Kollel Iyun Hadaf is indebted to him for his encouragement and support and
prays that Hashem will repay him in kind.
(a) Our Mishnah lists Yayin Nesech, Avodas-Kochavim and Oros Levuvin - among
the things that are Asur and that forbid with a 'Kol she'Hu'.
(b) 'Oros Levuvin' are - skins of animals that were worshipped, and in which
a round hole is bored next to the heart, so as to cut out the animal's
heart, whilst it is still alive.
(c) The Tana also lists Shor ha'Niskal, Eglah Arufah, Tziporei Metzora and
Se'ar Nazir. We know that the hair of a Nazir is Asur be'Hana'ah - from the
Pasuk in Naso, which requires it to be placed under the pot containing the
Nazir's boiling Shelamim.
(d) And his list ends with Peter Chamor, Basar be'Chalav and Chulin
she'Nishchatu ba'Azarah - of which the Peter Chamor is redeemable by a lamb.
(a) When the Tana lists Basar be'Chalav, he is referring to - a piece of
meat that has been cooked in milk that then falls into a pot containing
(b) If a drop of milk falls into a pot of meat, or vice-versa - it becomes
Batel be'Nosen Ta'am (one in more than sixty).
(c) If the items in our Mishnah are not Batel because they are ...
1. ... 'Davar she'be'Minyan', we ask, why did the Tana not include - a piece
of Neveilah in the list.
(d) Rebbi Chiya bar Aba (or Rebbi Yitzchak Nafcha) therefore explain the
Tana's omission of a piece of Neveilah and Chametz on Pesach from the list -
because he is listing things that fall under both categories 'Isurei Hana'ah
and 'Davar she'be'Minyan'.
2. ... Isurei Hana'ah, then he ought to have included - Chametz on Pesach.
(a) The hair of a Nazir is a 'Davar she'be'Minyan' - because they tended to
tie hair into bundles and sell so many bundles per Sela in sacks.
(b) If a small piece of Chametz gets mixed up with pieces of Matzah, or a
piece of Neveilah with pieces of Kasher meat - one piece is thrown into the
river, and the rest may be fed to one's dogs.
(c) The Tana omits ...
1. ... nuts from Perech and pomegranates from Badan of Orlah and K'lai
ha'Kerem - because he has already listed them in the Mishnah in Orlah.
(d) When the Tana concludes 'Harei Eilu Asurin ve'Isuran be'Chol she'Hu', he
comes to preclude - Isurei Hana'ah that are not 'Davar she'be'Minyan', and
2. ... privately-baked loaves of bread that got mixed up with Matzah (seeing
as strictly speaking, Matzah may be anything up to a Tefach thick) - because
the Tana who considers privately-baked loaves a 'Davar she'be'Minyan' is
Rebbi Akiva, and he inserts them there, too.
(a) The Tana Kama of our Mishnah forbids all the wine in a wine-pit into
which Yayin Nesech fell. Raban Shimon ben Gamliel - permits selling the wine
to a Nochri, provided one deducts the value of the Yayin Nesech from the
(b) Shmuel rules like Raban Shimon ben Gamliel in all cases. Rav agrees - in
a case where it is barrels that got mixed up, but not wine (which actually
mixes and) where he rules like the Chachamim.
(c) Most Amora'im (Rabah bar bar Chanah Amar Rebbi Yochanan ... Rav Nachman
Amar Rabah bar Avuhah) agree - with Shmuel.
(d) The last word however, goes to Rav Nachman, who rules like Rav regarding
Yayin Nesech - and like Shmuel, regarding S'tam Yeinam.
(a) Our Mishnah rules that the stone tub (of a wine-press) which a Nochri
tarred - requires Niguv (cleaning out with ashes and water).
(b) This is necessary - because after the tarring, one tends to add a little
wine, in order to put a stop to the smoke that rises from the tar?
(c) If it is a wooden tub, Rebbi requires the same method of Hechsher as a
stone one. According to the Chachamim - one needs to peel off a layer from
the tar (known as 'Kiluf'), seeing as wood absorbs more than stone.
(d) With regard to a tub that is made of earthenware - even that will not
help (though this ruling is not unanimous, as we shall see in the Sugya).
