Leviticus 16:29-31

Revised Standard Version Catholic Edition

²⁹ “And it shall be a statute to you for ever that in the seventh month, on the tenth day of the month, you shall afflict yourselves, and shall do no work, either the native or the stranger who sojourns among you; ³⁰ for on this day shall atonement be made for you, to cleanse you; from all your sins you shall be clean before the Lord. ³¹ It is a sabbath of solemn rest to you, and you shall afflict yourselves; it is a statute for ever.
