Leviticus 16:4-6

Authorized (King James) 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 a linen girdle, and with the linen mitre shall he be attired: these are holy garments; therefore shall he wash his flesh in water, and so put them on. ⁵ And he shall take of the congregation of the children of Israel two kids of the goats for a sin offering, and one ram for a burnt offering. ⁶ And Aaron shall offer his bullock of the sin offering, which is for himself, and make an atonement for himself, and for his house.
