Genesis 22:8-13

8And Abraham said, My son, 1God will provide himself with the sheep for a burnt-offering. And they went both of them together.

9And they came to the place of which 2God 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.

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

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

12And he said, Stretch not out thy hand against the lad, neither do anything to him; for now I know that thou fearest 3God, and hast not withheld thy son, thine only [son], from me.

13And Abraham lifted up his eyes, and looked, and behold, behind was a ram caught in the thicket by its horns; and Abraham went and took the ram, and offered it up for a burnt-offering instead of his son.
