Genesis 21:24 Meaning

22And it came to pass at that time, that Abimelech and Phichol the chief captain of his host spake unto Abraham, saying, God is with thee in all that thou doest:

23Now therefore swear unto me here by God that thou wilt not deal falsely with me, nor with my son, nor with my son's son: but according to the kindness that I have done unto thee, thou shalt do unto me, and to the land wherein thou hast sojourned.

24And Abraham said, I will swear.

25And Abraham reproved Abimelech because of a well of water, which Abimelech's servants had violently taken away.

26And Abimelech said, I wot not who hath done this thing: neither didst thou tell me, neither yet heard I of it, but to day.
