2 Samuel 19:22

And David, rejecting the proposal as once before, 2 Samuel 16:10, said, What have I to do with you, ye sons of Zeruiah, that ye should this day be adversaries unto me? The measure suggested by them was altogether out of harmony with his own inclination on this happy occasion. Shall there any man be put to death this day in Israel? For do not I know that I am this day king over Israel? He felt that his restoration to the kingdom really was a proof of his being accepted into the divine favor once more, and he wanted to show his appreciation by being merciful.
