ERUVIN 86 - was generously dedicated by an anonymous donor in Los Angeles
in honor of his son, Sam, who lives and teaches in Yerushalayim.
(a) According to Rebbi Meir, both a Jew and a gentile who are away for
Shabbos forbid the remaining residents of the Chatzer to carry. Rebbi
Yehudah holds that they do not.
What is the basis of their Machlokes?
(b) Rebbi Yossi differentiates between a Jew and a gentile.
What does he
say? Like whom does he hold in principle?
(c) The Halachah however, is like Rebbi Shimon, in whose opinion even a
Jew who went to stay with his daughter in the same town, will not forbid
the other residents to carry.
Why does he specifically refer to 'his
(a) In order to draw water from a Uka that divides between two courtyards,
the Tana Kama requires a Mechitzah of ten Tefachim, either below or
What does 'Mitoch Ugno' mean?
(b) According to Rebbi Shimon ben Gamliel, the location of the Mechitzah
is a Machlokes between Beis Shamai and Beis Hillel.
What do *they* say?
(c) Rebbi Yehudah is even more lenient than the Tana Kama.
What does he
(a) Rav Huna explains the 'Milematah' of Beis Shamai to mean below the top
of the Uka (but above the level of the water), and the 'Milema'alah' of
Beis Hillel to mean at the top of the Uka (but inside it).
How does Rav
Yehudah explain the Machlokes?
(b) Why does Rav Yehudah reject Rav Huna's explanation of Beis Shamai's
(c) How does this argument boomerang back on him?
(d) How does the Gemara resolve that?
(a) Why does Rav Yehudah reject Rav Huna's explanation of 'Lema'alah
Mamash' (in Beis Hillel)?
(b) And how does this argument boomerang back on him?
(c) So what is his real reason for doing so?
(a) Rav Yehudah permits one to carry underneath a beam of four Tefachim
wide that stretches across the entrance of a ruin.
Answers to questions
(b) The Halachah is not like him. It is however, like Rav Nachman quoting
Rabah bar Avuha, who permits the same beam that is suspended over a Uka of
How does this vindicate Rav Huna in the previous question, and
prove Rav Yehudah wrong?
(c) Is a suspended Mechitzah also effective in a ruin or in a courtyard?
(a) What must be the dimensions of a wall that starts from the ground
upwards, in order to be a Kasher Mechitzah?
(b) The Tana Kama of the Mishnah in Succah requires a wall that starts
from the top downwards, to reach within three Tefachim of the ground.
What does Rebbi Yossi hold in this regard?
(c) Is Rebbi Yehudah's Din in our Mishnah (who permits a Mechitzah that is
suspended above the walls of the Uka and does not even reach them)
confined to water?
(d) He appears to hold like Rebbi Yossi, but the Gemara concludes that the
two are not necessarily connected.
Why might ...
- ... Rebbi Yehudah's opinion be confined to the Din of Eruv, but not to that of Succah, like Rebbi Yossi?
- ... Rebbi Yossi's opinion be confined to the Din of Succah, but not to that of Shabbos, like Rebbi Yehudah?
(a) If, as we just suggested, Rebbi Yossi will not apply the Din of
Mechitzah Teluyah on Shabbos, then who was it who permitted a Mechitzah
Teluyah one Shabbos in Tzipori, Rebbi Yossi's town?
Answers to questions
(b) What happened there?
(c) On what grounds does the Gemara reject the initial text of 'Parsu
Sadin al ha'Amudin'?
