Leviticus 16:4-6

American Standard Version

⁴ He 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 ^[a]mitre shall he be attired: they are the holy garments; and he shall bathe his flesh in water, and put them on. ⁵ And 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.

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