Genesis 22:9-11

Living Bible

⁹ When they arrived at the place where God had told Abraham to go, he built an altar and placed the wood in order, ready for the fire, and then tied Isaac and laid him on the altar over the wood. ¹⁰ And Abraham took the knife and lifted it up to plunge it into his son, to slay him.

¹¹ At that moment the Angel of God shouted to him from heaven, “Abraham! Abraham!”

“Yes, Lord!” he answered.
