Leviticus 23:33

30 Whatever soul it be who does any manner of work in that same day, that soul will I destroy from among his people.

31 You shall do no manner of work: it is a statute forever throughout your generations in all your dwellings.

32 It shall be to you a Sabbath of solemn rest, and you shall afflict your souls: in the ninth day of the month at even, from even to even, shall you keep your Sabbath.

34 Speak to the children of Israel, saying, On the fifteenth day of this seventh month is the feast of tents for seven days to Yahweh.

35 On the first day shall be a holy convocation: you shall do no servile work.

36 Seven days you shall offer an offering made by fire to Yahweh: on the eighth day shall be a holy convocation to you; and you shall offer an offering made by fire to Yahweh: it is a solemn assembly; you shall do no servile work.
