7th month /15th Day - 4th from Sabbath (wednesday) : Sukkot

Jubilees 16:21

And he (Abraham) built booths for himself and for his servants on this festival, and he was the first to celebrate the feast of tabernacles on the earth.

Leviticus 23h

33 The Lord said to Moses,

34 “Say to the Israelites: ‘On the fifteenth day of the seventh month the Lord’s Festival of Tabernacles begins, and it lasts for seven days.

35 The first day is a sacred assembly; do no regular work.

36 For seven days present food offerings to the Lord, and on the eighth day hold a sacred assembly and present a food offering to the Lord. It is the closing special assembly; do no regular work.

37 These are the Lord’s appointed festivals, which you are to proclaim as sacred assemblies for bringing food offerings to the Lord—the burnt offerings and grain offerings, sacrifices and drink offerings required for each day.

38 These offerings are in addition to those for the Lord’s Sabbaths and in addition to your gifts and whatever you have vowed and all the freewill offerings you give to the Lord.

39 So beginning with the fifteenth day of the seventh month, after you have gathered the crops of the land, celebrate the festival to the Lord for seven days; the first day is a day of sabbath rest, and the eighth day also is a day of sabbath rest.

40 On the first day you are to take branches from luxuriant trees—from palms, willows and other leafy trees—and rejoice before the Lord your God for seven days.

41 Celebrate this as a festival to the Lord for seven days each year. This is to be a lasting ordinance for the generations to come; celebrate it in the seventh month.

42 Live in temporary shelters for seven days: All native-born Israelites are to live in such shelters

43 so your descendants will know that I had the Israelites live in temporary shelters when I brought them out of Egypt. I am the Lord your God.’”

44 So Moses announced to the Israelites the appointed festivals of the Lord.

Deuteronomy 16

13 Celebrate the Festival of Tabernacles for seven days after you have gathered the produce of your threshing floor and your winepress.

14 Be joyful at your festival—you, your sons and daughters, your male and female servants, and the Levites, the foreigners, the fatherless and the widows who live in your towns.

15 For seven days celebrate the festival to the Lord your God at the place the Lord will choose. For the Lord your God will bless you in all your harvest and in all the work of your hands, and your joy will be complete.

16 Three times a year all your men must appear before the Lord your God at the place he will choose: at the Festival of Unleavened Bread, the Festival of Weeks and the Festival of Tabernacles. No one should appear before YHWH empty-handed:

17 Each of you must bring a gift in proportion to the way the Lord your God has blessed you.

Nehemiah 8

13 On the second day of the month, the heads of all the families, along with the priests and the Levites, gathered around Ezra the teacher to give attention to the words of the Law.

14 They found written in the Law, which the LORD had commanded through Moses, that the Israelites were to live in temporary shelters during the festival of the seventh month

15 and that they should proclaim this word and spread it throughout their towns and in Jerusalem: “Go out into the hill country and bring back branches from olive and wild olive trees, and from myrtles, palms and shade trees, to make temporary shelters”–as it is written.

16 So the people went out and brought back branches and built themselves temporary shelters on their own roofs, in their courtyards, in the courts of the house of God and in the square by the Water Gate and the one by the Gate of Ephraim.

17 The whole company that had returned from exile built temporary shelters and lived in them. From the days of Joshua son of Nun until that day, the Israelites had not celebrated it like this. And their joy was very great.

18 Day after day, from the first day to the last, Ezra read from the Book of the Law of God. They celebrated the festival for seven days, and on the eighth day, in accordance with the regulation, there was an assembly.

35 “‘On the eighth day hold a closing special assembly and do no regular work. 36 Present as an aroma pleasing to the Lord a food offering consisting of a burnt offering of one bull, one ram and seven male lambs a year old, all without defect. 37 With the bull, the ram and the lambs, offer their grain offerings and drink offerings according to the number specified. 38 Include one male goat as a sin offering, in addition to the regular burnt offering with its grain offering and drink offering.

39 “‘In addition to what you vow and your freewill offerings, offer these to the Lord at your appointed festivals: your burnt offerings, grain offerings, drink offerings and fellowship offerings.’”

40 Moses told the Israelites all that the Lord commanded him.

Zechariah 14

8And on that day living water will flow out from Jerusalem, half of it toward the Eastern Seab and the other half toward the Western Sea,c in summer and winter alike. 9On that day YHWH will become King over all the earth—YHWH alone, and His name alone. (...)

16Then all the survivors from the nations that came against Jerusalem will go up year after year to worship the King, YHWH of Hosts, and to celebrate the Feast of Tabernacles.d 17And should any of the families of the earth not go up to Jerusalem to worship the King, YHWH of Hosts, then the rain will not fall on them. 18And if the people of Egypt will not go up and enter in, then the rain will not fall on them; this will be the plague with which YHWH strikes the nations who do not go up to celebrate the Feast of Tabernacles. 19This will be the punishment of Egypt and of all the nations that do not go up to celebrate the Feast of Tabernacles.

20On that day, HOLY TO YHWHe will be inscribed on the bells of the horses, and the cooking pots in the house of YHWH will be like the sprinkling bowls before the altar. 21Indeed, every pot in Jerusalem and Judah will be holy to YHWH of Hosts, and all who sacrifice will come and take some pots and cook in them. And on that day there will no longer be a Canaanitef in the house of YHWH of Hosts.
