Genesis 21:22-24

22Now it came about at that time that 1Abimelech and Phicol, the commander of his army, spoke to Abraham, saying, “2God is with you in all that you do;

23so now, 3swear to me here by God that you will not deal falsely with me or with my offspring or with my descendants, but according to the kindness that I have shown to you, you shall show to me and to the land in which you have resided.”

24Abraham said, “I swear it.”
