Leviticus 16:8-10: "8and Aaron shall cast lots upon the two goats, one lot for the Lord and the other lot for Azazel. 9And Aaron shall present the goat on which the lot fell for the Lord, and offer it as a sin offering; 10but the goat on which the lot fell for Azazel shall be presented alive before the Lord to make atonement over it, that it may be sent away into the wilderness to Azazel."
