Genesis 21:25-30

25Now Abraham had rebuked Abimelech because of the well of water that Abimelech’s servants had seized.

26So Abimelech said, “I don’t know who did this thing. Nor did you tell me, nor did I hear about it until today.”

27Then Abraham took a flock of sheep and cattle and gave them to Abimelech, and the two of them made a covenant.

28Abraham set seven young ewe-lambs apart from the flock of sheep by themselves.

29Abimelech said to Abraham, “What do these seven ewe-lambs that you’ve set by themselves mean?”

30He said, “You are to accept the seven ewe-lambs from my hand, so that they may be a witness for me that I dug this well.”
