Leviticus 16:27-30

²⁷'And the bullock of the sin-offering, and the goat of the sin-offering, whose blood hath been brought in to make atonement in the sanctuary, doth one bring out unto the outside of the camp, and they have burnt with fire their skins, and their flesh, and their dung;

²⁸and he who is burning them doth wash his garments, and hath bathed his flesh with water, and afterwards he cometh in unto the camp.

²⁹'And it hath been to you for a statute age-during, in the seventh month, in the tenth of the month, ye humble yourselves, and do no work — the native, and the sojourner who is sojourning in your midst;

³⁰for on this day he maketh atonement for you, to cleanse you; from all your sins before Jehovah ye are clean;
