Genesis 22:6-12

6So Abraham took the wood of the burnt offering and laid it on Isaac his son; and he took the fire in his hand, and a knife, and the two of them went together.

7But Isaac spoke to Abraham his father and said, “My father!” And he said, “Here I am, my son.” Then he said, “Look, the fire and the wood, but where is the lamb for a burnt offering?”

8And Abraham said, “My son, God will provide for Himself the lamb for a burnt offering.” So the two of them went together.

9Then 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.

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

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

12And 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.”
