Leviticus 23:31

28 And ye shall 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 whatsoever soul it be that shall not be afflicted in that same day; he shall be cut off from his people.

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

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

32 It 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.

33 And Jehovah spake unto Moses, saying,

34 Speak unto the children of Israel, saying, On the fifteenth day of this seventh month is the feast of tabernacles for seven days unto Jehovah.
