Genesis 22:9-12 ▼

9 And they come to the place of which God has spoken to him, and there Abraham builds the altar, and arranges the wood, and binds his son Isaac, and places him on the altar above the wood;

10 and Abraham puts forth his hand, and takes the knife—to slaughter his son.

11 And the Messenger of YHWH calls to him from the heavens and says, “Abraham, Abraham”; and he says, “Here I [am]”;

12 and He says, “Do not put forth your hand to the youth, nor do anything to him, for now I have known that you are fearing God, and have not withheld your son, your only one, from Me.”
