1 Samuel 24:16-19

16And it came to pass, when David had made an end of speaking these words unto Saul, that 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 Yhwh had delivered me into thine hand, thou killedst me not.1 19For if a man find his enemy, will he let him go well away? wherefore Yhwh reward thee good for that thou hast done unto me this day.
