Leviticus 23:33-43 Christian Standard Bible (CSB)
33 The Lord spoke to Moses: 34 “Tell the Israelites: The Festival of Shelters[a] to the Lord begins on the fifteenth day of this seventh month and continues for seven days. 35 There is to be a sacred assembly on the first day; you are not to do any daily work. 36 You are to present a fire offering to the Lord for seven days. On the eighth day you are to hold a sacred assembly and present a fire offering to the Lord. It is a solemn gathering; you are not to do any daily work.
37 “These are the Lord’s appointed times that you are to proclaim as sacred assemblies for presenting fire offerings to the Lord, burnt offerings and grain offerings, sacrifices and drink offerings, each on its designated day. 38 These are in addition to the offerings for the Lord’s Sabbaths, your gifts, all your vow offerings, and all your freewill offerings that you give to the Lord.
39 “You are to celebrate the Lord’s festival on the fifteenth day of the seventh month for seven days after you have gathered the produce of the land. There will be complete rest on the first day and complete rest on the eighth day. 40 On the first day you are to take the product of majestic trees—palm fronds, boughs of leafy trees, and willows of the brook—and rejoice before the Lord your God for seven days. 41 You are to celebrate it as a festival to the Lord seven days each year. This is a permanent statute for you throughout your generations; celebrate it in the seventh month. 42 You are to live in shelters for seven days. All the native-born of Israel must live in shelters, 43 so that your generations may know that I made the Israelites live in shelters when I brought them out of the land of Egypt; I am the Lord your God.”
Deuteronomy 16:13-15 Christian Standard Bible (CSB)
The Festival of Shelters
13 “You are to celebrate the Festival of Shelters for seven days when you have gathered in everything from your threshing floor and winepress. 14 Rejoice during your festival—you, your son and daughter, your male and female slave, as well as the Levite, the resident alien, the fatherless, and the widow within your city gates. 15 You are to hold a seven-day festival for the Lord your God in the place he chooses, because the Lord your God will bless you in all your produce and in all the work of your hands, and you will have abundant joy.
