Genesis 22:8

And 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.

And 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?

And 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.

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