prepared by Rabbi Eliezer Chrysler
Kollel Iyun Hadaf, Jerusalem
Previous dafEruvin 97
(a) The Gemara concludes that everyone agrees with Rebbi Elazar's Din
(that nobody would take the trouble to re-spin torn threads to attach to
the border of one's clothes.
In that case, why does Rebbi Yehudah forbid
carrying in new Tefilin (since, by the same token, no-one will take the
trouble to make an amulet that resembles Tefilin, either)?
(b) Do we have a proof from here that, regarding Tefilin, a bow is not
acceptable in lieu of a knot, because, if it were, why could one not make
a bow, according to Rebbi Yehudah?
(c) Since the type of knot required on Tefilin is 'Halachah le'Moshe
mi'Sinai', why do we need to say that Rebbi Yehudah forbids making a bow
because he considers it to be a knot (which is forbidden on Shabbos)?
Since without that, Tefilin require a proper knot 'Halachah le'Moshe
(d) From where do we know that the 'Daled' and the 'Yud' made in the
Tefilin straps, should be visible?
(a) Rav Chisda quoting Rav, says that someone who buys Tefilin wholesale
from an uncertified salesman, must examine three individual Tefilin before
the seller becomes certified. Which three Tefilin are referred to here,
and what will he be certified for?
(b) What will be the Din if he examines just three Tefilin Shel Yad or
three Tefilin Shel Rosh?
(c) When will the examination of three pieces (or even sets) of Tefilin
not be effective?
(a) So how will Rav interpret the Beraisa quoted by Rabah bar Shmuel
'bi'Tefilin, Bodek Shalosh Shel Yad ve'shel Rosh'?
(b) And how does he explain the Beraisa quoted by Rav Kahana 'bi'Tefilin,
Bodek Shetayim, Shel Yad ve'Shel Rosh'?
(c) If the author of this Beraisa is Rebbi, why does the Seifa say
've'Chen be'Tzeves ha'Sheni, ve'Chen be'Tzeves ha'Shelishi'? Why does the
third group not have a Chazakah after the first two?
(d) Then why does the Tana stop at Shelishi? Does that not suggest that
the three form a Chazakah, and that the fourth and the fifth batch do not
(a) 'Matz'an Tzevasin O Kerichos, Machshich Aleihen u'Mevi'an'.
the difference between 'Tzevasin' and 'Kerichos'?
(b) Why should he not take them in pair by pair, like in the Reisha?
(a) 'u've'Sakanah, Mechasan ve'Holech'.
Answers to questions
How do we reconcile our Mishnah
with the Beraisa, which says 'u've'Sakanah, Molichan Pachos Pachos me'Arba
(b) If our Mishnah is speaking about the danger of being discovered by
gentiles and killed, why does Rebbi Shimon say 'Nasnan la'Chaveiro' ...
Why should he endanger his life by doing this?
(c) Why does ...
- ... the Tana Kama prefer the method of carrying them less than four Amos at a time?
- ... Rebbi Shimon prefer the method of handing them to one's friend etc.?
(a) What does 've'Chen Be'no' mean? Why do they need to carry him?
(b) And why does the Tana add 'Afilu Hen Me'ah'? What is the Chidush?
(a) 'Rebbi Yehudah Omer, Nosen Adam Chavis la'Chaveiro, va'Chaveiro
la'Chaveiro' ... Does Rebbi Yehudah not agree with the Mishnah in
Beitzah 'ha'Beheimah ve'ha'Kelim ke'Raglei ha'Ba'alim'?
(b) How does Rebbi Yehudah advocate carrying the water?
(a) In what connection does Rebbi Yehudah say this in Beitzah?
(b) On what grounds does the Gemara reject the contention that water is
not Koneh Shevisah?
(c) So why *does* Rebbi Yehudah permit one person to carry someone else's
barrel of water?
(d) The source for such a Bitul (Tefeilah) is a Mishnah in Shabbos.
does the Mishnah say there?
(a) The Gemara queries the previous explanation, on the grounds that Rebbi
Yehudah in a Beraisa, explicitly permits the barrel of water by a Shayara
How does Rav Yosef therefore explain our Mishnah?
(b) Abaye reconciles the Mishnah with the Beraisa.
How does he do that?
(c) Rav Ashi establishes our Mishnah by both a barrel and water which are
How does he then explain the Amru Lo who argue with Rebbi
Yehudah, and say 'Lo Tehalech Zu Yoser me'Raglei Ba'aleha'?
(a) If someone is reading a Sefer (in the form of a scroll) and one end
rolls out of his hands on to the threshold of his house, our Mishnah
permits rolling it back.
Answers to questions
Why is that?
(b) What is the Din if the same thing happens when he is standing on the
roof of his house, and below, is a Reshus ha'Rabim?
(c) What does Rebbi Yehudah hold in this case?
(d) And what does Rebbi Shimon say?
