Genesis 21:24

21:23 Now therefore, swear to me by God that you will not deal falsely with me, with my offspring, or with my posterity; but that according to the kindness that I have done to you, you will do to me and to the land in which you have dwelt."

21:24 And Abraham said, "I will swear."

21:25 Then Abraham rebuked Abimelech because of a well of water which Abimelech's servants had seized.
