Genesis 22:8

Abraham 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.”

Abraham 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.

Isaac 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?”

They came to the place which God had told him of. Abraham built the altar there, and laid the wood in order, bound Isaac his son, and laid him on the altar, on the wood.

Abraham stretched out his hand, and took the knife to kill his son.

The LORD’s angel called to him out of the sky, and said, “Abraham, Abraham!”

He said, “Here I am.”
