1) IS "LIBUN" REQUIRED FOR "KODSHIM?"
(a) Contradiction (Rav Amram - our Mishnah): A roasting spit
or grill (of a Nochri) is Kashered through Libun;
2) METHODS OF "KASHERING"
1. (Mishnah): A roasting spit or grill (on which
Kodshim were cooked) is Kashered through Hag'alah in
(b) Answer #1 (Rav Sheshes): Kodshim vessels are more lenient
because they absorbed permitted taste; Nochri vessels
absorbed forbidden taste.
(c) Objection (Rabah): What difference does it make? In both
cases, they emit forbidden taste (Kodshim becomes Nosar
within a day or two)!
(d) Answer #2 (Rabah): When the Mishnah says that Hag'alah is
required for Kodshim vessels, this means Shetifah
u'Merikah (rinsing and scouring).
(e) Objection (Abaye): Shetifah u'Merikah is with cold water,
the Mishnah specifies Hag'alah, which is in hot water!
(f) Answer #3 (Abaye): Each Mishnah teaches about the other:
1. Our Mishnah teaches that Nochri vessels require
Libun - the same applies to Kodshim vessels;
(g) Objection (Rava): If so, one of the Mishnayos should have
taught Libun and Hag'alah, and the other should teach one
of these methods, and we would learn the other method
from the other Mishnah!
2. That Mishnah teaches that Kodshim vessels require
Hag'alah - the same applies to Nochri vessels.
(h) Answer #4 (Rava): Kodshim vessels do not require Libun
because of Rav Nachman's reasoning.
1. (Rav Nachman): Cooking Kodshim in a pot purges the
pot from absorptions of the previous day's Kodshim
(before they become forbidden).
(i) Objection: If so, Kodshim vessels should not even need
2. Question: This only applies to Shelamim (which may
be eaten for two days) since yesterday's absorptions
are still permitted;
i. But if Chatas was cooked yesterday, it is
forbidden today (and it forbids today's
3. After cooking Chatas, one must cook Shelamim that
same day (to purge the pot from absorbed Chatas),
the absorbed Shelamim will be purged tomorrow.
1. This is left difficult.
(j) Answer #5 (Rav Papa): Nochrim do not constantly cook in
their vessels, the absorptions become hard, Libun is
required; Kodshim vessels are used constantly, the
absorptions never become hard, Hag'alah suffices.
(k) Defense of answer #1 (Rav Ashi): Kodshim vessels are more
lenient because they absorbed permitted taste;
1. Objection (Rabah): In both cases, they emit
2. Answer (Rav Ashi): Genuine Isur never touched
Kodshim vessels, just the absorptions became Nosar.
(a) Question: What level of Libun is required?
(b) Answer (Rav Mani): One must heat them until the surface
(c) Question: How is Hag'alah of vessels done?
(d) Answer (Rav Huna): A small pot is put in a bigger pot (of
(e) Question: How is Hag'alah done for a big pot?
(f) Answer: Rav Ukva had a big pot to Kasher; he put dough
around the brim, filled it with water up to the brim, and
boiled the water.
(g) Rava: Rav Ukva is a great Chacham, he knows that this
On to Horayos
1. When Isur was cooked in the pot, sometimes (boiling)
drops would splash on top of the brim - we purge the
absorptions (Kasher it) the same way they were
absorbed, it suffices that such drops splash on the
(h) (Mishnah): A knife is Kashered by rubbing it on a
(i) (Rav Ukva bar Chama): Also, he must (Rashi; Ramban -
alternatively, he may) insert it 10 times in the ground
(j) (Rav Huna brei d'Rav Yehoshua): He must insert it in
(k) (Rav Kahana): This refers to a knife without crevices.
(l) Support (Beraisa): A knife without crevices may be
Kashered by inserting it 10 times in the ground.
(m) (Rav Huna brei d'Rav Yehoshua): This suffices to use for
1. Mar Yehudah and Bati bar Tuvi were eating with
Shevor Malka (a Nochri); Shevor Malka cut an Esrog
and gave some to Bati bar Tuvi; he inserted the
knife 10 times in the ground, cut a piece and gave
it to Mar Yehudah.
2. Bati bar Tuvi: You Kashered it for him because he is
a Yisrael - you do not consider me to be a Yisrael?!
3. Version #1 - Shevor Malka: I know that he would not
eat unless I did so - I did not know that you are so
4. Version #2 - Shevor Malka: Remember what you did
last night! (Rashi - Persian women were offered to
Bati and Yehudah, Bati accepted, Yehudah refused.
Tosfos - slaves were offered to them, Bati accepted
because he was a slave.)
