LEVITICUS 16:1-6

¹And the LORD spake unto Moses, after the death of the two sons of Aaron, when they drew near before the LORD, and died;

²and the LORD said unto Moses, Speak unto Aaron thy brother, that he come not at all times into the holy place within the veil, before the mercy-seat which is upon the ark; that he die not: for I will appear in the cloud upon the mercy-seat.

³Herewith shall Aaron come into the holy place: with a young bullock for a sin offering, and a ram for a burnt offering.

⁴He shall put on the holy linen coat, and he shall have the linen breeches upon his flesh, and shall be girded with the linen girdle, and with the linen mitre shall he be attired: they are the holy garments; and he shall bathe his flesh in water, and put them on.

⁵And he shall take of the congregation of the children of Israel two he-goats for a sin offering, and one ram for a burnt offering.

⁶And Aaron shall present the bullock of the sin offering, which is for himself, and make atonement for himself, and for his house.
