1 Samuel 24:19-21

American Standard Version

¹⁹ For if a man find his enemy, will he let him go well away? wherefore Jehovah reward thee good for that which 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 thy hand. ²¹ Swear now therefore unto me by Jehovah, that thou wilt not cut off my seed after me, and that thou wilt not destroy my name out of my father’s house.
