Leviticus 23:36

33 Yahweh spoke to Moses, saying,

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.

37 These are the set feasts of Yahweh, which you shall proclaim to be holy convocations, to offer an offering made by fire to Yahweh, a burnt offering, and a meal-offering, a sacrifice, and drink-offerings, each on its own day;

38 besides the Sabbaths of Yahweh, and besides your gifts, and besides all your vows, and besides all your freewill-offerings, which you give to Yahweh.

39 However on the fifteenth day of the seventh month, when you have gathered in the fruits of the land, you shall keep the feast of Yahweh seven days: on the first day shall be a solemn rest, and on the eighth day shall be a solemn rest.
