ERUVIN 31-35 - have been dedicated by Mrs. Rita Grunberger of Queens, N.Y.,
in loving memory of her late husband, Yitzchok Yakov ben Eliyahu Grunberger,
whose Yahrzeit is the 10th of Sivan.

1)
(a) In a Beraisa, Rebbi Yehudah permits placing Terumah Tehorah on a grave
for a Kohen Tahor.
Why do both the Kohen and the Terumah need to be Tahor?
(b) How can Rebbi Yehudah permit placing Terumah on a grave? Why does the
Terumah not become Tamei?
(c) How was the loaf carried there? Why does the vessel which contains it
not become Tamei Mes and transmit Tum'ah to the Kohen?
2)
(a) The Gemara eventually establishes the Beraisa when he is carrying the
food on the thin point of the straight wooden vessel, which is less than one
Tefach thick. What does this mean? What would the Din be otherwise?
(b) Why do the Rabbanan then disagree with Rebbi Yehudah, to prohibit making
an Eruv with Tahor Terumah for a Tahor Kohen - even in a case where there is
only one grave, where the Kohen can perhaps avoid coming into contact
with the grave?
(c) Does this mean that Rava, who holds 'Mitzvos La'av Lehanos Nitnu',
follows the opinion of Rebbi Yehudah, since one is only permitted to make an
Eruv for a D'var Mitzvah, yet the Rabbanan forbid it?
(d) According to this, the Rabbanan's reason applies just as much to an Eruv
of Chulin for a Yisrael.
Why then, does the Tana mention specifically
Terumah and a Kohen?
3)
We just established that, according to the Rabbanan, one is permitted to
make an Eruv for a D'var ha'Reshus, does this mean that Rav Yosef, who holds
that one may only make an Eruv for a D'var Mitzvah, follows the opinion of
Rebbi Yehudah?
4)
(a) Why is it permitted to make an Eruv with Demai, which still requires to
be Ma'asered?
(b) Is there any Tana who forbids it?
Answers to questions
31b---------------------------------------31b
5)
(a) The Mishnah also permits Ma'aser Rishon, whose Terumah was taken, to be
used for an Eruv.
What is the Chidush?
(b) What do we learn from the Pasuk in Korach "mi'*Kol* Ma'asroseichem
Tarimu es Kol Terumas Hashem"?
(c) The stage at which corn becomes obligated to be Ma'asered is called
'Idgan'.
What does 'Idgan' mean?
6)
(a) What is the Mishnah telling us when it says that Ma'aser Sheni and
Hekdesh that have been redeemed may be used for en Eruv? Is that not
obvious?
(b) And what is the Mishnah telling us when it says that the following may
not be redeemed:
- Tevel?
- Ma'aser Rishon whose Terumah has not been taken?
- Ma'aser Sheni and Hekdesh that have not been redeemed?
7)
(a) May one send one's Eruv Techumin with a Cheresh, Shoteh or Katan?
(b) An Eruv may also not be sent with someone who does not agree with the
concept of Eruv.
To whom does this refer?
(c) How do we reconcile this Mishnah with Rav Huna, who permits a Katan to
collect the food for an Eruv?
8)
(a) We establish our Mishnah, which permits even using a Kuti for Eruv
Techumin, provided the Kuti gives the food to someone else (who puts it in
place)?
Which condition must be met?
(b) How do we know that the man to whom the Kuti handed the Eruv carried out
his Shelichus?
