Eruvin 29

ERUVIN 26-29 has been sponsored by Rabbi and Mrs. Eli Turkel of Ra'anana, Israel


(a) What is a dish of beet-roots good for, and how well should they be cooked?

(b) What did Rava mean when he said that he was like Ben Azai in the markets of Teverya?

(c) What did Rava answer when he was asked what quantity of apples was required for an Eruv?
(Note: the Sugya is speaking about wild apples - Hagahos Oshri Si'man 1. See also Tosfos 27b end of DH 'Aval').

(a) What does the Beraisa mean when it writes: 'Kol ha'Ochlin Mitztarfin Lifsol es ha'Gevi'ah'?

(b) Why is the fact that the Beraisa says 'Kol ha'Ochlin' (which seems to include apples) not a Kashya on Rava - who says that apples cannot be used for an Eruv)?

(c) The Beraisa continues 'u've'Mazon Sh'tei Se'udos le'Eruv, u'che'Beitzah Letamei Tum'as Ochlin'.
How does that disprove Rava?

(d) So what *is* the quantity of apples required for an Eruv?

(a) The Beraisa gives the Shiur of various foods: an eighth of a Lug of spices, a Lug of vegetables, ten nuts and five peaches, two pomegranates and one Esrog.
Which two areas of Halachah does this concern?

(b) The Gemara assumes that the Shiur of apples should be equivalent to that of Afarsekin.
Why, in fact, are they not?

(c) The Mishnah in Pe'ah lists the minimum quantities of a. grain, and b. liquids of Ma'aser Oni that one is obligated to give to a poor man: a. half a Kav of wheat, a Kav of barley, one a half Kabin of spelt, a Kav of dried figs, or a Manah (weight) of pressed ones; b. a Lug of wine and a quarter of a Lug of oil.
Which two commodities are not eligible to be used for an Eruv?

(d) Seeing as Rav's statement 've'Chen le'Eruv' applies equally, in most cases, to the Beraisa (quoted in a.) as it does to this Mishnah, why was Rav Yosef so upset with Rav Menasheh bar Seguvli for actually quoting it on the Beraisa?

(a) What did Rabah tell Rav Yosef, when he contended that, when two foods combine for an Eruv, each must consist of at least enough for one meal?

(b) How do we reconcile Rav, who requires half a Lug of wine for an Eruv, with the Beraisa, which gives the Shiur as enough to soak one's bread in?

(c) The Shiur for vinegar that is needed for an Eruv is enough for dipping in vegetables for two meals.
What are the two interpretations of 'vegetables for two meals'?

(a) How do we reconcile Rebbi Shimon ben Elazar in one Beraisa, who includes onions among the commodities that are eligible to be used for an Eruv, and the same Tana, in another Beraisa, quoting Rebbi Meir, who disqualifies them?

(b) Under which two conditions are onion-leaves not dangerous?

(c) What happened to Rebbi Chanina, when he ate half an onion with half its poison?

Answers to questions



(a) Rebbi Zeira quotes Shmuel, who says that beer is eligible to use for an Eruv, and three Lugin of it invalidate a Mikvah?
What is the Chidush of the latter statement? Why might we have thought that beer would *not* invalidate a Mikvah?

(b) How does 'Trein Revai Shikra' in our Sugya mean two Lugin, and why did Rav Acha Brei de'Rav Yosef think that two Lugin of beer are required for an Eruv?

(c) On what grounds does the Gemara reject that contention?

(a) 'Achal Gerogeros ve'Shilam Temarim, Tavo Alav Berachah'.
How does Rav Yosef explain this Beraisa, and what is his reason for this?

(b) How does he prove from there that the quantity of dates required for an Eruv is one Kav (twenty-four egg-volumes)?

(c) How does Abaye refute Rav Yosef's proof?

(d) What is the Shiur Eruv of Shesisa (a dish including honey made from flour which in turn, was made from kernels roasted in the oven and dried)?

(a) Abaye's nurse was a particularly knowledgeable woman.
How, according to her, would the above-mentioned parched ears of corn make a person healthier and give him a better disposition?

(b) Against which type of disorder did she teach Abaye to eat the meat of the right thigh of a ram roasted in either cow's dung or coals from chips of a willow-tree?

(c) What did she recommend that one drink afterwards?

(a) What is the difference between something that is eaten as a condiment and something that is eaten independently (with regard to using it for the two meals of an Eruv)?

(b) In the same regard, what is the difference - according to Rabah, between raw meat and roasted meat?

(c) What does Rav Yosef hold?

(a) Rav Yosef proves his point from the Persians, who used to eat pieces of roasted meat independently.
What is Abaye's objection to this?

(b) The minimum Shiur of a rich man's clothes is three by three Tefachim; of a poor man's clothes, three finger-breadths by three finger-breadths. A rich man's clothes only receive Tum'as Medras (see Tosfos DH 'Bigdei) if they are at least three Tefachim by three Tefachim.
What is the Shiur for Tum'as Medras of a poor man's clothes, and how does Abaye prove his point from here?

(c) How does the Gemara refute the attempted answer that we go Lechumra in both cases?

(d) Do we have an answer to Abaye's Kashya (which really leaves Rav Yosef unanswered)?
