Genesis 22:10-12 Darby Translation (DARBY)
10 And Abraham stretched out his hand, and took the knife to slaughter his son.
11 And the Angel of Jehovah called to him from the heavens, and said, Abraham, Abraham! And he said, Here am I.
12 And he said, Stretch not out thy hand against the lad, neither do anything to him; for now I know that thou fearest God, and hast not withheld thy son, thine only [son], from me.
