(a) If a convert who was sharing a series of rooms in a barn in a
courtyard with a Jew, dies, as long as nobody else takes possession of his
section, it is obvious that the Jew is permitted to carry in the
courtyard. What does the Beraisa mean when it says 'Mes Ger Mi'b'od Yom,
Af Al Gav she'Hichzik Yisrael Acher bi'Nechasav, Oser'?
How does Rav
Nachman interpret 'Oser'?
(b) Rebbi Yochanan establishes the author of the two previous Beraisos
(from which we asked on Rav Nachman) to be Beis Shamai.
What do Beis
(a) What is difficult with the statement in the Beraisa (with regard to a
Yisrael and a convert who shared a barn in a courtyard, and the convert
died) 'mi'b'Od Yom, Af Al Pi she'Hichzik Yisrael Acher bi'Nechasav, Oser'?
(b) How does Rav Papa amend the Beraisa and explain it? Why will we not
apply the principle 'Kol she'Mutar le'Miktzas Shabbos' ... ?
(c) According to Beis Hillel, Bitul Reshus helps even on Shabbos. Ula
tries to compare this to the case of 'K'lach Eitzel Yafos'. What is the
case of 'K'lach Eitzel Yafos', and what is the attempted comparison to
(d) The Gemara however, rejects this comparison outright.
What then, is
the basis of the Machlokes between Beis Hillel and Beis Shamai (regarding
whether Bitul Reshus helps on Shabbos or not)?
(a) If Reuven is a partner in both of his neighbors - Shimon and Levi's
wine businesses, the three neighbors do not require an Eruv. This is not
the case if one of his neighbors owns a wine business, and the other, an
oil business. According to Rav, the difference lies in how many vessels
are being used.
What does this mean?
(b) What proof does Rava bring for this?
(c) On what grounds does Abaye reject Rava's proof?
(a) 'Rebbi Shimon Omer, Echad Zeh ve'Echad Zeh, Einan Tzerichin Eruv'.
This appears to be highly illogical, since the two commodities are not fit
Answers to questions
How does Rabah explain Rebbi Shimon? What is his source?
(b) Are Shimon and Levi (the two outer neighbors) permitted to carry from
one to the other?
(c) What do the Rabbanan now hold, and what is their reasoning?
(d) How do we explain Rebbi Shimon's words 'Ein Tzerichin le'Arev'? To
whom does this pertain?
(a) Rav Yosef interprets our Mishnah by one Mavoy (like we did
originally). According to him, Rebbi Shimon follows the opinion of Rebbi
Yochanan ben Nuri, and the Rabbanan that of the Rabbanan, in their
Machlokes regarding oil floating on wine.
What is the Machlokes there?
(b) How will we now explain Rebbi Shimon's opinion?
(a) Rebbi Elazar ben Tadai holds that even if Shimon and Levi are both
wine-merchants, they require an Eruv.
If, as Rabah explains, both poured
their wine into the barrel, the Rabbanan concede that no Eruv is needed,
then what are they arguing about, and what is the basis of their
(b) What is the technical difference between Eruv Chatzeros and Shituf
Mavu'os, and how is this based on the difference in their functions?
(c) How does Rav Yosef (who disagrees with Rabah), on the basis of that
distinction, explain the Machlokes between Rebbi Shimon ben Tada'i and the
(d) How does Rav Yosef prove his interpretation of Rebbi Shimon ben Tada'i
from Rav, who is quoted as ruling both like Rebbi Meir and like Rebbi
Shimon ben Tada'i? What does Rebbi Meir say?
(a) Abaye queries Rav Yosef's proof on the grounds that Rav would then
need to issue the same ruling twice.
Which of the two rulings would be
superfluous, and why is that?
(b) Why *does* Rav need to issue his second ruling 'Halachah ke'Ven
Tada'i'? And why does he need to issue two rulings at all? Why did he not
just rule like Rebbi Meir?
(a) Rebbi Meir holds that Eruv Chatzeros is confined to bread, whereas
Shituf Mavu'os should be made with wine.
May one use bread for a Shituf
(b) According to some, Rebbi Meir and the Rabbanan argue only when wine is
used for either the Eruv or the Shituf, but they agree that, if bread is
used, one Eruv will suffice for both the Mavoy and the Chatzer. Others say
that even the Rabbanan agree that, when wine is used, two Eruvin are
needed, and they only argue by bread.
What is then Rebbi Meir's reason
for requiring a separate Eruv for each?
(a) What is the Kashya on the Rabbanan from the words (of the Rabbanan in
our Mishnah) 'O Me'arvin, O Mishtatfin'? How does the Gemara initially
Answers to questions
(b) How does Rav Gidal quoting Rav interpret that phrase?
(c) Some say 'Halachah ke'Rebbi Meir', others, 'Minhag ke'Rebbi Meir', and
yet others 'Nahagu ke'Rebbi Meir'.
What is the difference between these
