Leviticus 16:16–18

Thus he shall make atonement for the Holy Place, because of the uncleannesses of the people of Israel and because of their transgressions, all their sins. And so he shall do for the tent of meeting, which dwells with them in the midst of their uncleannesses. No one may be in the tent of meeting from the time he enters to make atonement in the Holy Place until he comes out and has made atonement for himself and for his house and for all the assembly of Israel. Then he shall go out to the altar that is before the Lord and make atonement for it, and shall take some of the blood of the bull and some of the blood of the goat, and put it on the horns of the altar all around.

He will make atonement for the most holy place in this way for all their sins because of the Israelites’ impurities and rebellious acts. He will do the same for the tent of meeting that remains among them, because it is surrounded by their impurities. No one may be in the tent of meeting from the time he enters to make atonement in the most holy place until he leaves after he has made atonement for himself, his household, and the whole assembly of Israel. Then he will go out to the altar that is before the Lord and make atonement for it. He is to take some of the bull’s blood and some of the goat’s blood and put it on the horns on all sides of the altar.

Through this process, he will purify the Most Holy Place, and he will do the same for the entire Tabernacle, because of the defiling sin and rebellion of the Israelites. No one else is allowed inside the Tabernacle when Aaron enters it for the purification ceremony in the Most Holy Place. No one may enter until he comes out again after purifying himself, his family, and all the congregation of Israel, making them right with the Lord.

“Then Aaron will come out to purify the altar that stands before the Lord. He will do this by taking some of the blood from the bull and the goat and putting it on each of the horns of the altar.

Thus he shall make atonement for the sanctuary from the Israelites’ impurities and from their transgressions for all their sins; and so he must do for the tent of assembly, which dwells with them in the midst of their impurities. And no person shall be in the tent of assembly when he enters to make atonement in the sanctuary until he comes out, and so he shall make atonement for himself and for his family and for all of Israel’s assembly.

“Then he shall go out to the altar that is before Yahweh, and he shall make atonement for it; and he shall take some of the bull’s blood and some of the goat’s blood, and he shall put it all around on the altar’s horns.

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. 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. And he shall go out unto the altar that is before the Lord, and make an atonement for it; and shall take of the blood of the bullock, and of the blood of the goat, and put it upon the horns of the altar round about.
