Eruvin 31

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.


(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?

(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?


(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



(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?

(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:

  1. Tevel?
  2. Ma'aser Rishon whose Terumah has not been taken?
  3. Ma'aser Sheni and Hekdesh that have not been redeemed?
(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?

(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?
