1 Samuel 24:16-19

16And as soon as David had ended speaking these words to Saul, Saul said, Is this thy voice, my son David? And Saul lifted up his voice and wept.

17And he said to David, Thou art more righteous than I; for thou hast rewarded me good, whereas I have rewarded thee evil.

18And thou hast shewed this day how that thou hast dealt well with me, forasmuch as when Jehovah had delivered me up into thy hand, thou didst not kill me.

19For if a man find his enemy, will he let him go well away? wherefore Jehovah reward thee good for that thou hast done to me this day.
