Genesis 22:10-12

10And Abraham reached out with his hand and took the knife to 1slaughter his son.

11But 2the angel of the Lord called to him from heaven and said, “Abraham, Abraham!” And he said, “Here I am.”

12He said, “Do not reach out your hand against the boy, and do not do anything to him; for now 3I know that you 4fear God, since you have not withheld 5your son, your only son, from Me.”
