Jeremiah 15:15

Here, as before, we have, I. The prophet's humble address to God, containing a representation both of his integrity and of the hardships he underwent notwithstanding. It is a matter of comfort to us that, whatever ails us, we have a God to go to, before whom we may spread our case and to whose omniscience we may appeal, as the prophet here, "O Lord! thou knowest; thou knowest my sincerity, which men are resolved they will not acknowledge; thou knowest my distress, which men disdain to take notice of." Observe here, 1. What it is that the prophet prays for, Jer 15:15. (1.) That God would consider his case and be mindful of him: "O Lord! remember me; think upon me for good." (2.) That God would communicate strength and comfort to him: "Visit me; not only remember me, but let me know that thou rememberest me, that thou art nigh unto me." (3.) That he would appear for him against those that did him wrong: Revenge me of my persecutors, or rather, Vindicate me from my persecutors; give judgment against them, and let that judgment be executed so far as is necessary for my vindication and to compel them to acknowledge that they have done me wrong. Further than this a good man will not desire that God should avenge him.

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.
