Psalms 40:17

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.
