Genesis 22:5

3Abraham rose early in the morning, and saddled his donkey; and took two of his young men with him, and Isaac his son. He split the wood for the burnt offering, and rose up, and went to the place of which God had told him.

4On the third day Abraham lifted up his eyes, and saw the place far off.

5Abraham said to his young men, “Stay here with the donkey. The boy and I will go over there. We will worship, and come back to you.”

6Abraham took the wood of the burnt offering and laid it on Isaac his son. He took in his hand the fire and the knife. They both went together.

7Isaac spoke to Abraham his father, and said, “My father?” He said, “Here I am, my son.” He said, “Here is the fire and the wood, but where is the lamb for a burnt offering?”
