Leviticus 23:33-39

33The Lord spoke to Moses:

34“Tell the Israelites, ‘On the fifteenth day of this seventh month is the Festival of Temporary Shelters for seven days to the Lord.

35On the first day is a holy assembly; you must do no regular work.

36For seven days you must present a gift to the Lord. On the eighth day there is to be a holy assembly for you, and you must present a gift to the Lord. It is a solemn assembly day; you must not do any regular work.

37“‘These are the appointed times of the Lord that you must proclaim as holy assemblies to present a gift to the Lord – burnt offering, grain offering, sacrifice, and drink offerings, each day according to its regulation,

38besides the Sabbaths of the Lord and all your gifts, votive offerings, and freewill offerings which you must give to the Lord.

39“‘On the fifteenth day of the seventh month, when you gather in the produce of the land, you must celebrate a pilgrim festival of the Lord for seven days. On the first day is a complete rest and on the eighth day is complete rest.
