Leviticus 23:32

29 For any person, whoever he may be, who takes his pleasure on that day will be cut off from his people.

30 And if any person, whoever he may be, on that day does any sort of work, I will send destruction on him from among his people.

31 You may not do any sort of work: this is an order for ever through all your generations wherever you may be living.

32 Let this be a Sabbath of special rest to you, and keep yourselves from all pleasure; on the ninth day of the month at nightfall from evening to evening, let this Sabbath be kept.

33 And the Lord said to Moses,

34 Say to the children of Israel, On the fifteenth day of this seventh month let the feast of tents be kept to the Lord for seven days.

35 On the first day there will be a holy meeting: do no field-work.
