1 Samuel 24:19-21

Revised Standard Version

¹⁹ For if a man finds his enemy, will he let him go away safe? So may the Lord reward you with good for what you have done to me this day. ²⁰ And now, behold, I know that you shall surely be king, and that the kingdom of Israel shall be established in your hand. ²¹ Swear to me therefore by the Lord that you will not cut off my descendants after me, and that you will not destroy my name out of my father’s house.”
