Genesis 22:10-12 ESV
Then Abraham reached out his hand and took the knife to slaughter his son. But the angel of the LORD called to him from heaven and said, “Abraham, Abraham!” And he said, “Here I am.” He said, “Do not lay your hand on the boy or do anything to him, for now I know that you fear God, seeing you have not withheld your son, your only son, from me.”
