Genesis 22:1-8

And it came to pass after these things, that God did prove Abraham, and said unto him, Abraham; and he said, Here am I. And he said, Take now thy son, thine only son, whom thou lovest, even Isaac, and get thee into the land of Moriah; and offer him there for a burnt-offering upon one of the mountains which I will tell thee of. And Abraham rose early in the morning, and saddled his ass, and took two of his young men with him, and Isaac his son; and he clave the wood for the burnt-offering, and rose up, and went unto the place of which God had told him. On the third day Abraham lifted up his eyes, and saw the place afar off. And Abraham said unto his young men, Abide ye here with the ass, and I and the lad will go yonder; and we will worship, and come again to you. And Abraham took the wood of the burnt-offering, and laid it upon Isaac his son; and he took in his hand the fire and the 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 Abraham said, God will provide himself the lamb for a burnt-offering, my son: so they went both of them together.
