Leviticus 16:15-17

Darby Translation

¹⁵ And he shall slaughter the goat of the sin-offering, which is for the people, and bring its blood inside the veil, and do with its blood as he did with the blood of the bullock, and sprinkle it upon the mercy-seat, and before the mercy-seat;

¹⁶ and he shall make atonement for the sanctuary, [to cleanse it] from the uncleanness of the children of Israel, and from their transgressions in all their sins; and so shall he do for the tent of meeting which dwelleth among them in the midst of their uncleanness.

¹⁷ And there shall be no man in the tent of meeting when he goeth in to make atonement in the sanctuary until he come out; and he shall make atonement for himself, and for his house, and for the whole congregation of Israel.
