O LORD, thou knowest: remember me, and visit me, and revenge me of my persecutors; take me not away in thy longsuffering: know that for thy sake I have suffered rebuke.
Thou knowest - namely, my case: what wrongs my adversaries have done me (Jeremiah 12:3).
Revenge me - (note, Jeremiah 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 unholy. Contrast the prayer of the dying Saviour, and of His first martyr, Stephen (Luke 23:34, "Father, forgive them, for they know not what they do;" Acts 7:60, "Lord, lay not this sin to their charge"). At the same time, denunciations of the ungodly occur in the Gospel too: and love to enemies, on the other hand, is also taught in the law. So perfectly do both Testaments mutually harmonize.
Take me not away in thy long-suffering - by thy long-suffering toward 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 (Psalms 69:7; Psalms 69:22-28), which last ("Pour out thine indignation upon them," etc.) compare with Jeremiah's prayer in the beginning of this verse.
