Genesis 22:4-6

New Revised Standard Version Catholic Edition

⁴ On the third day Abraham looked up and saw the place far away. ⁵ Then Abraham said to his young men, “Stay here with the donkey; the boy and I will go over there; we will worship, and then we will come back to you.” ⁶ Abraham took the wood of the burnt offering and laid it on his son Isaac, and he himself carried the fire and the knife. So the two of them walked on together.
