Leviticus 16:16-18

16And he shall make an atonement for the holy place, because of the uncleanness of the children of Israel, and because of their transgressions in all their sins: and so shall he do for the tabernacle of the congregation, that remaineth among them in the midst of their uncleanness.1 17And there shall be no man in the tabernacle of the congregation when he goeth in to make an atonement in the holy place, until he shall come out, and shall have made an atonement for himself, and for his household, and for all the congregation of Israel. 18And he shall go out to the altar that is before the LORD, and make an atonement for it; and shall take of the blood of the bull, and of the blood of the goat, and put it upon the horns of the altar on all sides.
