Leviticus 16:29–34

²⁹And this shall be an everlasting statute unto you. In the seventh month, on the tenth of the month, ye shall afflict your souls, and do no work at all, the home-born, and the stranger that sojourneth among you; ³⁰for on that day shall atonement be made for you, to cleanse you: from all your sins shall ye be clean before Jehovah. ³¹A sabbath of rest shall it be unto you, and ye shall afflict your souls: it is an everlasting statute. ³²And the priest who hath been anointed, and who hath been consecrated, to exercise the priesthood in his father’s stead, shall make atonement; and he shall put on the linen garments, the holy garments. ³³And he shall make atonement for the holy sanctuary; and for the tent of meeting, and for the altar shall he make atonement; and for the priests, and for the whole people of the congregation shall he make atonement. ³⁴And this shall be an everlasting statute unto you, to make atonement for the children of Israel to cleanse them from all their sins once a year. And he did as Jehovah had commanded Moses.
