Leviticus 16:24-32

²⁴And he shall bathe his flesh in water in a holy place and put on his other vestments, and come forth, and offer his burnt-offering and the burnt-offering of the people, and make atonement for himself and for the people.

²⁵And the fat of the sin-offering shall he make smoke upon the altar.

²⁶And he that letteth go the goat for Azazel shall wash his clothes, and bathe his flesh in water, and afterward he may come into the camp.

²⁷And the bullock of the sin-offering, and the goat of the sin-offering, whose blood was brought in to make atonement in the holy place, shall be carried forth without the camp; and they shall burn in the fire their skins, and their flesh, and their dung.

²⁸And he that burneth them shall wash his clothes, and bathe his flesh in water, and afterward he may come into the camp.

²⁹And it shall be a statute for ever unto you: in the seventh month, on the tenth day of the month, ye shall afflict your souls, and shall do no manner of work, the home-born, or the stranger that sojourneth among you.

³⁰For on this day shall atonement be made for you, to cleanse you; from all your sins shall ye be clean before the LORD.

³¹It is a sabbath of solemn rest unto you, and ye shall afflict your souls; it is a statute for ever.

³²And the priest, who shall be anointed and who shall be consecrated to be priest in his father's stead, shall make the atonement, and shall put on the linen garments, even the holy garments.
