CHULIN 47-50 - sponsored by Dr. Lindsay A. Rosenwald of Lawrence NY, in
honor of his father, David ben Aharon ha'Levy Rosenwald of blessed memory.
1) PROBLEMS IN THE LUNGS
(a) (Rava): If two adjacent scabs are found, it does not help
1. If one scab appears like two, we puncture one side
of it. If the pus moves from one side to the other,
this shows that it is a single scab, it is Kosher;
(b) (Rava): There are five chambers in the lungs - three on
the right, two on the left.
2. If not, it is two scabs, it is Tereifah.
1. If there are fewer or more than this, or if they are
out of place, it is Tereifah.
(c) An animal with an extra chamber was brought before
Mereimar; he ruled that it is Kosher.
1. Rav Acha told the owner to ask Mereimar to look
(d) An animal with an extra chamber (not in line with the
others) was brought before Rav Ashi; he was about to rule
that it is Tereifah.
2. Mareimar: The Halachah is not like Rava regarding an
i. This is only if the extra chamber is in line
with the others; if not, it is Tereifah.
1. Rav Huna bar Mar Avya: All healthy (alternatively -
self-grazing) animals have this; butchers call it
the rose (colored) mini-chamber.
i. This is only if the extra chamber is inside the
others - if it is outside, even if it is no
bigger than a myrtle leaf it is Tereifah.
2) THE APPEARANCE OF THE LUNGS
(a) (Rafram): If the lungs resemble spliced wood, it is
3) HOLES IN THE LUNGS
1. Version #1: This means, their color is like wood.
(b) (Rava): If the lungs are blue, it is Kosher; if they are
black, it is Tereifah.
2. Version #2: This means, they feel like wood.
3. Version #3: This means, they are white like wood
4. Version #4: This means, they are hard like wood.
5. Version #5: This means, they are smooth like wood,
the chambers are not delineated.
1. (R. Chanina): Black was originally red, it was
(c) From R. Noson we learn that red and green are Kosher.
1. (Beraisa - R. Noson): I met two women, each had lost
two sons through circumcision. The third baby of one
of them was red, the other's third baby was green. I
counseled them to postpone the circumcision until
the blood was absorbed; both babies survived the
(d) (Rav Kahana): If the lungs are like (the color of) a
liver, it is Kosher; if they are like flesh, it is
(e) (Rav Sama brei d'Rava): If the Lungs are like hops,
saffron or an egg, it is Tereifah.
(f) Question: If so, what is the case of green that is
(g) Answer: If they are green like leeks, it is Kosher.
(h) (Ravina): If part of the lungs is stopped up, one cuts
1. If pus comes out - surely, this was clogging them,
the animal is Kosher;
2. If not, one puts a feather or spit on the clogged
area. If it moves when one blows through the lungs,
it is Kosher; if not, it is Tereifah.
(a) (Rav Yosef): A scab over a wound in the lungs is of no
significance (since it will break), the animal is
(b) (Rav Yosef): If when one blows into the lungs, it sounds
like air is escaping, he must check it.
1. If he knows where the sound comes from - he puts a
feather, piece if straw or some spit there. If there
really is a hole, they will move when he blows.
(c) (Ula): If the inside of the lungs pours like water, it is
2. If he does not know where the sound comes from - he
puts the lungs in a basin of lukewarm water and
blows into the lungs.
i. Hot water may not be used - this would
constrict the hole.
3. If this makes bubbles, there is a hole, it is
ii. Cold water should not be used - this could tear
the outer membrane.
i. If there are no bubbles, the noise was due to a
tear in the lower membrane alone, it is Kosher.
1. He must hold that an internal Chisaron (something
missing) in the lungs (that allows the contents to
flow from one side to the other) does not make it
(d) Question (R. Aba - Mishnah): If the lungs were punctured
or Chaserim (it is Tereifah).
1. Question: What is the case of Chaserim?
(e) Answer: Really, the Chisaron extends to the outside; R.
Shimon taught this clause, he says that a punctured lung
is Tereifah only if the hole extends to the main branch.
i. Suggestion: If they are Chaserim on the
outside, they are punctured!
2. Answer: Rather, there is an internal Chisaron.
1. This is only if flesh of the lung is not missing; if
flesh is missing, he agrees that it need not extend
to the main branch.
(f) R. Chananyah ruled that if the inside of the lungs pours
like water, it is Kosher.
1. (Rava): This is only if the branches are intact.
(g) (Rav Nachman): If some of the interior of the lungs is
missing but the membrane is intact, it is Kosher.
2. Question: (Rav Acha brei d'Rava): How can one know
that all the branches are intact?
3. Answer (Rav Ashi): One pours out the insides onto a
lead-glazed bowl. If one sees white dots, branches
were dissolved; if not, all are intact.
1. Support (Beraisa): If some of the interior of the
lungs is missing but the membrane is intact, even if
a Revi'is is missing, it is Kosher;
2. If the womb was removed, it is Kosher;
3. The Sanhedrin in Yavneh ruled that if the liver is
wormy, it is Kosher.
