Shiur summary (draft from the recording)
Sukkos of Yotzrim; Sukkas Ganbach and Rakbash
סוכת גנב״ך
Sukkah 8b · Tuesday, July 14, 2026
The sugya
The shiur began with Rabbi Levi's din of two sukkos of yotzrim, one inside the other: the inner one is not a sukkah and needs a mezuzah, and the outer one is a sukkah and is patur from mezuzah. The Gemara asks why the outer one is not treated as a beis shaar, and answers that the setup is not kavua. The main part of the shiur was the two braisos of Ganbach and Rakbash. Each says 'sukkah mikol makom kesheirah' if it is made for shade, and each includes the other group. The Gemara explains that each Tanna saw his own group as the stronger case, and the shiur ended with a review reading for punctuation.
Step by step (shakla v’tarya)
- Plan for the day: first the two sukkos of yotzrim, then the two groups of sukkos called Ganbach and Rakbash, which are packaged very neatly.
- GemaraLine two: craftsmen (yotzrim) set up two sukkos, one deeper than the other. The inner one is not a sukkah and is chayav in mezuzah. The outer one is a sukkah.
- The RebbiThe Rebbi explained that even if an existing living space can serve as a sukkah, the living has to be different. A craftsman who carries on in his inner quarters exactly as every other day has not done anything, so that does not work. Flipping it, so he lives in the outside part where he normally does not live, works.
- KashaWhy is the outer one patur from mezuzah? Let it be like the beis shaar of the inner one, and every such setup obligates the outer one in mezuzah.
- TeirutzThe whole setup is not kavua. It is transportable: you are here, then there. So this beis shaar does not need a mezuzah.
- The Rebbi said he does not think it is a problem for a sukkah to have a mezuzah, for example a sukkah made inside the kitchen. The talmidim discussed a pergola and a backyard fence with a door that served as the sukkah wall all year. The conclusion was that such a mezuzah is needed anyway and has nothing to do with the sukkah.
- GemaraLine seven, Tanu Rabbanan: Ganbach (gimmel, nun, beis, chaf). Sukkas goyim is a regular shaded place where goyim live in the summer. Sukkas nashim is used by women for their things. Sukkas beheimah is an animal shelter or barn. Sukkas Kusim is put in the 'goyim bucket'. All are protected, shaded areas not made for a sukkah.
- GemaraSukkah mikol makom kesheirah, provided that it is mesuchechess k'hilchasa.
- KashaThe Gemara asks: what does k'hilchasa mean?
- TeirutzRav Chisda answers: provided he made it for shade (l'tzel).
- RashiRashi: it has to be shaded well. The Rebbi noted that this sounds like more than a backyard sukkah, where 51% is enough.
- The RebbiIf the covering is skimpy, the structure is for privacy, not shade. Here it has to be clearly for shade.
- KashaAfter four specific cases, what does the extra 'sukkah mikol makom' come to include?
- TeirutzIt includes sukkas Rakbash.
- The Rebbi framed it this way: Ganbach and Rakbash are subsets. Each group has something going for it that the other does not. None of the eight is a traditional backyard sukkah; they are existing structures you find and turn into your sukkah.
- GemaraBraisa of Rakbash. Ro'im: shepherds. Kaytzim: people watching fruit set out to dry ('fruit jerky'). Burganin: explained as a hunter's hut or guard's hut. Shomrei peiros: orchard watchers.
- RashiRashi: Burganin are the watchers of the city. The Rebbi assumed this is the same as a guard's hut.
- GemaraHere too: sukkah mikol makom kesheirah, provided it is shaded like a proper sukkah.
- The RebbiFrom Rashi it seems an obvious purpose of shade is needed. When you build a sukkah in your backyard, the shade does not have to scream at me, since you built it as a sukkah. When you pick out an existing structure, it has to be very clearly intended for shade.
- GemaraIn the Rakbash braisa, 'sukkah mikol makom' comes to include Ganbach. So each set includes the other.
- KashaThe criterion is the same in both: any hut is fine as long as it screams shade. So why are there two braisos, each headed by a different group?
- TeirutzThe Tanna of Ganbach saw Ganbach as stronger (alima lei) because they are kavua, more permanent. Through 'mikol makom' he included Rakbash, which are not kavua: shepherds, fruit dryers and guards move from field to field. The Rebbi put it as Ganbach being the host who invited Rakbash.
- TeirutzThe Tanna of Rakbash saw Rakbash as stronger because the people using them are bnei chiyuva, obligated Jews. Through 'mikol makom' he included Ganbach, who are not bnei chiyuva: goyim, beheimos, nashim, Kusim.
- ChazarahThe whole sugya was reread with punctuation: the Ganbach braisa, Rav Chisda's l'tzel sukkah, the inclusion of Rakbash, the mirror-image Rakbash braisa, and each Tanna's reasoning.
- Side discussion on Kusim: they converted, and it is not known whether it was a good conversion (gerei arayos was mentioned). Whenever Kusim come up, they are their own category.
- RashiOn alima: Rashi says it 'screamed more kashrus', meaning it appeared more kosher. Ganbach is set in place and does not move; it is established, like a sukkah that stays there for seven days.
Kashas
- Why is the outer sukkah of the yotzrim patur from mezuzah? Let it be like a beis shaar of the inner one.
- What does k'hilchasa mean?
- In the Ganbach braisa, what does 'sukkah mikol makom' include?
- In the Rakbash braisa, what does 'sukkah mikol makom' include?
- If the criterion is the same, why are there two braisos, each headed by a different group?
Teirutzim
- The setup of the yotzrim is not kavua; it is transportable.
- Rav Chisda: it must have been made for shade.
- The Ganbach braisa's 'mikol makom' includes Rakbash.
- The Rakbash braisa's 'mikol makom' includes Ganbach.
- To the Tanna of Ganbach, Ganbach is stronger because it is kavua; he adds Rakbash even though it is not kavua.
- To the Tanna of Rakbash, Rakbash is stronger because its users are bnei chiyuva; he adds Ganbach even though its users are not.
Rashi & Tosafos
- Rashi: K'hilchasa / l'tzel: the sukkah has to be shaded well.
- Rashi: Burganin are the watchers of the city.
- Rashi: Alima lei: it appeared more kosher to him ('screamed more kashrus').
The Rebbi’s chiddushim
- Using an existing living space as a sukkah requires changing how you live there. Staying in your usual inner quarters does nothing; moving into the outer part you normally do not live in works.
- Having a mezuzah is not a problem for a sukkah. Where a doorway already needs a mezuzah, that has nothing to do with the sukkah.
- Skimpy covering means the structure is for privacy; here it must clearly be for shade.
- Ganbach and Rakbash are mirror-image subsets, each with its own advantage. All eight are found structures, not built sukkos.
- A sukkah built as a sukkah does not need its shade to be obvious. A found structure must clearly scream shade.
- Ganbach as the host who invited Rakbash, and the reverse in the other braisa.
Unclear in recording
- Part of the discussion about a sukkah in the kitchen and things being temporary was not clear.
- The Rebbi said Burganin appeared earlier ('Where did we have a Burganin?'); the reference was not clear.
- A remark about not getting 'mixed up in sukkah ...' was not clear.
- The end of the shiur, during the reading of the Rakbash Tanna's reasoning, was not clear.
Drafted from the recording of the shiur, for chazarah. Torah terms follow the Rebbi’s own words; anything that could not be made out is marked “unclear in recording”. Tap a time to hear that point. Corrections welcome.
