"Now it came to pass after these things that God tested Abraham, and said to him, "Abraham!" And he said, "Here I am."
"Then He said, "Take now your son, your only son Isaac, whom you love, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I shall tell you."
"So Abraham rose early in the morning and saddled his donkey, and took two of his young men with him, and Isaac his son; and he split the wood for the burnt offering, and arose and went to the place of which God had told him . . .
"Then they came to the place of which God had told him. And Abraham built an altar there and placed the wood in order; and he bound Isaac his son and laid him on the altar, upon the wood. And Abraham stretched out his hand and took the knife to slay his son.
"But the Angel of the Lord called to him from heaven and said, "Abraham, Abraham!" So he said, "Here I am." And He said, 'Do not lay your hand on the lad, 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.'
"Then Abraham lifted his eyes and looked, and there behind him was a ram caught in a thicket by its horns. So Abraham went and took the ram, and offered it up for a burnt offering instead of his son." (Genesis 22:1-3, 9-13, NKJV)
