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

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

And he said, These seven ewe lambs shalt thou take of my hand, that it may be a witness unto me, that I have digged this well.

And Isaac spake unto Abraham his father, and said, My father. And he said, Here am I, my son. And he said, Behold, the fire and the wood. But where is the lamb for a burnt-offering?

And Abraham said, God will provide himself the lamb for a burnt-offering, my son. So they went both of them together.
