17 He said to David, “You are more righteous than I; for you have done good to me, whereas I have done evil to you.
18 You have declared today how you have dealt well with me, because when the Lord had delivered me up into your hand, you didn’t kill me.
19 For if a man finds his enemy, will he let him go away unharmed? Therefore may the Lord reward you good for that which you have done to me today.
20 Now, behold, I know that you will surely be king, and that the kingdom of Israel will be established in your hand.
21 Swear now therefore to me by the Lord, that you will not cut off my offspring after me, and that you will not destroy my name out of my father’s house.”
22 David swore to Saul. Saul went home, but David and his men went up to the stronghold.