(a) The Tana speaks specifically about a Nochri who tars a tub, says Rava.
In a case where he treads the grapes in an untarred tub - not even Niguv is
(b) Rava needs to tell us this - because otherwise, we would have ignored
the obvious implication, and explained that the Tana mentions 'she'Zafsah'
because it is more common for a Nochri to tar a wine-press than to tread the
(c) In the second Lashon, Rava rules - that a tarred tub in which a Nochri
treads grapes requires - Kiluf.
(d) Here again, we ask why this is not obvious from the Mishnah itself - and
we give the same answer as we gave before (that if not for Rava, we would
have thought that the Tana mentions 'she'Zafsah' only because it is more
common, as we explained).
(e) A tarred wine-press is more stringent in this regard - due to the cracks
in the tar that sometimes occur, that fill with wine.
(a) And we support the second Lashon with a case that took place with Rav.
Rebbi Chiya sent Rav with a certain man, who had requested that Rebbi Chiya
send someone to check the Kashrus of his wine-press.
(b) Rav's first impression was - that the tar was particularly smooth, and
that the tub only required Niguv.
(c) He changed his mind however - when he spotted cracks in the tar, in
which wine had collected, and ruled that it needed Kiluf.
(d) Rebbi Chiya actually anticipated this - by warning Rav to take care not
to arouse the ire of his colleagues in the Beis Hamedrash (by doing what he
(e) When Rav spoke of 'Chavivi', he was referring to - Rebbi Chiya, his
(a) The Beraisa discusses an earthenware tub and the jar and the funnel
(from the wine-press) that have been tarred by a Nochri. Rebbi permits them
with Niguv alone. The Chachamim require Kiluf.
(b) We know that the Tana so far is speaking a. about earthenware vessels,
and b. about an untarred tub - because he is about to move on to wood and
stone vessels on the one hand, and tarred vessels, on the other.
(c) Rebbi concedes to the Chachamim that (even untarred) jars require Kiluf
(even though a wine-press does not) - because they contain the wine for
longer periods of time.
(a) We reconcile our Mishnah, which permits Niguv in the case of a stone tub
that a Nochri tarred, and according to Rebbi, even a wooden one, with the
Beraisa, which requires a tarred tub to be peeled, even if it is made of
stone - by establishing the case when the Nochri trod the grapes (whilst our
Mishnah speaks when he did not).
(b) The problem with the Beraisa, where Rebbi permits an earthenware tub,
jar and funnel with mere Niguv is - that the Seifa of our Mishnah forbids an
earthenware tub (even with Kiluf, let alone Niguv).
(c) To resolve the discrepancy, Rava establishes our Mishnah - like the
(d) Rebbi now holds that ...
1. ... a tarred tub made of stone or of wood - requires - Niguv.
2. ... a tarred tub made of earthenware - requires - Kiluf.
3. ... an untarred tub made of earthenware requires - Niguv.
(a) 'Na'avah' is a wine-press, and when we say 'Rava Na'avah Artecho', we
mean - that Rava would Kasher thr tub of his wine-press with boiling water
(b) Rava used to send empty barrels (which had absorbed wine)to Horpanya,
with a Nochri - by placing them upside-down inside a sack, which he then
(c) ... because he maintained - that anything that is handed to a Nochri,
even for a short time period, requires a 'seal within a seal' (a decree in
case one gives it to him for a long period).
(a) According to Rav, they performed Niguv using water, whereas according to
Rabah bar bar Chanah - they used ashes.
(b) We object however, on the grounds that, on the one hand, water is not
called 'Niguv', and on the other, after cleaning the tub with ashes, one
would inevitably rinse it out with water (as we shall soon see).
(c) Consequently, Rav must mean - first with water, and then with ashes; and
Rabah bar bar Chanah - first with ashes and then with water.
(d) And we conclude that in fact, they do not argue, because they are
referring to different cases, 'Ha bi'Retivta, ve'ha be'Yabeshta' - meaning
that Rabah bar bar Chanah speaks when the tub is still wet, in which case
one first needs to dry them with ashes; whereas Rav speaks when it is
already dry, and one first needs to wet it before drying it out with ashes.
