Verse 17. - Let me not be ashamed, O Lord (see the comment on ver. l). For I have called upon thee. "I have," i.e., "been ever thy true worshipper." Even when I have sinned (ver. 10), my sins have not been "sins of unfaithfulness," but lapses, sins of infirmity, unpremeditated yieldings to temptation. Let the wicked be ashamed. Bring shame, i.e., upon those who are at once my enemies and thine - the wicked and impenitent generally - and, among them on my present adversaries, those who are collected together to carry on war against me. And let them be silent in the grave; or, in Sheol. Let a stop be put to their slanders (ver. 13) and lying speeches (ver. 18); let them he silenced by removal from this world to the land of the departed.

31:9-18 David's troubles made him a man of sorrows. Herein he was a type of Christ, who was acquainted with grief. David acknowledged that his afflictions were merited by his own sins, but Christ suffered for ours. David's friends durst not give him any assistance. Let us not think it strange if thus deserted, but make sure of a Friend in heaven who will not fail. God will be sure to order and dispose all for the best, to all those who commit their spirits also into his hand. The time of life is in God's hands, to lengthen or shorten, make bitter or sweet, according to the counsel of his will. The way of man is not in himself, nor in our friend's hands, nor in our enemies' hands, but in God's. In this faith and confidence he prays that the Lord would save him for his mercies's sake, and not for any merit of his own. He prophesies the silencing of those that reproach and speak evil of the people of God. There is a day coming, when the Lord will execute judgment upon them. In the mean time, we should engage ourselves by well-doing, if possible, to silence the ignorance of foolish men.Let me not be ashamed, O Lord,.... The same petition as in Psalm 31:1;

for I have called upon thee; who is nigh unto all that call upon him in truth, and is rich unto them, and has promised to help and save them; which should he not do, not only he would be made ashamed, but the promise of God would seem to fail: for the psalmist does not plead any duty of his, nor make a merit of his prayers; but has respect to the promise and faithfulness of God;

let the wicked be ashamed; as they will be, sooner or later, of their wickedness, and of their false trust and confidence; of their being incensed against Christ, and their rage against his people, and persecution of them;

and let them be silent in the grave; as all are that are there; and the sense is, let them be brought to the grave, where they will be silent, or cease (f); that is, from their evil words and works, and particularly from troubling the saints, Job 3:17.

(f) "Verbum est" "quod significat cessare ab aliquo opere, vel sermone", Psal. iv. 5. Gejerus.
