Genesis 21:24

22At that time, Abimelech and Phicol the captain of his army spoke to Abraham, saying, “God is with you in all that you do.

23Now, therefore, swear to me here by God that you will not deal falsely with me, nor with my son, nor with my son’s son. But according to the kindness that I have done to you, you shall do to me, and to the land in which you have lived as a foreigner.”

24Abraham said, “I will swear.”

25Abraham complained to Abimelech because of a water well, which Abimelech’s servants had violently taken away.

26Abimelech said, “I don’t know who has done this thing. You didn’t tell me, and I didn’t hear of it until today.”
