Genesis 22:5-8

5“Stay here with the donkey,” Abraham told his servants. “The boy and I will go over there to worship, and then we will return to you.”

6Abraham took the wood for the burnt offering and placed it on his son Isaac. He himself carried the fire and the sacrificial knife, and the two of them walked on together.

7Then Isaac said to his father Abraham, “My father!”

“Here I am, my son,” he replied.

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

8Abraham answered, “God Himself will provide the lamb for the burnt offering, my son.” And the two walked on together.
