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

And Abimelech said to Abraham, What are these seven ewe lambs which you have set by themselves?

And he said, For you shall take these seven ewe lambs from my hand, so that they 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 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, My son, God will provide Himself a lamb for a burnt offering. So they both went together.
