Leviticus 23:20-29

²⁰And the priest shall wave them with the bread of the first fruits for a wave offering before the Lord, with the two lambs: they shall be holy to the Lord for the priest.

²¹And ye shall proclaim on the selfsame day, that it may be a holy convocation unto you: ye shall do no servile work therein: it shall be a statute for ever in all your dwellings throughout your generations.

²²And when ye reap the harvest of your land, thou shalt not make clean riddance of the corners of thy field when thou reapest, neither shalt thou gather any gleaning of thy harvest: thou shalt leave them unto the poor, and to the stranger: I am the Lord your God.

²³And the Lord spake unto Moses, saying,

²⁴Speak unto the children of Israel, saying, In the seventh month, in the first day of the month, shall ye have a sabbath, a memorial of blowing of trumpets, a holy convocation.

²⁵Ye shall do no servile work therein: but ye shall offer an offering made by fire unto the Lord.

²⁶And the Lord spake unto Moses, saying,

²⁷Also on the tenth day of this seventh month there shall be a day of atonement: it shall be a holy convocation unto you; and ye shall afflict your souls, and offer an offering made by fire unto the Lord.

²⁸And 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.

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