16. Let all those that seek thee be glad and rejoice in thee: and let those that love thy salvation say continually, Jehovah be magnified! 17. But I am poor and needy: Jehovah hath regarded me; thou art my help and my deliverer: O thou my God! make no delay.

16. Let all those that seek thee be glad and rejoice in thee. David here uses another argument -- one which he often adduces elsewhere -- in order to obtain deliverance; not that it is necessary to allege reasons to persuade God, but because it is profitable to confirm our faith by such supports. As, then, it is the will of God that he should be known in his gracious character, not only of one or two, but generality of all men, whenever he vouchsafes deliverance to any of his children, it is a common benefit which all the faithful ought to apply to themselves when they see in the person of one man in what manner God, who is never inconsistent with himself, will act towards all his people. David, therefore, shows that he asks nothing for himself individually but what pertains to the whole Church. He prays that God would gladden the hearts of all the saints, or afford them all common cause of rejoicing: so that, assured of his readiness to help them, they may have recourse to him with greater alacrity. Hence we conclude, that, in the case of every individual, God gives a proof of his goodness towards us. What is added, those that love thy salvation, is also worthy of being observed by us. We may infer from this, that our faith is only proved to be genuine when we neither expect nor desire preservation otherwise than from God alone. Those who devise various ways and means of preservation for themselves in this world, despise and reject the salvation which God has taught us to expect from him alone. What had been said before, those who seek thee, is to the same purpose. If any individual would depend wholly upon God, and desire to be saved by his grace, he must renounce every vain hope, and employ all his thoughts towards the reception of his strength. Here, again, we must observe that two things are contrasted with each other. Formerly David had said that the wicked sought his life; now he ascribes to the faithful quite a contrary feeling, namely, that they seek God. In like manner he had related the reproaches and derision of the ungodly, while they said, Aha, aha! and now he introduces the godly speaking very differently, saying, The Lord be magnified!

17. But I am poor and needy. In this concluding clause he mingles prayer with thanksgiving, although it may be that he records a request which he had made when he was placed in extreme danger. The first clause of the verse might be rendered thus: Although I was miserable and poor, God did think upon me. As according to the extent in which any one is afflicted, so is he despised by the world, we imagine that he is disregarded by God, we must, therefore, steadfastly maintain that our miseries in no respect produce on the part of God a feeling of weariness towards us, so that it should become troublesome to him to aid us. In this way, however, let us rather read the clause: When I was miserable and poor, the Lord looked upon my necessity: So that by this circumstance he enhances the grace of God. If God anticipate us with his goodness, and do not wait till adversity presses upon us, then his favor towards us is not so apparent. This comparison, therefore, illustrates very clearly the glory of God in the deliverance of David, inasmuch as he vouchsafed to stretch forth his hand to a man who was despised and rejected of all men, nay, who was destitute of all help and hope. Now, if it was necessary that David should have been reduced to this extremity, it is no wonder if persons in a more private station are often humbled after this manner, that they may feel and acknowledge in good earnest that they have been delivered out of despair by the hand of God. The simple and natural meaning of the prayer is this, Lord, thou art my help and my deliverer, therefore delay not to come to my aid. As it is a foolish thing to approach God with a doubtful and wavering mind, the Psalmist takes courage, as he was wont to do from his own experience, and persuades himself that the help of God, by which he had been hitherto preserved, would not fail him.
