Genesis 22:10-12 World English Bible (WEB)
10 Abraham stretched out his hand, and took the knife to kill his son.
11 Yahweh’s angel called to him out of the sky, and said, “Abraham, Abraham!”
He said, “Here I am.”
12 He said, “Don’t lay your hand on the boy or do anything to him. For now I know that you fear God, since you have not withheld your son, your only son, from me.”
