Leviticus 16:30

The bull for the sin offering, and the goat for the sin offering, whose blood was brought in to make atonement in the Holy Place, shall be carried outside the camp; and they shall burn their skins, their flesh, and their dung with fire.

He who burns them shall wash his clothes, and bathe his flesh in water, and afterward he shall come into the camp.

“It shall be a statute to you forever: in the seventh month, on the tenth day of the month, you shall afflict your souls, and shall do no kind of work, whether native-born or a stranger who lives as a foreigner among you;

It is a Sabbath of solemn rest to you, and you shall afflict your souls. It is a statute forever.

The priest, who is anointed and who is consecrated to be priest in his father’s place, shall make the atonement, and shall put on the linen garments, even the holy garments.

Then he shall make atonement for the Holy Sanctuary; and he shall make atonement for the Tent of Meeting and for the altar; and he shall make atonement for the priests and for all the people of the assembly.
