Genesis 22:4-8

On the third day Abraham raised his eyes and saw the place from a distance.

Then Abraham said to his young men, “Stay here with the donkey, and I and the boy will go over there; and we will worship and return to you.”

And Abraham took the wood for the burnt offering and laid it on his son Isaac, and he took in his hand the fire and the knife. So the two of them walked on together.

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

Abraham said, “God will provide for Himself the lamb for the burnt offering, my son.” So the two of them walked on together.
