Abraham separated seven ewe lambs from the flock.

And Abimelech said to Abraham, “Why have you separated these seven ewe lambs?”

He replied, “You are to accept the seven ewe lambs from my hand so that this act will serve as my witness that I dug this well.”

Then Isaac spoke to his father Abraham and said, “My father.”

And he replied, “Here I am, my son.”

Isaac said, “The fire and the wood are here, but where is the lamb for the burnt offering?”

Abraham answered, “God Himself will provide the lamb for the burnt offering, my son.” Then the two of them walked on together.
