that an undue reticence (which, alas! often results in an infrequent and inadequate warning against sins of the flesh) has somewhat warped and fettered the remarks of many expositors. For the physical suffering which is here detailed with distressing precision, points to sin as the cause thereof - to that sin which is one of the seriously poisoning influences in our social fabric, and against which no pleadings can be too tender, and no warnings can be too loud. Let us first study the case, and then utilize it.

I. THE CASE STATED. Even before entering into detail, it is obvious that the case is one of intense suffering. The details, however, will show us but too clearly what the suffering was, and how it was accounted for.

1. There had been the commission of sin. Vers. 3-5 give us three terms - "sin," "foolishness," "iniquity. The sin was one which brought about a great deal of:

2. Bodily disorder. Note the following expressions:

(1) My flesh" (ver. 3).

(2) "My bones" (ver. 3).

(3) "My loins" (ver. 7).

(4) "No soundness" (ver. 3).

(5) "No health" (ver. 3).

(6) "Wounds" (ver. 5).

(7) "Ulcers" (ver. 5, Hebrew).

(8) "Offensive" (ver. 5).

(9) "Burning" (ver. 7).

(10) This alternating with deathly coldness (ver. 8).

(11) "Palpitation" (ver. 10).

(12) The frame bent and bowed with the suffering (ver. 6).

(13) "Failing strength" (ver. 10).

(14) "Dimness of sight" (ver. 10).

Surely this puts before us, in no obscure fashion, the terrible physical woe which the writer was enduring.

3. (treat mental anguish.

(1) God's arrows struck very deeply into his soul (ver. 2).

(2) God's hand pressed heavily upon him (ver. 2).

(3) He went abroad as a mourner ver. 6).

(4) He roared - groaned aloud - all the day long.

It may not be always possible to affirm that such and such suffering is the effect of this or that specific sin. But sometimes we can. And it is no wonder if sins of the flesh bring fleshly suffering. It is an ordained law of God that it should be so. Hence the sufferings are rightly regarded as "the arrows of God."

4. In his trouble, lovers and friends stand aloof from him. Even neighbours and kinsmen drew themselves afar off (ver. 11). Earthly friends are like swallows, who come near in fine weather, and fly away ere the weather turns foul.

5. He was laden with reproach, and even beset with snares. (Ver. 12.)

6. He did not and could not reply. To the charges laid at his door he had no justifications to offer, and therefore said nothing (cf. ver. 14, Hebrew). This was so far wise.

7. Though silent to man, he pours out his heart to God. He calls God his God; even though guilt lies heavily on the soul.

(1) He declares the whole case before the mercy-seat (ver. 9).

(2) He confesses the sin (ver. 18).

(3) He deprecates the Divine displeasure (ver. 1).

(4) He appeals for help (ver. 22).

Note: There is a great difference between men who "are overtaken in a fault," and those whose life is one perpetual sin of alienation from God. David lived in an age when lustfulness was scarcely recognized as wrong at all, save where the holy Law of God had gleamed on it with the searching light of Heaven. If David fell into this sin, it was because he was injured by the low conventional standard of his day. If he regarded it as sin, and mourned over it, it was because he was under the educating influence of that Word which was as "a lamp to his feet, and a light unto his path."

8. While David moans his sin as threatening him with destruction and ruin, he looks for salvation in God and God alone. (Ver. 22.) "O Lord my Salvation."

II. THE CASE UTILIZED. Here is evidently a psalm which is one of a number that contain a rehearsal of the writer's private experience. They profess to be that, and therefore, unless some good reason to the contrary is shown, we rightly assume that they are that. The expositor who desires to deal faithfully with all the psalms, and with the whole of each psalm, will often find himself between two opposite schools. On one side, there are those who would enclose every psalm within the limits of a naturalistic psychology; while there are others who seem to regard every psalm as referring directly or indirectly to Christ. But while the second and forty-fifth psalm. can by no means be accounted for by a rationalistic psychology, so this thirty-eighth psalm can by no means be applied to the Messiah directly or indirectly. Let us not select facts to fit a theory; but study all the facts, and frame the theory accordingly. In this personal moan and groan we have:

1. Suffering following on sin. Of what kind the sin was there can be little question. And if we wonder that David could fall into such sin, we may well ask - What can be expected of a man who had six wives (2 Samuel 3:2-5)? The Law of God might, indeed, be the rule of his life, but he was injured and corrupted by falling into the conventionalisms of his day; and hence in his private life he came far short of his own professed ideal. Is not the like incongruity between the ideal and the actual often seen even now?

