Genesis 21:27

Abraham said, “I will swear.”

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

Abimelech said, “I don’t know who has done this thing. You didn’t tell me, and I didn’t hear of it until today.”

Abraham set seven ewe lambs of the flock by themselves.

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

He said, “You shall take these seven ewe lambs from my hand, that it may be a witness to me, that I have dug this well.”
