Leviticus 16:29-31

AKJV(i) 29 And this shall be a statute for ever to you: that in the seventh month, on the tenth day of the month, you shall afflict your souls, and do no work at all, whether it be one of your own country, or a stranger that sojournes among you: 30 For on that day shall the priest make an atonement for you, to cleanse you, that you may be clean from all your sins before the LORD. 31 It shall be a sabbath of rest to you, and you shall afflict your souls, by a statute for ever.
