Leviticus 23:40-43

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.’”

Deuteronomy 16:13-15

The Festival of Temporary Shelters

16:13 You must celebrate the Festival of Temporary Shelters for seven days, at the time of the grain and grape harvest. 16:14 You are to rejoice in your festival, you, your son, your daughter, your male and female slaves, the Levites, the resident foreigners, the orphans, and the widows who are in your villages. 16:15 You are to celebrate the festival seven days before the Lord your God in the place he chooses, for he will bless you in all your productivity and in whatever you do; so you will indeed rejoice!

Zechariah 14:16-19

14:16 Then all who survive from all the nations that came to attack Jerusalem will go up annually to worship the King, the Lord who rules over all, and to observe the Feast of Tabernacles. 14:17 But if any of the nations anywhere on earth refuse to go up to Jerusalem to worship the King, the Lord who rules over all, they will get no rain. 14:18 If the Egyptians will not do so, they will get no rain – instead there will be the kind of plague which the Lord inflicts on any nations that do not go up to celebrate the Feast of Tabernacles. 14:19 This will be the punishment of Egypt and of all nations that do not go up to celebrate the Feast of Tabernacles.

John 7:2
