21:27And Abraham took sheep and oxen, and gave them unto Abimelech; and both of them made a covenant.

21:28And Abraham set seven ewe lambs of the flock by themselves.

21:29And Abimelech said unto Abraham, What mean these seven ewe lambs which thou hast set by themselves?

21:30And he said, For these seven ewe lambs shalt thou take of my hand, that they may be a witness unto me, that I have digged this well.
