Genesis 22:5-8

5Then Abraham said to his servants, “You stay here with the donkey while the boy and I go over there. We’ll worship. After that we’ll come back to you.”

6Then Abraham took the wood for the burnt offering and gave it to his son Isaac. Abraham carried the burning coals and the knife. The two of them went on together.

7Isaac spoke up and said, “Father?” “Yes, Son?” Abraham answered. Isaac asked, “We have the burning coals and the wood, but where is the lamb for the burnt offering?”

8Abraham answered, “God will provide a lamb for the burnt offering, Son.” The two of them went on together.
