Genesis 21:25

22 It happened at that time, that Abimelech and Phicol the captain of his host spoke to Abraham, saying, "God is with you in all that you do.

23 Now 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 sojourned."

24 Abraham said, "I will swear."

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

26 Abimelech said, I don`t know who has done this thing. Neither did you tell me, neither did I hear of it, until today."

27 Abraham took sheep and oxen, and gave them to Abimelech. Those two made a covenant.

28 Abraham set seven ewe lambs of the flock by themselves.
