Leviticus 16:15, 16, 20, 33
Aaron shall then slaughter the goat for the sin offering for the people and bring its blood behind the veil, and with its blood he must do as he did with the bull’s blood: He is to sprinkle it against the mercy seat and in front of it. / So he shall make atonement for the Most Holy Place because of the impurities and rebellious acts of the Israelites in regard to all their sins. He is to do the same for the Tent of Meeting which abides among them, because it is surrounded by their impurities. / When Aaron has finished purifying the Most Holy Place, the Tent of Meeting, and the altar, he is to bring forward the live goat.
