Genesis 21:24-28

Abraham said, “I swear it.”

But Abraham complained to Abimelech because of the well of water which the servants of Abimelech had seized.

And Abimelech said, “I do not know who has done this thing; you did not tell me, nor did I hear of it until today.”

So Abraham took sheep and oxen and gave them to Abimelech, and the two of them made a covenant.

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