1 Samuel 24:21

And now, behold, I know that thou shalt surely reign, and the kingdom of Israel shall be established in thy hand.

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.

Swear now therefore to me by Yahweh that you will not cut off my offspring after me, and that you will not destroy my name out of my father’s house.”
