Leviticus 16:15-17

Then shall he kill the goat of the sin offering, that {is} for the people, and bring his blood within the vail, and do with that blood as he did with the blood of the bullock, and sprinkle it upon the mercy seat, and before the mercy seat: And 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. {remaineth: Heb. dwelleth} And 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 come out, and have made an atonement for himself, and for his household, and for all the congregation of Israel.
