Genesis 22
2 Ref 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.
3 Ref 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.
