(a)Rav Papa asks whether the Shi'ur of a Koseves ha'Gasah (a large date) includes the pit or not. If it does not, how will we explain the Mishnah, which explicitly writes 'Kamoha u'ki'Gerinasah'?

(b)Rav Ashi asked whether the Mishnah in Ohalos 'Etzem ki'Se'orah' (the Shi'ur that a bone from a dead person is Metamei) includes the shell of the barley, or not. What second She'eilah does he ask?

(c)Why does Rav Ashi not agree with Rav Papa's She'eilah? Which side of the She'eilah does he take for granted?

(d)Rav Papa does not agree with Rav Ashi's She'eilah. According to him, when is a barley grain called ...

1. ... a 'Shibo'les'?

2. ... an 'Ushla' (or a 'Chushla')?

(a)Rav Papa asks whether the Shi'ur of a Koseves ha'Gasah (a large date) includes the pit or not. If it does not - we will explain the Mishnah, which explicitly writes 'Kamoha u'ki'Gerinasah', as if it would have written 'Kamoha O ki'Gerinasah' (see Tosfos DH 'Koseves).

(b)Rav Ashi asked whether the Mishnah in Ohalos 'Etzem ki'Se'orah' (the Shi'ur of a bone from a dead person that is Metamei) includes the shell of the barley, or not. He also asks whether the barley is a wet one or a dry one.

(c)Rav Ashi does not agree with Rav Papa's She'eilah. He takes for granted that the Tana means a date with the pit - because the Mishnah says 'Koseves ha'Gasah', indicating that it must be as large as possible.

(d)Rav Papa does not agree with Rav Ashi's She'eilah. According to him, a barley grain is called ...

1. ... a 'Shibo'les' - once it becomes dry.

2. ... an 'Ushla' (or a 'Chushla') - once it sheds its shell. Consequently, 'Etzem ki'Se'orah' must be referring to a wet grain with its shell still intact.

(a)According to Rabah quoting Rav Yehudah, is a Koseves ha'Gasah more than a k'Beitzah, or less?

(b)Either way, why did Chazal give that Shi'ur for Yom Kippur, and not a k'Zayis?

(c)What did Raban Gamliel say when they brought him a bucket of water and two large dates on Sukos? Was this obligatory?

(d)Which three leniencies did Rebbi Tzadok practice when they gave him less than a k'Beitzah of food on Sukos?

2)

(a)According to Rabah quoting Rav Yehudah, a Koseves ha'Gasah is more than a k'Beitzah.

(b)Chazal gave that Shi'ur for Yom Kippur, and not a k'Zayis - because whereas by other Isurim, the Torah uses a Lashon of Achilah, by Yom Kippur, it writes "Asher Lo Se'uneh", and, as long as a person's hunger is not stilled (a situation that requires a Koseves ha'Gasah), it is called 'Inuy'.

(c)When they brought Raban Gamliel a bucket of water and two large dates on Sukos, he told them to take them up to the Sukah - not because it was obligatory, explains the Beraisa, but because he wanted to take a stringent line (to go beyond the letter of the law).

(d)When they gave Rebbi Tzadok less than a k'Beitzah of food on Sukos - he wrapped his hands in a cloth (to avoid having to wash them), he ate them outside the Sukah, and he did not Bentch (recite after-blessing) after eating them (see Tosfos DH 've'Lo').

3)

(a)What can we deduce from Rebbi Tzadok (in the previous question) - with regard to the Shi'ur of food that requires a Sukah?

(b)What is now the problem with Rav Yehudah (who learnt earlier that a Koseves ha'Gasah with its pit is more than a k'Beitzah) from Raban Gamliel? How do we know that two dates are less than a k'Beitzah?

(c)How does Rebbi Yirmeyahu answer this Kashya?

(d)What common saying derives from what Rebbi Yirmeyahu just said?

3)

(a)We can deduce from Rebbi Tzadok (in the previous question) - that a k'Beitzah of food requires Sukah.

(b)We see from Raban Gamliel that two large dates are less than a k'Beitzah -since the Beraisa said that Raban Gamliel was not obligated to eat them in the Sukah, and we just deduced from Rebbi Tzadok that a k'Beitzah is Chayav Sukah.

(c)Rebbi Yirmeyahu answers this Kashya - by making a distinction between two large dates without the pits (which are indeed less than a k'Beitzah), and one large date with its pit (which is more). In other words, the stone of a large date is larger than the date itself.

(d)The common saying that derives from what Rebbi Yirmeyahu just said - is 'Two Kabin of dates is equivalent to one Kav of pits'.

4)

(a)Rava dismisses the above Kashya outright. According to him, two dates are more than a k'Beitzah. In that case, why did the Tana say that they did not require a Sukah?

(b)How will Rava explain Rebbi, who said in a Beraisa that they ate figs and grapes in front of Rebbi Elazar ben Shamu'a 'Achilas Ara'i' (casually - less than a k'Beitzah) outside the Sukah - implying that to do so 'Achilas Keva' (more than a k'Beitzah) would have been forbidden - even though figs and grapes too, are fruit?

(c)Alternatively, the Beraisa speaks when they ate a full Shi'ur of fruit (an 'Achilas Keva'). Then why did Rebbi mention 'Achilas Ara'i'?

4)

(a)Rava dismisses the above Kashya outright. According to him, two dates are more than a k'Beitzah - The reason that the Tana said that they did not require a Sukah, is because dates are a fruit, and fruit does not require a Sukah (only bread or cake, which constitute a fixed meal).

