Leviticus 23:27-29

American Standard Version

²⁷ Howbeit on the tenth day of this seventh month is the day of atonement: it shall be a holy convocation unto you, and ye shall afflict your souls; and ye shall offer an offering made by fire unto Jehovah. ²⁸ And ye shall do no manner of work in that same day; for it is a day of atonement, to make atonement for you before Jehovah your God. ²⁹ For whatsoever soul it be that shall not be afflicted in that same day; he shall be cut off from his people.
