Leviticus 23:33

31 "You shall do no work at all. It is to be a perpetual statute throughout your generations in all your dwelling places.

32 "It is to be a sabbath of complete rest to you, and you shall humble your souls; on the ninth of the month at evening, from evening until evening you shall keep your sabbath."

33 Again the LORD spoke to Moses, saying,

34 "Speak to the sons of Israel, saying, 'On the fifteenth of this seventh month is the Feast of Booths for seven days to the LORD .

35 'On the first day is a holy convocation; you shall do no laborious work of any kind.
