Leviticus 23:27-44

23:27 “The tenth day of this seventh month is the Day of Atonement. It is to be a holy assembly for you, and you must humble yourselves and present a gift to the Lord. 23:28 You must not do any work on this particular day, because it is a day of atonement to make atonement for yourselves before the Lord your God. 23:29 Indeed, any person who does not behave with humility on this particular day will be cut off from his people. 23:30 As for any person who does any work on this particular day, I will exterminate that person from the midst of his people! 23:31 You must not do any work. This is a perpetual statute throughout your generations in all the places where you live. 23:32 It is a Sabbath of complete rest for you, and you must humble yourselves on the ninth day of the month in the evening, from evening until evening you must observe your Sabbath.”

The Festival of Booths

23:33 The Lord spoke to Moses: 23:34 “Tell the Israelites, ‘On the fifteenth day of this seventh month is the Festival of Temporary Shelters for seven days to the Lord. 23:35 On the first day is a holy assembly; you must do no regular work. 23:36 For 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.

23:37 “‘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, 23:38 besides the Sabbaths of the Lord and all your gifts, votive offerings, and freewill offerings which you must give to the Lord.

23:39 “‘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. 23:40 On the first day you must take for yourselves branches from majestic trees – palm branches, branches of leafy trees, and willows of the brook – and you must rejoice before the Lord your God for seven days. 23:41 You must celebrate it as a pilgrim festival to the Lord for seven days in the year. This is a perpetual statute throughout your generations; you must celebrate it in the seventh month. 23:42 You must live in temporary shelters for seven days; every native citizen in Israel must live in temporary shelters, 23:43 so that your future generations may know that I made the Israelites live in temporary shelters when I brought them out from the land of Egypt. I am the Lord your God.’”

23:44 So Moses spoke to the Israelites about the appointed times of the Lord.