(b)We amend Rebbi, who said in a Beraisa that they ate figs and grapes in front of Rebbi Elazar ben Shamu'a 'Achilas Ara'i' - to 'ka'Achilas Ara'i', meaning that however much they would have eaten, it would have been Achilas Ara'i, because fruit is always Achilas Ara'i.

(c)Alternatively, the Beraisa speaks when they ate a full Shi'ur of fruit (an 'Achilas Keva') - and the Achilas Ara'i that Rebbi mentioned refers to the bread that they ate with it (i.e. less than a k'Beitzah).

5)

(a)How do we try to prove Rava right from the Mishnah in Sukah, which says that, according to Rebbi Eliezer (who requires fourteen meals in the Sukah), one can make up those meals with 'Minei Targima'? What do we presume 'Minei Targima' means to mean?

(b)How do we refute this proof by redefining 'Targima'?

(c)How do we then refute it - even assuming that 'Targima' does not mean fruit? Why might the Tana have omitted fruit, even if fruit does require Sukah?

5)

(a)We try to prove Rava right from the Mishnah in Sukah, which says that, according to Rebbi Eliezer (who requires fourteen meals in the Sukah), one can make up those meals with 'Minei Targima' - which we presume to mean a condiment (i.e. something that is normally eaten together with bread as part of the meal).

(b)We refute this proof by redefining 'Targima' as fruit.

(c)We then refute it - even assuming that 'Targima' means condiments - on the grounds that the Tana suggests condiments for people who live in a place where fruit is rare.

6)

(a)Why do Beis Shamai hold that whereas, regarding 'Bal Yera'eh' and 'Bal Yimatzei', the Shi'ur for yeast is a k'Zayis, the Shi'ur for Chametz is a Koseves? Why should Chametz and yeast have different Shiurim?

(b)Why can we not say that the Shi'ur for Chametz is a k'Zayis and the Shi'ur for yeast, less than a k'Zayis?

(c)How does Rav Zevid prove from here that a Koseves ha'Gasah is less than a k'Beitzah?

(d)We refute this proof by pointing out that Beis Shamai refers to an ordinary Koseves, which is equal to a k'Beitzah; whereas a Koseves ha'Gasah is indeed larger than a k'Beitzah (as Rav Yehudah contends). What is the Gemara's second answer?

6)

(a)Beis Shamai holds that whereas, regarding 'Bal Yera'eh' and 'Bal Yimatzei', the Shi'ur for yeast is a k'Zayis, the Shi'ur for Chametz is a Koseves - because had the Torah wanted them to have the same Shi'ur, it would have omitted yeast (which makes other foods Chametz), which we would then have learnt from a Kal va'Chomer from Chametz (which does not).

(b)It is illogical to say that the Shi'ur for Chametz is a k'Zayis and the Shi'ur for yeast, less than a k'Zayis - since that would make the Lav of Bal Yera'eh (which is basically to avoid the Isur of Achilah) more stringent than Achilah itself, whose Shi'ur is a k'Zayis.

(c)Now if the Shi'ur of a Koseves ha'Gasah was more than a k'Beitzah (like the opinion of Rav Yehudah), argues Rav Zevid, then why does Beis Shamai, when giving the Shi'ur for Chametz, jump from a k'Zayis to a Koseves? Why does he not give the Shi'ur as a k'Beitzah, which is also more than a k'Zayis? And even if they are equal, why do they mention a Koseves and not (the more common) k'Beitzah? Clearly therefore, a Koseves is the Shi'ur after a k'Zayis, and not a k'Beitzah!

(d)We refute this proof by pointing out that Beis Shamai refers to an ordinary Koseves, which is equal to a k'Beitzah; whereas a large Koseves (i.e. a Koseves ha'Gasah) is indeed larger than a k'Beitzah (as Rav Yehudah contends). And besides, says the Gemara, even if a Koseves ha'Gasah is equivalent to a k'Beitzah, the Tana mentions one of two examples, and is not fussy which one. (Note: It is unclear however, how both answers appear to dismiss the second Kashya in c.)

(a)According to Rebbi Meir, one needs to eat a k'Zayis of bread in order to Bentch. What does Rebbi Yehudah hold?

(b)Both of them derive their opinions from the Pasuk in Ekev "v'Achalta v'Sa'va'ta u'Verachta ... " How does Rebbi Meir interpret ...

1. ... "v'Achalta"?

2. ... "v'Sava'ta"?

(c)How does Rebbi Yehudah interpret these two words?

(d)How does Rebbi Zevid derive from here that a Koseves ha'Gasah must be less than a k'Beitzah? Which comes first, 'Meyasva' or 'Sevu'i?

7)

(a)According to Rebbi Meir, one needs to eat a k'Zayis of bread in order to Bentch; according to Rebbi Yehudah, it is a k'Beitzah - enough to be satisfied.

(b)Both of them derive their opinions from the Pasuk in Ekev "v'Achalta v'Savata u'Verachta ... ". Rebbi Meir interprets ...

1. ... "v'Achalta" - to mean eating (a k'Zayis).

2. ... "v'Savata" - as drinking (meaning that one needs to eat and drink in order to Bentch).

(c)According to Rebbi Yehudah, "v'Achalta" means to eat (which normally implies a k'Zayis), and "v'Savata", to be satisfied (i.e. a k'Beitzah).

(d)Rebbi Zevid derives from here that a Koseves ha'Gasah must be less than a k'Beitzah - because otherwise, if a k'Beitzah satisfies a person ('Sevu'i'), then it must surely still his hunger ('Meyasva')! It can only be, he proves, that a Koseves ha'Gasah stills a person's hunger without satisfying, and a k'Beitzah even satisfies.
