Leviticus 23:24-32

²⁴Speak unto the children of Israel, saying: In the seventh month, in the first day of the month, shall be a solemn rest unto you, a memorial proclaimed with the blast of horns, a holy convocation.

²⁵Ye shall do no manner of servile work; and ye shall bring an offering made by fire unto the LORD.

²⁶And the LORD spoke unto Moses, saying:

²⁷Howbeit on the tenth day of this seventh month is the day of atonement; there shall be a holy convocation unto you, and ye shall afflict your souls; and ye shall bring an offering made by fire unto the LORD.

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

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

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

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

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