Sukkoth is also known as the Feast of the Ingathering, the Festival of Booths, the Feast
of Tabernacles and other variations. It is a seven day festival which is commanded in
Scripture by Yahweh, with a closing festival on the eighth day.

Wayyiqra (Leviticus) 23:33-44

Lev. 23:33 And Yahweh spoke to Moshe, saying,
Lev. 23:34 "Speak to the children of Yisra'el, saying, 'On the fifteenth day of this seventh month is the Festival of Booths for seven days to Yahweh.
Lev. 23:35 'On the first day is a set-apart gathering, you do no servile work.
Lev. 23:36 'For seven days you bring an offering made by fire to Yahweh. On the eighth day there shall be a set-apart gathering for you, and you shall bring an offering made by fire to Yahweh. It is a closing festival, you do no servile work.
Lev. 23:37 'These are the appointed times of Yahweh which you proclaim as set-apart gatherings, to bring an offering made by fire to Yahweh, a burnt offering and a grain offering, a slaughtering and drink offerings, as commanded for every day -
Lev. 23:38 besides the Sabbaths of Yahweh, and besides your gifts, and besides all your vows, and besides all your voluntary offerings which you give to Yahweh.
Lev. 23:39 'On the fifteenth day of the seventh month, when you gather in the fruit of the land, observe the festival of Yahweh for seven days. On the first day is a rest, and on the eighth day a rest.
Lev. 23:40 '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 Yahweh your Elohim for seven days.
Lev. 23:41 'And you shall observe it as a festival to Yahweh for seven days in the year - a law forever in your generations. Observe it in the seventh month.
Lev. 23:42 'Dwell in booths for seven days; all who are native Yisra'elites dwell in booths,
Lev. 23:43 so that your generations know that I made the children of Yisra'el dwell in booths when I brought them out of the land of Mitsrayim. I am Yahweh your Elohim.' "
Lev. 23:44 Thus did Mosheh speak of the appointed times of Yahweh to the children of Yisra'el.

Sukkoth is one of the pilgrimage festivals which Yahweh commanded B’nai Yisrael (children of Israel) to perform. This festival commemorates Yisrael’s (Israel’s) wandering in the wilderness. It takes its name from the fact that the Yisraelites lived in tents (sukkah) during this time. The festival begins on the 15th day of the seventh month and lasts for seven days.

The feast is a time of gladness and thankfulness to Yahweh for Yahweh’s provision at the end of the agricultural season (Wayyiqra [Lev.] 23:39-41). It is also a reminder (Debarim [Deut.] 16:13), to the people, of Yahweh’s care for his own, whom he had rescued from Mitsrayim (Egypt) during those long years in the wilderness (Wayyiqra 23:42-43). It is the time of our rejoicing (z’man simchatenu)!

The feast is closed by a day of rest, with a set-apart gathering, marking not only the climax of a religious year, but symbolizing the rest of the believer in his Creator (Wayyiqra 23:39). Prophetically, the feast finds final fulfillment in that grand day when Yahweh will raise up the fallen booth of Dawid (Amos 9:11) and give shelter to his repentant, redeemed, and regathered people (Yeshayah [Isaiah] 4:6).
