Genesis 22:8-13

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

9When they came to the place that God had told him about, Abraham built the altar and arranged the wood on it. Then he tied up his son Isaac and laid him on top of the wood on the altar.

10Next, Abraham picked up the knife and took it in his hand to sacrifice his son.

11But the Messenger of the Lord called to him from heaven and said, “Abraham! Abraham!” “Yes?” he answered.

12“Do not lay a hand on the boy,” he said. “Do not do anything to him. Now I know that you fear God, because you did not refuse to give me your son, your only son.”

13When Abraham looked around, he saw a ram behind him caught by its horns in a bush. So Abraham took the ram and sacrificed it as a burnt offering in place of his son.
