It is a scripture honoring thing.
Leviticus 23:33
Then the Lord spoke to Moses, saying, 34 “Speak to the children of Israel, saying: ‘The fifteenth day of this seventh month shall be the Feast of Tabernacles for seven days to the Lord. 35 On the first day there shall be a holy convocation. You shall do no customary work on it. 36 For seven days you shall offer an offering made by fire to the Lord. On the eighth day you shall have a holy convocation, and you shall offer an offering made by fire to the Lord. It is a sacred assembly, and you shall do no customary work on it.

39 ‘Also on the fifteenth day of the seventh month, when you have gathered in the fruit of the land, you shall keep the feast of the Lord for seven days; on the first day there shall be a sabbath-rest, and on the eighth day a sabbath-rest. 40 And you shall take for yourselves on the first day the fruit of beautiful trees, branches of palm trees, the boughs of leafy trees, and willows of the brook; and you shall rejoice before the Lord your God for seven days. 41 You shall keep it as a feast to the Lord for seven days in the year. It shall be a statute forever in your generations. You shall celebrate it in the seventh month. 42 You shall dwell in booths for seven days. All who are native Israelites shall dwell in booths, 43 that your generations may know that I made the children of Israel dwell in booths when I brought them out of the land of Egypt: I am the Lord your God.’ ”
I neglected to add in that I (for the past 25 years) have bought a Lulav-etrog set as part of the Sukkot celebration:

"The fruit of beautiful trees" = etrog. It is a type of citron.
"The branches of palm trees" = lulav.
"Tabernacle" = "booth" = sukkah (sukkot is the plural)
The Talmuds say a lot of things. Some is good, some is ok, some is bad. They had hundreds if not thousands of contributors. We do not consider it scripture or binding, but historical; and parts of it can be useful. The rest we ignore.
Stick to scripture when discussing and doing the things of the Lord.
It's not good to leave out verses when quoting the scriptures.
These are the feasts of the LORD which you shall proclaim to be holy convocations,
to offer an offering made by fire to the LORD, a burnt offering and a grain offering, a sacrifice and drink offerings, everything on its day— Leviticus 33:37
On the fifteenth day of the seventh month you shall have a holy convocation. You shall do no customary work, and you shall keep a feast to the LORD seven days. You shall present a burnt offering, an offering made by fire as a sweet aroma to the LORD: thirteen young bulls, two rams, and fourteen lambs in their first year. They shall be without blemish. Their grain offering shall be of fine flour mixed with oil: three-tenths of an ephah for each of the thirteen bulls, two-tenths for each of the two rams, and one-tenth for each of the fourteen lambs; also one kid of the goats as a sin offering, besides the regular burnt offering, its grain offering, and its drink offering. ‘On the second day present twelve young bulls, two rams, fourteen lambs in their first year without blemish, also one kid of the goats as a sin offering, besides the regular burnt offering, its grain offering, and its drink offering. ‘On the second day present twelve young bulls, two rams, fourteen lambs in their first year without blemish, and their grain offering and their drink offerings for the bulls, for the rams, and for the lambs, by their number, according to the ordinance; also one kid of the goats as a sin offering, besides the regular burnt offering with its grain offering, and their drink offerings. ‘On the third day present eleven bulls, two rams, fourteen lambs in their first year without blemish, and their grain offering and their drink offerings for the bulls, for the rams, and for the lambs, by their number, according to the ordinance; also one goat as a sin offering, besides the regular burnt offering, its grain offering, and its drink offering.
Numbers 29:12-22
Literally a different animal sacrifice for 7 days.
