Sucot

(14) And you shall rejoice in your feast, you, and your son, and your daughter, and your man-servant, and your maid-servant, and the Levite, and the stranger, and the fatherless, and the widow, that are within your gates. (15) Seven days you shall keep a feast for the LORD your God in the place which the LORD shall choose; because the LORD thy God shall bless you in all your increase, and in all the work of your hands, and you shall be altogether joyful.

Serve Hashem with joy

(42) Você viverá em cabines sete dias; todos os cidadãos em Israel viverão em cabines (43) , para que as futuras gerações possam saber que eu fiz o povo israelita viver em cabines quando os tirei da terra do Egito, eu, o SENHOR, seu Deus.

The Sages taught: All seven days of Sukkot, a person renders his sukka his permanent residence and his house his temporary residence. How so? If he has beautiful vessels, he takes them up to the sukka, which was typically built on the roof. If he has beautiful bedding, he takes it up to the sukka. He eats and drinks and relaxes in the sukka. The Gemara asks: From where are these matters derived? The Gemara explains that it is as the Sages taught: “In sukkot shall you reside” (Leviticus 23:42), and they interpreted: Reside as you dwell in your permanent home. From here they said: All seven days, a person renders his sukka his permanent residence and his house his temporary residence. How so? If he has beautiful vessels, he takes them up to the sukka; if he has beautiful bedding, he takes it up to the sukka; he eats and drinks and relaxes in the sukka and studies Torah in the sukka.

(40) On the first day, you must take for yourself Etrog, Lulav, Hadas & Aravah

There is no person who fulfills her obligation on the first day with a friend's lulav that she borrowed because it's not "to yourselves" (Leviticus 23:40).

(12) The four species are likened to different categories in the Jewish people. The Etrog, which has both taste and smell, is likened to those that study Torah and do mitzvot. The palm branch, which has taste, but no smell, is likened to those who have only Torah study. The myrtle, which has smell but no taste, is likened to those who have only mitzvot. The willow, which has neither taste nor smell, is likened to those who are without Torah study and without mitzvot. [...] And what does God do to them? Does God make them lost [from our nation]? Impossible. Rather, God says "bind them all together and let them atone one for the other." […] Because of this, Moses warns Israel, "And you (plural) shall take for you (plural) on this first day."

(14) Rabbi Mani opened, "'All of my bones shall say, "Lord, who is like you"' (Psalms 35:10). This verse was only stated for the sake of the lulav (the four species). The spine of the palm branch is similar to the spine of man. And the myrtle is similar to the eye. And the willow is similar to the mouth. And the etrog (citron), is similar to the heart. David said, 'In all of the limbs, there are no greater ones than these, as they are compared to the entire body.' This is [what is meant] by 'All of my bones shall say.'"

MISHNA: All seven days of Sukkot, a person renders his sukka his permanent residence and his house his temporary residence. If rain fell, from when is it permitted to vacate the sukka? It is permitted from the point that it is raining so hard that the congealed dish will spoil. The Sages told a parable: To what is this matter comparable? It is comparable to a servant who comes to pour wine for his master, and he pours a jug [kiton] of water in his face to show him that his presence is not desired. So too, in the sukka, rain is an indication that the Holy One, Blessed be He, does not want the person to fulfill the mitzva of sukka.

As it is taught in a baraita that the verse states: “I made the children of Israel to reside in sukkot”; these booths were clouds of glory, this is the statement of Rabbi Eliezer. Rabbi Akiva says: They established for themselves actual sukkot.
