Genesis 21:27

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.”

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

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

29Abimelech said to Abraham, “What do these seven ewe lambs, which you have set by themselves, mean?”
