Genesis 22:10-12

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

11But 1the angel of the Lord called to him from heaven and said, “Abraham, Abraham!” And he said, “Here I am.”

12He said, “Do not stretch out your hand against the lad, and do nothing to him; for now 2I know that you 3fear God, since you have not withheld 4your son, your only son, from Me.”
