(a) How does the Gemara know that when Rebbi Yochanan said his K'lal ('Ein
Lemedin min ha'Kelalos, va'Afilu be'Makom she'Ne'emar Bo Chutz'), he was not
referring directly to our Mishnah?
(b) In spite of the principle that women are exempt from Mitzvos Asei which
are time-related, they are Chayavos in 'Matzah, Simchah and Hakhel'.
where do we know each of these?
(c) On the other hand, they are Peturos from 'Talmud-Torah, Piryah ve'Rivyah
and Pidyon ha'Ben', even though these are not time-related.
From where do
we know each of these?
(a) What is the difference between something which a Zav carries, and
something which carries a Zav, according to the Mishnah in Zavin?
(b) What does the Mishnah in Zavin omit, when it presents the K'lal 'Kol
she'ha'Zav Nisa Alav Chutz min ha'Ra'uy le'Mishkav u'Moshav?
(c) What is the exception to the K'lal in our Mishnah of 'ha'Kol Nikach
be'Kesef ma'aser Chutz min ha'Mayim u'min 'ha'Melach'?
(a) We have learned in our Mishnah that both water and salt are not
eligible for use with regard to Eruvin, nor can they be purchased with the
money of Ma'aser Sheni. Rebbi Elazar and Rebbi Yossi b'Rebbi Chanina agree
that salt-water may be used for *Eruvin*.
Why is that?
(b) Why does one of them forbid even salt-water to be purchased with
(a) Rebbi Yehudah ben Gadish testified before Rebbi Eliezer that in his
father's house, they used to purchase fish-juice with Ma'aser-Sheni money.
Answers to questions
What did Rebbi Eliezer say to him?
(b) How does this present Rav Yitzchak, who specifically quoted the Beraisa
which permits salt-water, in connection with Ma'aser, with a problem?
(c) How does Rav Yosef resolve this problem?
(a) Under which conditions may one buy water and salt together with oil? Why
does one need to mention the water and the salt at all?
(b) What does ben Bag Bag learn from ...
- ... "ba'Bakar" (written in Re'ei in connection with Ma'aser-Sheni)?
- ... "u'va'Tzon"?
- ... "u'va'Yayin"?
- ... "u'va'Shechar"?
(a) Now that the Torah writes ...
(b) Rebbi Yochanan has a problem as to why the Torah finds it necessary to
- ... "Shechar", why does it need to add "Yayin"?
- ... "Yayin", why does it need to write "Tzon"?
Why can we not say that, had Bakar been omitted, we would have
included the *skin* from "Tzon", but not the *wool*?
(c) What did Rebbi Yochanan say he would do for anyone who would explain to
him why the Torah wrote 'Bakar'?
(a) The Tana in a Beraisa expounding on a Pasuk in Re'ei, explains
"ve'Nasata ha'Kesef be'Chol Asher Te'aveh Nafshecha" - K'lal, "ba'Bakar
u'va'Tzon, u'va'Yayin u'va'Shechar" - P'rat, "ba'Chol Asher Te'aveh
Nafshecha" - K'lal. He maintains that we learn 'P'ri mi'P'ri ve'Gidulei
Karka'. What does this mean and what does it come to exclude?
Answers to questions
(b) Rebbi Yehudah ben Gadish (quoted at the end of the previous Amud),and
Rebbi Eliezer both agree that fish may be bought with Ma'aser-Sheni money.
On what basis do they argue with the Tana of this Beraisa?
(c) Initially, the Gemara thinks that Abaye explains that according to a
third Tana, who learns a 'K'lal u'F'rat u'Chelal', but with the formula
'V'lad Velados ha'Aretz', fish are included in the 'K'lal u'Frat u'Che'lal'.
Why is this problematic from another statement of Abaye, where he says that
one receives four Malkus for eating a Putisa (a type of water-insect), five
for an ant and six for a hornet.
How many Malkus should one receive for
eating a Putisa?
(d) How does Ravina then explain the Machlokes between the two ways of
learning the 'K'lal u'F'rat u'Chelal'.
