12TH CYCLE DEDICATIONS:
 
ERUVIN 49 (21 Marcheshvan) - Dedicated l'Iluy Nishmat Harav Moshe Zrihen ben Rachel, Dayan in Marrakech, Morocco, by Dr. Alain Bitton of Geneva, Switzerland.

1)

(a)What is the Din of a courtyard that opens into two Mavo'os ...

1. ... if they did not both make an Eruv?

2. ... if they did?

(b)In the former case, under what circumstances will the residents of one of the Mavo'os be permitted to carry - in spite of the Chatzer that opens into it?

(c)How will the residents of the Mavoy through which the residents of the courtyard are accustomed to walk, be permitted to carry in their own courtyard, in spite of the fact that they did not make an Eruv together?

(d)In which connection is Shmuel quoted as saying 'Kegon Zu, Kofin al Midas Sedom'?

2)

(a)Why does Shmuel invalidate the Eruv of someone who is fussy that his bread should not be eaten by any of the participants?

(b)What were the men of Vardina known for?

(c)In which case will Beis Hillel, who normally validate an Eruv that is placed in two receptacles, agree that it is Pasul?

3)

(a)Why does Shmuel need to rule both by someone who is fussy about his Eruv being eaten, and by someone who is fussy about placing his Eruv in the same receptacle as the others', when both seem to stem from the fact that it is not an 'Eruv'?

(b)How do we reconcile Shmuel, who invalidates the Eruv of someone who places his Eruv in a separate receptacle, with his own ruling, exempting the person in whose house the Eruv (consisting of bread that was collected from each of the participants) is placed, from placing his bread?

(c)What did the Gemara initially think that Shmuel meant that prompted the question?

4)

(a)According to Shmuel, who holds 'Eruv Mishum Kinyan', why can one not use money?

(b)What does Rabah hold in this matter?

(c)One difference between the two opinions is 'Kli'. What does 'Me'arvin bi'Chli mean?

(d)What are the other two differences?

5)

(a)The Beraisa permits one person to place his own Eruv on behalf of the five who are participating in an Eruv. Why do we not say that the Eruv only acquires on his behalf (according to Shmuel) - but not on behalf of the other participants? And why do we not say (according to Rabah) that only he becomes a co-resident in the Chatzer, but not all the others on whose behalf he is acting?

(b)What is the final ruling in this matter - regarding the middle Chatzer combining with the two outer ones?

6)

(a)What can a traveler do, as Shabbos enters, to enable him to walk two thousand Amos until a certain point, and from there, another two thousand Amos to his house - on Shabbos?

(b)How does he then measure this two thousand Amos, according to ...

1. ... Rebbi Chanina ben Antignos?

2. ... the Chachamim?

(c)According to Rebbi Yehudah, why did Chazal institute the concept of an Eruv using bread?

(d)According to Rebbi Meir, why did they institute the concept of Eruv on foot?

7)

(a)Rav interprets the 'Lo Amar Klum' in the Reisha of our Mishnah (when he saw a tree and said 'Shevisasi Tachteha') to mean that he has nothing. Why is that?

(b)How does Shmuel explain 'Lo Amar Klum' (according to Rashi's first Lashon)?

(c)What is the meaning of 've'Na'aseh Tachtav shel Ilan Chamar Gamal'?

8)

(a)Rashi gives a second interpretation of 'Lo Amar Klum' according to Shmuel, which he then proceeds to discard. What is it?

9)

(a)Why does the Gemara not probe Shmuel's reason in Rebbi Meir (like it does for Rav's)?

(b)What are the two possible reasons for Rav?

(c)What is the difference between them?
