1 Samuel 24:19-21

Young's Literal Translation

¹⁹ and that a man doth find his enemy, and hath sent him away in a good manner; and Jehovah doth repay thee good for that which thou didst to me this day.

²⁰ `And, now, lo, I have known that thou dost certainly reign, and the kingdom of Israel hath stood in thy hand;

²¹ and, now, swear to me by Jehovah -- thou dost not cut off my seed after me, nor dost thou destroy my name from the house of my father.'
