17 And he said to David, Thou art more righteous than I: for thou hast rendered unto me good, whereas I have rendered unto thee evil.
18 And thou hast declared this day how that thou hast dealt well with me: forasmuch as when the Lord had delivered me up into thine hand, thou killedst me not.
19 For if a man find his enemy, will he let him go well away? wherefore the Lord reward thee good for that thou hast done unto me this day.
20 And now, behold, I know that thou shalt surely be king, and that the kingdom of Israel shall be established in thine hand.
21 Swear now therefore unto me by the Lord, that thou wilt not cut off my seed after me, and that thou wilt not destroy my name out of my father's house.
22 And David sware unto Saul. And Saul went home; but David and his men gat them up unto the hold.
