Previous daf Chulin 51
CHULIN 51-54 - sponsored by Dr. Lindsay A. Rosenwald of Lawrence NY, in
honor of his father, David ben Aharon ha'Levy Rosenwald of blessed memory.
1) A NEEDLE IN THE "BEIS HA'KOSOS"
(a) (Mishnah): The Masas or the Beis ha'Kosos (these are
intermediate stomachs) was punctured...
2) CONCERN THAT LIMBS WERE CRUSHED
(b) (Beraisa): If a needle was found in the wall of the Beis
1. If the wall is punctured on one side, it is Kosher;
if it is punctured on both sides, it (the animal) is
(c) (If Reuven bought this animal, if it was already
Tereifah, it was Mekach Ta'us (a mistaken sale), he
returns the carcass and gets his money back.) If a scab
formed, the puncture was at least three days before the
2. If a drop of blood is found, it was punctured before
slaughter (it is Tereifah); if no blood is found, it
was punctured after slaughter (it is Kosher.)
1. If no scab formed, Reuven must prove that it was
Tereifah when he bought it.
(d) Question: Why is this different than other punctures,
they are Tereifah even if blood is not found!
(e) Answer: If there is nothing for the blood to stick to, it
is washed away; here (if it was before slaughter), the
blood sticks to the needle.
(f) (Rav Avira) Rebbi declared an animal Tereifah because a
needle was found with one end in the wall of the Beis
1. He had turned the Beis ha'Kosos inside out and found
a drop of blood on the needle.
2. Rebbi: The blood proves that the needle had gone all
the way through; it later moved back.
(a) (Mishnah): If it fell from the roof...
3) CONCERN THAT LIMBS WERE CRUSHED (cont.)
(b) (Rav Huna): If one left an animal on the roof, and later
he finds it on the ground, we are not concerned that
limbs were crushed.
(c) Ravina'a goat was on the roof; it looked through an
opening in the roof and saw barley on the floor (in the
house) and jumped to the floor.
(d) Question (Ravina): Why did Rav Huna say that we are not
concerned when it jumped from the roof?
1. If it is because the animal softens the fall by
dragging its forelegs on the wall - here, there was
nothing to grasp, we are concerned!
(e) Answer (Rav Ashi): The latter reason is correct.
2. If it is because the animal would not jump unless it
estimated that it can survive the fall - here also,
we are not concerned.
(f) A sheep in Rav Chaviva's house was dragging its hind
(g) (Rav Yeimar): This is due to a leg sickness, it is
(h) Question (Ravina): Perhaps it is because the spinal cord
snapped, and it is Tereifah!
(i) They checked it; indeed, the spinal cord had snapped.
(j) Nevertheless, the Halachah follows Rav Yeimar - leg
sicknesses are common, a snapped spinal cord is not (so
one need not check.)
(k) (Rav Huna): We are not concerned about rams that gore
each other (lest their limbs were crushed);
1. Even if they are in pain, this is merely a fever.
(l) (Rav Menasheh): If a thief dropped rams over the wall, we
are not concerned that their limbs were crushed.
2. If the animal fell to the ground, we are concerned.
1. This is because the thief drops them gently on their
legs so they will be able to run.
(m) If the thief dropped them over the wall again to return
them, surely we are concerned!
1. This is only if he returned them out of fear of
being caught (perhaps he did not drop them gently);
(n) (Rav Yehudah): If one hit an animal with a staff from the
head to the tail, or from tail to head, since the entire
backbone was hit, the blow was not intense in any one
place, we are not concerned for crushed limbs.
2. If he returns them to repent, we are not concerned -
surely, he wants to repent properly.
1. If the end of the staff reached to the middle of the
backbone, or if there are protrusions in the staff,
we are concerned.
(a) (Rav Nachman): We are not concerned that the limbs of a
newborn animal were crushed in delivery.
(b) Support (Rava - Beraisa): Even a baby of one day can
become a Zav (through emissions from his Ever.)
4) A BIRD THAT FELL
1. If we would be concerned that limbs are crushed in
birth, we would attribute the emission to the birth,
and he would not be considered a Zav - "(An
emission) from his flesh", not due to Ones (another
(c) Rejection: Perhaps only a baby born through Yotzei Dofen
(Caesarean section) can become a Zav (for it is not
pressured during birth.)
(d) Support (Beraisa): A calf born on Yom Tov may be
slaughtered (and eaten) that same day.
(e) Rejection: The case is, it was a Yotzei Dofen.
(f) Support (Beraisa): All agree that if a Bechor was born
blemished (on Yom Tov), it is Muchan (prepared (as
opposed to Muktzeh), it may be slaughtered that day.)
1. Suggestion: Perhaps this is no support, it was a
(g) Rejection: The case is, the animal moved to stand (but if
not, we would be concerned that its limbs were crushed.)
2. Rejection: If so, even if it was unblemished, it
would not be Kodesh!
3. (R. Yochanan): R. Shimon (who says that the Tum'like
and Korban Yoledes apply to a Yotzei Dofen birth)
agrees that a Yotzei Dofen (animal) cannot be a
(h) (Rav Nachman): If an animal was thrown to the ground to
be slaughtered, we are not concerned for crushed limbs.
(i) An ox fell and was whining from the pain; Rav Yitzchak
bar Shmuel bar Marsa bought some of the meat.
1. Rabanan: How do you know that it is permitted?
(j) (Rav Yehudah): If an animal fell:
2. Rav Yitzchak: Rav said, it digs its nails into the
ground to soften the fall.
1. If it stands up, one need not wait 24 hours before
slaughtering it, but it must be checked;
(k) (R. Chiya bar Ashi): In both cases, it must be checked.
2. If it walks, it need not be checked.
(l) (R. Yirmeyah bar Acha): If it sticks out a foreleg,
trying to stand, this is like standing;
1. If it sticks out a hind leg, trying to walk, this is
(m) (Rav Chisda): If it stirred itself to stand (even without
sticking out a limb), this is like standing.
(n) (Ameimar): If an animal fell, the intestines must be
(o) (Mar Zutra): The entire inside must be checked (i.e.
including the ribs and vertebrae.)
(p) Question (Huna Mar bar brei d'Rav Nechemyah): Must the
Kaneh and Veshet be checked (lest they were uprooted?)
(q) Answer (Rav Ashi): No, they are sturdy, we are not
(a) (Rav Yehudah): If a bird fell onto water, and it swims
its own length, it is Kosher.
1. This is only if it swims upstream - if it goes
downstream, perhaps the water carried it (we treat
it like an animal that fell.)
(b) If a bird lands on any if the following, it has the law
of a fallen animal:
2. In still water, it suffices if it swims in any
3. Swimming downstream suffices if it goes faster than
wood floating in the water.
1. A garment that was stretched out tightly; a net in
which the ropes are close together; bundles of flax
or combed flax or reeds; flax that was beaten but
not shaken; stubble that comes off flax (unless it
is very fine);
2. Moss, unless it was cut into strips; sifted ashes;
coarse sand; dirt on the road; bundled straw; wheat,
barley and related grains; clover; chickpeas.
