1 Samuel 24:20-22

21st Century King James Version

²⁰ And now, behold, I know well 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 swore unto Saul. And Saul went home, but David and his men got themselves up unto the stronghold.