2. If it was owing to "conformity to the world that David thus sinned, it was because he had before him God's revelation of the evil of sin that he was so bowed down under a sense of the guilt thereof. The revealed Law of God stood high above the level to which he had attained; hence a shame and self-loathing on account of sin, which would nowhere else have been known.

3. Smarting under the sense of guilt, David yet tells God all. He knew God to be one pardoning iniquity, transgression, and sin;" and hence the burdens of sin and guilt, as well as of care, were laid before the mercy-seat (Psalm 32:5).

4. At times, however, words fail; then the desire and the groaning are perfectly understood. (Ver. 9.) Who does not understand something of this that knows anything of the "energies of prayer"? There are "groanings which cannot be uttered." As there are "songs without words," so are there "prayers without words." For the grief consequent upon sin may be, and often is, aggravated by the desertion of those friends who will smile on us when we are prosperous, and will turn their backs on us when adversity comes. But, even so, it is an infinite mercy to be shut up to God, and to let the heart lie "naked and opened" before One who will never misunderstand, and who will never forsake us.

5. For our God is "Jehovah our Salvation. That is his revealed name, and to it he will ever be true. See how gloriously the sure mercies of David" are set forth in Psalm 89:26-33. God is "a just God, and a Saviour" (Isaiah 45:21). Hence we should never let our consciousness of guilt drive us from him; rather should it always make us "flee unto" him "to hide us."

6. Hence only those who have the light of God's revelation can possibly have any gospel for men smarting under the guilt of sin. We do not know any one passage in Scripture in which the combination is more remarkable of a man whose sin has brought deepest shame and agony upon him, and who yet is laying hold of God under that beautiful, that matchless name, "my Salvation" (ver. 22). Very often, indeed, the word "salvation" in the Old Testament means mainly, if not exclusively, temporal deliverance. Here, at any rate, it cannot be so limited; for the salvation required to meet the case of woe thus laid before God must be one which includes cancelling guilt, purifying from corruption, and healing disease. And that revelation of God as our Salvation which was made in germ to the Hebrews, is disclosed more fully to us under Christ. He is "made wisdom from God unto us, even righteousness, sanctification, and redemption; that (according as it is written) he that glorieth, let him glory in the Lord" (1 Corinthians 1:30, 31). In the very volume where sin is dealt with most seriously, it is also treated most hopefully; and the very revelation which cries with trumpet-power, "All have sinned," also cries, "Look unto me, and be ye saved." - C.

Our friends should blush, that the wicked are more instant against us, than they are to maintain us. But it is no wonder, since by nature men are more bent and prone to evil than to do good things. By constraint they do good, but willingly they commit evil.

1. Their profit and pastime was to undo me. The order is here inverted; for meditating properly precedeth speaking, and speaking doing; but in the words of the text it is otherways; their malice extendeth to the highest degree, they will not be contented to banish him, prison him, and revile him, nothing can satisfy their thirst but his blood. This is the envy of the serpent against the seed of the woman. The devil is a murderer, and so are his children.

2. The means which they used against him: their purposes, their words, and their actions. They meditated, they consulted; for wrongs done rashly are less dangerous, and more excusable, out of a spleen and choler; but advised evils are more fearful, and more hardly to be eschewed, laying the grounds and pillars of their proceedings upon some sure hold. But we have one advantage, that God is present in all their counsels, and cannot only reveal them, but also disappoint them.

3. Finally, those their meditations and communications, which proceeded from cruel hearts, burst forth in actions which were mixed with craft, and so much the more perilous, for they are said to lay snares for him: taking the metaphor from hunters, fowlers or fishers, whose trade is only to catch birds, beasts and fishes by their engines and policy, seeing hardly they can be taken otherways.
