This is the Feast of Yahuah established by God as an annual and last holiday of the year.
It lasts from the 15th go to the 22nd day of the seventh month Tishri of the Creator’s calendar.
“33And יהוה spoke to Mosheh, saying,
34Speak to the children of Yisra’ĕl, saying, ‘On the fifteenth day of this seventh new moon is the Festival of Sukkot for seven days to יהוה.
35‘On the first day is a set-apart gathering, you do no servile work.
36‘For seven days you bring an offering made by fire to יהוה. On the eighth day there shall be a set-apart gathering for you, and you shall bring an offering made by fire to יהוה. It is a closing festival, you do no servile work.
37‘These are the appointed times of יהוה which you proclaim as set-apart gatherings, to bring an offering made by fire to יהוה, an ascending offering and a grain offering, a slaughtering and drink offerings, as commanded for every day –
38besides the Sabbaths of יהוה, and besides your gifts, and besides all your vows, and besides all your voluntary offerings which you give to יהוה.
39‘On the fifteenth day of the seventh new moon, when you gather in the fruit of the land, celebrate the festival of יהוה for seven days. On the first day is a rest, and on the eighth day a rest.
40‘And you shall take for yourselves on the first day the fruit of good trees, branches of palm trees, twigs of leafy trees, and willows of the stream, and shall rejoice before יהוה your Elohim for seven days.
41‘And you shall celebrate it as a festival to יהוה for seven days in the year – a law forever in your generations. Celebrate it in the seventh new moon.
42‘Dwell in booths for seven days; all who are native born in Yisra’ĕl dwell in booths,
43so that your generations know that I made the children of Yisra’ĕl dwell in booths when I brought them out of the land of Mitsrayim. I am יהוה your Elohim.’ ”
44Thus did Mosheh speak of the appointed times of יהוה to the children of Yisra’ĕl.”
“12“And you shall remember that you were a slave in Mitsrayim, and you shall guard and do these laws.
13Perform the Festival of Sukkot for seven days after the ingathering from your threshing-floor and from your winepress,
14and you shall rejoice in your festival, you and your son and your daughter, and your male servant and your female servant, and the Lĕwite, and the stranger and the fatherless and the widow who are within your gates.
15“For seven days you shall celebrate to יהוה your Elohim in the place which יהוה chooses, because יהוה your Elohim does bless you in all your increase and in all the work of your hands, and you shall be only rejoicing!
16Three times a year all your males appear before יהוה your Elohim in the place which He chooses: at the Festival of Matzot, and at the Festival of Shaḇu’ot, and at the Festival of Sukkot. And none should appear before יהוה empty-handed,
17but each one with the gift of his hand, according to the blessing of יהוה your Elohim which He has given you.”
“10And Mosheh commanded them, saying, “At the end of seven years, at the appointed time, the year of release, at the Festival of Sukkot,
11when all Yisra’ĕl comes to appear before יהוה your Elohim in the place which He chooses, read this Torah before all Yisra’ĕl in their hearing.
12“Assemble the people, the men and the women and the little ones, and your sojourner who is within your gates, so that they hear, and so that they learn to fear יהוה your Elohim and guard to do all the Words of this Torah.
13“And their children, who have not known it, should hear and learn to fear יהוה your Elohim as long as you live in the land you are passing over the Yardĕn to possess.”
“12Then Shelomoh offered ascending offerings to יהוה on the slaughter-place of יהוה which he had built before the porch,
13even as the duty of every day required, offering according to the command of Mosheh, for the sabbaths, and for the new moons, and for the appointed times three times a year: the Festival of Matzot, and the Festival of Shaḇu’ot, and the Festival of Sukkot.”
2 Chronicles 8:12-13
“1Now when the seventh new moon came, and the children of Yisra’ĕl were in the cities, the people gathered as one man to Yerushalayim.
2And Yĕshua son of Yotsaḏaq and his brothers the priests, and Zerubbaḇel son of She’alti’ĕl and his brothers, arose and built the slaughter-place of the Elohim of Yisra’ĕl, to offer ascending offerings on it, as it is written in the Torah of Mosheh, the man of Elohim.
3So they set the slaughter-place on its stands, being afraid of the peoples of the lands. And they offered ascending offerings on it to יהוה, both the morning and evening ascending offerings.
4And they performed the Festival of Sukkot, as it is written, and the daily ascending offerings by number, according to the right-ruling for each day,
5and afterward the continual ascending offering, and those for new moons and for all the appointed times of יהוה that were set-apart, also for everyone who volunteered a voluntary offering to יהוה.”
“18And if the clan of Mitsrayim does not come up and enter in, then there is no rain. On them is the plague with which יהוה plagues the nations who do not come up to celebrate the Festival of Sukkot.
19This is the punishment of Mitsrayim and the punishment of all the nations that do not come up to celebrate the Festival of Sukkot.
20In that day “SET-APART TO יהוה” shall be engraved on the bells of the horses. And the pots in the House of יהוה shall be like the bowls before the slaughter-place.
21And every pot in Yerushalayim and Yehuḏah shall be set-apart to יהוה of hosts. And all those who slaughter shall come and take them and cook in them. And there shall no longer be a merchant in the House of יהוה of hosts, in that day.”
