1 Samuel 24:16-19

16So it was, when David had finished speaking these words to Saul, that Saul said, “Is this your voice, my son David?” And Saul lifted up his voice and wept.

17Then he said to David: “You are more righteous than I; for you have rewarded me with good, whereas I have rewarded you with evil.

18And you have shown this day how you have dealt well with me; for when the Lord delivered me into your hand, you did not kill me.

19For if a man finds his enemy, will he let him get away safely? Therefore may the Lord reward you with good for what you have done to me this day.
