Genesis 22:8 KJV

6And Abraham took the wood of the burnt offering, and laid it upon Isaac his son; and he took the fire in his hand, and a knife; and they went both of them together.

7And Isaac spake unto Abraham his father, and said, My father: and he said, Here am I, my son. And he said, Behold the fire and the wood: but where is the lamb for a burnt offering?

8And Abraham said, My son, God will provide himself a lamb for a burnt offering: so they went both of them together.

9And they came to the place which God had told him of; and Abraham built an altar there, and laid the wood in order, and bound Isaac his son, and laid him on the altar upon the wood.

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