John Gill Bible Commentary

Let me not be ashamed, O Lord,.... The same petition as in Psa 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.
