revenge me—(See on Jer 11:20). The prophet in this had regard to, not his own personal feelings of revenge, but the cause of God; he speaks by inspiration God's will against the ungodly. Contrast in this the law with the gospel (Lu 23:34; Ac 7:60).
take me not away in thy long-suffering—By Thy long-suffering towards them, suffer them not meanwhile to take away my life.
for thy sake I have suffered rebuke—the very words of the antitype, Jesus Christ (Ps 69:7, 22-28), which last compare with Jeremiah's prayer in the beginning of this verse.
