Leviticus 23:27-29

MLV(i) 27 However on the tenth day of this seventh month is the day of atonement. It will be a holy convocation to you* and you* will afflict your* souls and you* will offer an offering made by fire to Jehovah. 28 And you* will 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 whatever soul it is who will not be afflicted in that same day, he will be cut off from his people.
