Genesis 22:9-12 ▼

9 Then they came to the place of which God had told him; and Abraham built the altar there and arranged the wood and bound his son Isaac and put him on the altar, on top of the wood.

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

11 But the angel of Yahweh called to him from heaven and said, “Abraham, Abraham!” And he said, “Here I am.”

12 And He said, “Do not stretch out your hand against the boy, and do nothing to him; for now I know that you fear God, since you have not withheld your son, your only one, from Me.”
