1 Samuel 24:20-22

New International Reader's Version

²⁰ I know for sure that you will be king. I know that the kingdom of Israel will be made secure under your control. ²¹ Now make a promise in the name of the Lord. Promise me that you won’t kill the children of my family. Also promise me that you won’t wipe out my name from my family line.”

²² So David made that promise to Saul. Then Saul returned home. But David and his men went up to his usual place of safety.
