Psalms 3:2 - Coke's Commentary on the Holy Bible

Lord, how are they increased that trouble me!— This psalm answers in every part of it to the inscription. When David was resettled on his throne he penned it, to commemorate both his danger and his deliverance. David begins it with a representation of his danger. Absalom had stolen away the hearts of many of the people. Achitophel aimed at his destruction; and Shimei, with others of his enemies, reproached him, as utterly forsaken of his God; while many of his friends undoubtedly trembled for his safety; and had Achitophel's advice been followed, his ruin, morally speaking, would have been unavoidable. The language in the second verse seems to have been that of his enemies, who imagined that they had him as their prey so secure, that God himself was not able to deliver him. Thus the chief priests, scribes, and elders, insulted his great son, the Messiah, when they had brought him to the cross; bidding defiance to the power of God himself to rescue him out of their hands. See Matthew 27:43 and Chandler.
