Leviticus 16:4-6

Darby Translation

⁴ A holy linen vest shall he put on, and linen trousers shall be upon his flesh, and he shall be girded with a linen girdle, and with the linen mitre shall he be attired: these are holy garments; and he shall bathe his flesh in water, and put them on.

⁵ And of the assembly of the children of Israel shall he take two bucks of the 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.
