1 Samuel 24:16-19

16When David finished saying this, Saul asked, “Is that your voice, David my son?” And he wept aloud. 17“You are more righteous than I,” he said. “You have treated me well, but I have treated you badly. 18You have just now told me about the good you did to me; the Lord delivered me into your hands, but you did not kill me. 19When a man finds his enemy, does he let him get away unharmed? May the Lord reward you well for the way you treated me today.
