(a) What do Bei Rav in the name of Rav mean when they say (in connection
with Niguv) 'Tarti T'las'? When will 'two' suffice', and when does Rav
(b) By the same token, what does Shmuel mean when he says 'T'las, Arba'?
(c) What is the basic Machlokes between Rav and Shmuel?
(d) Why does Shmuel ignore the 'Mayim' that one inevitably ends up with?
(a) That was how they cited the Machlokes in Sura. In Pumbedisa, Bei Rav in
the name of Rav said 'T'las Arba'.
What did Shmuel then say?
(b) How will we now explain ...
(c) What is then the basis of the two opinions? Are Rav and Shmuel really
- ... Rav's opinion?
- ... Shmuel's opinion?
(a) Alternatively, it is Rav and Shmuel who argue in both Leshonos, whereas
the two Leshonos don't (this is the explanation of Rashi's father, whereas
the first explanation is that of Rashi's Rebbe). In that case, what do Bei
Rav in the name of Rav mean when they say (in connection with Niguv) 'Tarti
T'las'? Which one speaks 'bi'Retivta', and which 'be'Yabeshta'?
(b) With which of these does Shmuel ...
(c) If that is what they said in Sura, what did they mean when they said
'T'las ve'Arba' and 'Arba ve'Chameish' in Pumbedisa?
- ... agree?
- ... argue?
(d) Why do we prefer the second Lashon? What is the problem with the Lashon
of Sura, according to the first explanation?
(a) They asked Rebbi Avahu how one Kashers or purifies 'Gurgi', a sort of
lattice-work which covers and holds together the grapes beneath the beam in
What else might 'Gurgi' mean?
(b) In reply, Rebbi Avahu cited a Beraisa which discusses the purification
of wine and olive presses. The Tana requires the beams, the tubs and the
brooms to be washed.
What sort of brooms is he talking about? What were
they used for?
(c) What big Chidush can we learn from the fact that Rebbi Avahu resolved
the She'eilah that was put to him, from this Beraisa?
(a) What does the Tana require for baskets made of ...
(b) Seeing as the wine season generally occurs once a year, what is the
difference between the Tana Kama and Raban Shimon ben Gamliel, who says
'from one pressing to the next'?
- ... sticks or canvas (or flax)?
- ... various kinds of rushes? Why the difference?
(c) Rebbi Yossi gives a totally different Shiur. What does he say?
(d) He prescribes leaving them there for an Onah, adding that this Din
applies to Taharos just as it applies to Yayin Nesech.
How do we amend
this statement? Why is it necessary to amend it?
(a) Rebbi Chiya bar Aba Amar Rebbi Yochanan defines 'Onah' as a day or a
What does Rebbi Chana She'inah (or Rebbi Chana bar She'inah) Amar
... Rebbi Yochanan say?
(b) What do we mean when we say that the two opinions do not argue?
(a) According to Rav Yehudah, Ravki can be made either of hair or of wool.
What are 'Ravki'?
Answers to questions
(b) If Ravki made of hair belonging to a Nochri require Niguv, what must one
do to them if they are made of wool? Why the difference?
(c) What must one do in this case (as well as in the case that follows) if
there are knots?
(d) Rav Yehudah also discusses baskets and a bee-hive-shaped contraption for
sifting wine. If it is made of palm-branches, it requires rinsing out.
What Hechsher does it require, assuming it is made of ...
- ... sedge (a kind of rush)?
- ... flax?
(a) Rebbi and Rebbi Chiya argue over a case where an Am ha'Aretz touched a
cluster of grapes that is lying in the wine in the wine-press.
If one of
them declares all the wine in the winepress Tamei, what does the other one
(b) What does the Mishnah in Taharos rule in a case where a Sheretz is found
among the olives that are being ground in a mill, assuming the oil is ...
(c) How do we reconcile this with the one who declares the wine in the
- ... not flowing yet?
- ... already flowing?
(d) What did the Rabbanan indicate to Rebbi Yirmiyah (or to his son)?
(a) What is the Tana of our Mishnah referring to when he rules that someone
who purchases something that requires ...
(b) What examples does the Tana give for the latter case?
- ... Tevilah, has to Tovel it?
- ... Hag'alah, needs to make Hag'alah?
- ... burning in fire, must burn it in fire?
(c) What does the Tana say about a knife?
(d) What does the Beraisa add to our Mishnah? What do all the cases have in
(a) What do we learn from the Pasuk in Matos (in connection with the K'lei
Midi'an) "Kol Davar Asher Yavo ba'Eish, Ta'aviru ba'Eish (ve'Taher)"?
(b) What does Rava then learn from the word "ve'Taher"?
(c) The Torah continues "Ach be'Mei Nidah Yischata".
What does bar Kapara,
citing a Beraisa, learn from the word "Ach"?
(a) Seeing as the utensils do not require sprinkling with the ashes of the
Parah Adumah, why does the Torah then write "be'Mei Nidah"?
(b) If, as we just explained, the Torah needed to write "be'Mei Nidah", to
teach us that the utensils must be Toveled in a Kasher Mikveh, why did the
Torah then find it necessary to write "ve'Taher", as well?
(c) How does Rav Nachman Amar Rabah bar Avuhah extrapolate from "Kol Davar
Asher Yavo ba'Eish" that even new vessels that one obtains from a Nochri
also require Tevilah?
(d) In that case, Rav Sheishes asked Rav Nachman (seeing as even new
utensils require Tevilah) why do a pair of tailor's scissors that one
purchased from a Nochri does not require Tevilah too.
What did Rav Nachman
reply? What was his source for saying that?
(a) From where did Rav Nachman Amar Rabah bar Avuhah learn that utensils
that one borrows from a Nochri need not be Toveled?
(b) Does this mean that borrowed vessels may be used without being Kashered?
(a) When Rav Yitzchak bar Yosef wanted to Tovel an eating utensil made of
earth and animal dung, Rebbi Ya'akov pointed out to him what he heard from
What was that?
(b) What does Rav Ashi say about glass utensils?
(c) Rav Acha and Ravina argue over earthenware utensils that have been
overlaid with lead.
What is the basis of their Machlokes?
(d) What is the Halachah?
(a) What did Rav Ashi do with a silver utensil that he received from a
Nochri as a Mashkon?
Answers to questions
(b) What did Mar bar Rav Ashi learn from his father's actions?
(c) Why did he not conclude from there that a Mashkon is considered a sale
in this regard? Why might another Mashkon not require Tevilah?
(d) Another Beraisa gives a detailed list of the Dinim of Kashering utensils
obtained from a Nochri.
What does the Tana say there about utensils that
were used in cold water?
