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

And Abimelech said to Abraham, What do these seven ewe lambs mean which thou have set by themselves?

And he said, These seven ewe lambs thou shall take from my hand, that it may be a witness to me, that I have dug this well.

And Isaac spoke to Abraham his father, and said, My father. And he said, Here I am, 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.
