REVIEW QUESTIONS ON GEMARA AND RASHI

prepared by Rabbi Eliezer Chrysler

Previous daf

Shabbos 157

1)

(a) What is 'a Muktzah'?

(b) 'Maschilin ba'Areimas ha'Teven, Aval Lo be'Eitzim she'be'Muktzah'. If the author of this Stam Mishnah in Beitzah would be Rebbi Yehudah, how would we explain the Reisha? Since when is straw designated for firewood and not for animals?

(c) Rebbi Yochanan always rules like a Stam Mishnah, but he also rules like Rebbi Shimon with regard to Muktzah.
How will he explain ...

  1. ... the Seifa of the Mishnah ('Aval Lo be'Eitzim she'be'Muktzah')?
  2. ... the Reisha ('Maschilin 'ba'Areimas ha'Teven')?
2)
(a) 'Ein Mashkin ve'Shochtin es ha'Midbari'os, Aval Mashkin ve'Shochtin es ha'Baysos'.
What does 'Mashkin' mean?

(b) What is the difference between Midbari'os and Baysos, and why may one not Shecht Midbari'os on Yom-Tov?

(c) Who must be the author of this Stam Mishnah in Beitzah?

(d) How can we now reconcile Rebbi Yochanan's principle Halachah ki'Stam Mishnah with his ruling like Rebbi Shimon by Muktzah?

3)
(a) Rav Acha and Ravina both rule like Rebbi Shimon except for one kind of Muktzah. One says except for 'Muktzah Machmas Mi'us'.
What does the other one say?

(b) Which kind of Muktzah does Rebbi Shimon himself concede?

(c) Which two vessels does the Mishnah (on 123b) list under this category (although, in spite of the exclusive terminology used by the Gemara, they are no more than examples)?

4)
(a) 'Mefirin Nedarim, ve'Nish'alin li'Nedarim ... '. What is the difference between 'Mefirin' and 'Nish'alin'?

(b) Which kind of vows may a Rav nullify on Shabbos?

(c) What is the meaning of ...

  1. ...'Pokekin es ha'Ma'or'?
  2. ... 'Modedin es ha'Matlis'?
  3. ... 'Modedin es ha'Mikvah'?
5)
(a) What did they do in the days of Rebbi Tzadok's father and of Aba Shaul ben Botnis?

(b) Which three Chidushim did 'they learn' from that incident?

6)
(a) Since a Rav may nullify only Nedarim which are necessary for Shabbos, why might a husband be permitted to nullify even Nedarim of his wife which are *not*?

(b) In the second version of the Sha'aleh, why does the Gemara think that 'le'Tzorech Shabbos' in our Mishnah also refers to Hafaras Nedarim of the husband? What does this signify?

(c) One Beraisa rules that a husband may only nullify vows which are le'Tzorech ha'Shabbos, proving that Hafaras Nedarim is me'Es le'Es. The Mishnah in Nedarim however (which clearly holds that Hafaras Nedarim is only valid until night-fall) writes 'Hafaras Nedarim Kol ha'Yom, ve'Yesh be'Davar Lehakel u'Lehachmir'.
What does this mean? When is it Lehakel, and when is it Lehachmir?

(d) What is the Gemara's conclusion? Is Hafaras Nedarim strictly until nightfall, or does the husband have twenty-four hours in which to be Mefer?

7) May a Rav nullify Nedarim on Shabbos which pertain to Shabbos, if there was time to nullify them *before* Shabbos came in?

8)

(a) 'They stopped up the window with a small clay jar, and tied a pitcher (which was one Tefach wide) with a reed and lowered it into the crack in the barrel' (before the person lying in the narrow path, died).
Where was the body lying?

(b) What were they trying to discover, and what were the ramifications of the outcome of their enquiry?

(c) Why did they stop up the windows?

(d) Why did they use specifically a reed to tie to the pitcher?

9) Is one permitted to measure on Shabbos?
