Genesis 21:23

20 And God was with the boy, and he became tall and strong, and he became a bowman, living in the waste land.

21 And while he was in the waste land of Paran, his mother got him a wife from the land of Egypt.

22 Now at that time, Abimelech and Phicol, the captain of his army, said to Abraham, I see that God is with you in all you do.

23 Now, then, give me your oath, in the name of God, that you will not be false to me or to my sons after me, but that as I have been good to you, so you will be to me and to this land where you have been living.

24 And Abraham said, I will give you my oath.

25 But Abraham made a protest to Abimelech because of a water-hole which Abimelech's servants had taken by force.

26 But Abimelech said, I have no idea who has done this thing; you never gave me word of it, and I had no knowledge of it till this day.
