Leviticus 16:29-31

CAB(i) 29 And this shall be a perpetual statute for you; in the seventh month, on the tenth day of the month, you shall humble your souls, and shall do no work, the native and the stranger who abides among you. 30 For in this day he shall make an atonement for you, to cleanse you from all your sins before the Lord, and you shall be purged. 31 This shall be to you a most holy Sabbath, a rest, and you shall humble your souls; it is a perpetual ordinance.
