Genesis 22:7-9 New Life Version (NLV)
7 Then Isaac said to Abraham, “My father!” Abraham answered, “Here I am, my son.” Isaac said, “See, here is the fire and the wood. But where is the lamb for the burnt gift?” 8 Abraham said, “God will have for Himself a lamb ready for the burnt gift, my son.” So the two of them walked on together.
9 Then they came to the place that God told them about. Abraham built the altar there, and set the wood in place. Then he tied rope around his son Isaac, and laid him upon the wood on the altar.
