Genesis 22:4-6

New Revised Standard Version, Anglicised 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.
