Leviticus 16:29-31

EJ2000(i) 29 ¶ And you shall hold this as a perpetual statute: In the seventh month, on the tenth day of the month, ye shall afflict your souls and do no work at all, whether it is a natural of your own country or a stranger that sojourns among you; 30 for on that day he shall reconcile you to cleanse you that ye may be clean from all your sins before the LORD. 31 It shall be a sabbath of rest unto you, and ye shall afflict your souls, by a perpetual statute.
