Leviticus

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. ³³And the Lord spake unto Moses, saying, ³⁴Speak unto the children of Israel, saying, On the fifteenth day of this seventh month is the feast of tabernacles for seven days unto the Lord.
