thou knowest - namely, my case; what wrongs my adversaries have done me (Jer 12:3).
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 (Luk 23:34; Act 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 (Psa 69:7, Psa 69:22-28), which last compare with Jeremiah’s prayer in the beginning of this verse.
