Deuteronomy 33:29

Thine enemies shall be found liars unto thee. — See Psalms 66:3 : “Through the greatness of thy power shall thine enemies submit themselves (i.e., lie) unto thee.” The idea is, that the enemies of the conqueror will hasten to throw themselves at his feet, protesting that they were always his friends. (Compare Shimei’s repentance on the occasion of David’s return to Jerusalem, 2 Samuel 19:18.)
