Genesis 22:6-8

New Revised Standard Version Catholic Edition

⁶ Abraham took the wood of the burnt offering and laid it on his son Isaac, and he himself carried the fire and the knife. So the two of them walked on together. ⁷ Isaac said to his father Abraham, “Father!” And he said, “Here I am, my son.” He said, “The fire and the wood are here, but where is the lamb for a burnt offering?” ⁸ Abraham said, “God himself will provide the lamb for a burnt offering, my son.” So the two of them walked on together.
