Leviticus 16:27-33

²⁷And the bullock of the sin offering whose blood was carried in to make atonement in the Holy Place, he shall take forth out of the camp, and they shall burn their skins and their flesh and their food with fire.

²⁸And he who burned them must wash his clothes, and bathe his flesh with water, and may then enter into the camp.

²⁹And this shall be to you for an everlasting statute: in the seventh month, on the tenth day of the month, you shall afflict (humble) your souls, and do no work, whether the native-born or the stranger that dwelleth among you.

³⁰For on that day he shall make atonement for you, to cleanse you from all your sins, that you may be cleansed from all your sins before the Lord.

³¹A Sabbath it shall be to you, and you shall humble your souls. It is an everlasting statute.

³²And the priest whom he shall anoint, and who shall offer his oblation, to minister instead of his father, shall make the atonement, and dress himself with the vestments of fine linen, even the consecrated vestments.

³³And he shall make atonement for the Holy of Holies, and for the tabernacle of ordinance and for the altar he shall atone, and for all the people of the congregation shall he atone.
