Genesis 22:9-12

Darby Translation

⁹ And they came to the place of which God had told him. And Abraham built the altar there, and piled the wood; and he bound Isaac his son, and laid him on the altar upon the wood.

¹⁰ And Abraham stretched out his hand, and took the knife to slaughter his son.

¹¹ And the Angel of Jehovah called to him from the heavens, and said, Abraham, Abraham! And he said, Here am I.

¹² And he said, Stretch not out thy hand against the lad, neither do anything to him; for now I know that thou fearest God, and hast not withheld thy son, thine only [son], from me.
