The LORD spoke to Moses, after the death of the two sons of Aaron, when they drew near before the LORD and died; and the LORD said to Moses, "Tell Aaron your brother not to come at all times into the holy place within the veil, before the mercy seat which is upon the ark, lest he die; for I will appear in the cloud upon the mercy seat. But thus shall Aaron come into the holy place: with a young bull for a sin offering and a ram for a burnt offering. He shall put on the holy linen coat, and shall have the linen breeches on his body, be girded with the linen girdle, and wear the linen turban; these are the holy garments. He shall bathe his body in water, and then put them on. And he shall take from the congregation of the people of Israel two male goats for a sin offering, and one ram for a burnt offering.
"And Aaron shall offer the bull as a sin offering for himself, and shall make atonement for himself and for his house. Then he shall take the two goats, and set them before the LORD at the door of the tent of meeting; and Aaron shall cast lots upon the two goats, one lot for the LORD and the other lot for Aza'zel. And Aaron shall present the goat on which the lot fell for the LORD, and offer it as a sin offering; but the goat on which the lot fell for Aza'zel shall be presented alive before the LORD to make atonement over it, that it may be sent away into the wilderness to Aza'zel.
"Aaron shall present the bull as a sin offering for himself, and shall make atonement for himself and for his house; he shall kill the bull as a sin offering for himself. And he shall take a censer full of coals of fire from the altar before the LORD, and two handfuls of sweet incense beaten small; and he shall bring it within the veil and put the incense on the fire before the LORD, that the cloud of the incense may cover the mercy seat which is upon the testimony, lest he die; and he shall take some of the blood of the bull, and sprinkle it with his finger on the front of the mercy seat, and before the mercy seat he shall sprinkle the blood with his finger seven times.
"Then he shall kill the goat of the sin offering which is for the people, and bring its blood within the veil, and do with its blood as he did with the blood of the bull, sprinkling it upon the mercy seat and before the mercy seat; 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 abides with them in the midst of their uncleannesses. There shall be no man in the tent of meeting when 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 which is before the LORD and make atonement for it, and shall take some of the blood of the bull and of the blood of the goat, and put it on the horns of the altar round about. And he shall sprinkle some of the blood upon it with his finger seven times, and cleanse it and hallow it from the uncleannesses of the people of Israel."
