Leviticus 23:28-32

King James Version

²⁸ And ye shall do no work in that same day: for it is a day of atonement, to make an atonement for you before the Lord your God.

²⁹ For whatsoever soul it be that shall not be afflicted in that same day, he shall be cut off from among his people.

³⁰ And whatsoever soul it be that doeth any work in that same day, the same soul will I destroy from among his people.

³¹ Ye shall do no manner of work: it shall be a statute for ever throughout your generations in all your dwellings.

³² It shall be unto you a sabbath of rest, and ye shall afflict your souls: in the ninth day of the month at even, from even unto even, shall ye celebrate your sabbath.
