Targum zu Dewarim 32:36

For the Word of the Lord adjudgeth in His mercy the judgement of His people Israel, and for the evil He hath appointed upon His servants there shall be repentance before Him; for He knoweth that in the time when they have sinned the stroke of their enemies will be heavy upon them, and help have passed away from their hands, and the faithful will have failed with their good works and be scattered and forsaken.

For the Lord Himself will adjudge the judgment of the people of the children of Israel, and comfort His righteous servants; for it is manifest before Him that the hand of the righteous will waver, and that they will be forsaken and cast down, with none to help or support them.
