Genesis 22:1-5

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.
