(a)What is 'a Muktzeh'?

(b)'Maschilin ba'Areimas ha'Teven, Aval Lo be'Etzim she'be'Muktzeh'. 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 Muktzeh. How will he explain ...

1. ... the Seifa of the Mishnah ('Aval Lo be'Eitzim she'be'Muktzeh')?

2. ... the Reisha ('Maschilin 'ba'Areimas ha'Teven')?


(a)A Muktzeh - is a storehouse behind the house where they stored wood.

(b)If the author of the Mishnah in Beitzah 'Maschilin ba'Areimas ha'Teven' would be Rebbi Yehudah - then we would have to establish it by straw that began to smell already before Shabbos and that was no longer fit for animals, only to be used as fuel.

(c)According to Rebbi Yochanan ...

1. ... 'Aval Lo be'Eitzim she'be'Muktzeh' - speaks by types of cedar-wood, which are initially designated for building (and not for firewood). Consequently, they are Muktzeh Machmas Chesaron Kis - a category of Muktzeh with which even Rebbi Shimon agrees.

2. ... 'Maschilin 'ba'Areimas ha'Teven' - speaks even if the straw was fit for animals before Shabbos entered.


(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 Muktzeh?


(a)It was common to water the animals before Shechting them, to facilitate the subsequent skinning process.

(b)'Midbari'os' - are animals that would graze outside the Techum, but would return overnight; 'Baysos' would graze inside the Techum, too - The former are Muktzeh, because the owners took their minds off them.

(c)The author of this Mishnah in Beitzah - must be Rebbi Yehudah, who holds of Muktzeh.

(d)The Mishnah in Beitzah, which forbids chopping up beams that were designated for building purposes, and a beam which broke on Yom-Tov - may well be a Stam Mishnah (like which Rebbi Yochanan always concurs); however, Rebbi Yochanan has another Stam Mishnah (above on Daf 143a), which holds like Rebbi Shimon. The Mishnah there quotes Beis Shamai as saying that one may remove the bones and the shells from the table, and Beis Hillel disagrees. Rebbi Yochanan agrees with Rav Nachman, who inverts the opinions. According to him, it is Beis Hillel who permits the removal of bones and shells from the table, and Beis Shamai who forbids it - and Beis Hillel is considered a Stam Mishnah (even when they argue with Beis Shamai).


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

(b)Which kind of Muktzeh 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)?


(a)One Amora rules like Rebbi Yehudah by 'Muktzeh Machmas Mi'us' - the other, by 'Muktzeh Machmas Isur' (i.e. a lamp which was lit for that Shabbos).

(b)Rebbi Shimon agrees - that 'Muktzeh Machmas Chesaron Kis' is Muktzeh.

(c)The two examples of 'Muktzeh Machmas Chesaron Kis' listed by the Mishnah - are a large saw and the peg (coulter) of a plow.


(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'Mikveh'?


(a)'Mefirin Nedarim' - refers to a husband (or a father) nullifying his wife's (or daughter's) vows; whereas 've'Nish'alin li'Nedarim' - refers to a Rav (who is an expert, or three individuals) nullifying anybody's vows.

(b)A Rav may nullify vows that concern (Oneg) Shabbos.


1. ...'Pokekin es ha'Ma'or' - means that one is permitted to put a window-stopper (such as shutters) in place on Shabbos.

2. ... 'Modedin es ha'Matlis' - means to measure a piece of cloth to see whether it is three by three finger-breadths (in which case it will be fit to be Mekabel Tum'ah), or not.

3. ... 'Modedin es ha'Mikveh' - means to measure a Mikveh to see whether it is three Amos deep and fills an area of an Amah by an Amah, or not.


(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?


(a)In the days of Rebbi Tzadok's father and of Aba Shaul ben Botnis - they stopped up the window with an earthenware pitcher and tied a small earthenware jar (one Tefach wide) with a reed (to know whether or not, there was an opening of a Tefach in the crack of the barrel - which we will discuss later).

(b)We learn from this episode - that one is permitted to stop up a window (to add to a casual Ohel), to measure (for a matter of Mitzvah) and to tie a (temporary) knot on Shabbos.


(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?


(a)A husband may be permitted to nullify even his wife's vows which are not necessary for Shabbos - because he may possibly only be permitted to nullify them until nightfall, in which case, nullifying the vow cannot be delayed.

(b)If 'le'Tzorech Shabbos' in our Mishnah also refers to Hafaras Nedarim - this signifies that Hafaras Nedarim may be performed for a full twenty-four hours (and not just until night-fall), thereby giving the husband so many hours after Shabbos to nullify the vow.

(c)If the wife made a vow on Friday night - then he has the rest of the night and the entire day in which to nullify it (that is what the Mishnah means by 'Lehakel'); whereas if she made the vow just before nightfall on Shabbos afternoon - he only has the few remaining minutes until nightfall (Lehachmir).

Note: We are assuming that the husband heard his wife made the vow. Otherwise, he has until nightfall or twenty-four hours from the time that he hears about it.

(d)The Gemara concludes - that whether the husband has only until nightfall to nullify his wife's vows, or whether he has a full twenty-four hours, is in fact a Machlokes Tana'im; the Tana Kama (of the Beraisa) gives him only until nightfall, whereas, according to Rebbi Yossi b'Rebbi Yehudah and Rebbi Elazar b'Rebbi Shimon, he has a full twenty-four hours.


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


(a)A Rav is permitted to nullify vows on Shabbos which pertain to Shabbos, even though there was time to nullify them before Shabbos came in.


(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 inquiry?

(c)Why did they stop up the windows?

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


(a)The body was lying underneath a barrel on a narrow path between two houses. The barrel filled the space between the two houses.

(b)They were trying to discover whether the crack in the barrel was one Tefach wide. If it was, then, when the person died, the Tum'ah would simply travel up through the crack in the barrel, and not enter the houses at the side - via the windows; if not, it would indeed enter the houses, and render Tamei whoever and whatever was inside the house.

(c)They stopped up the windows - just in case the man died, and the crack in the barrel turned out to be less than a Tefach wide.

(d)They used specifically a reed to tie to the pitcher - because a reed is animal food, which one would not be Mevatel there permanently (since a permanent knot is certainly forbidden) - and besides, a reed will become brittle when it dries and just snap, so that anyway, a knot in a reed is never permanent.


(a)Is one permitted to measure on Shabbos?


(a)Measuring on Shabbos is permitted, provided it is for a Devar Mitzvah (placing a stopper in a window is permitted, irrespective of whether it is for a Devar Mitzvah or not - see Tosfos DH 'Medidah'. As far as tying a knot is concerned, see Tosfos Yom-Tov DH 'u'Modedin')
