Previous daf Bechoros 7
BECHOROS 7-10 - Ari Kornfeld has generously sponsored the Dafyomi
publications for these Dafim for the benefit of Klal Yisrael.
1) A "TAMEI" BORN TO A "TAHOR"
(a) Answer #1 (Beraisa): If a Tahor animal gave birth to a
Tamei animal, it is forbidden; if its head and majority
resemble its mother, Bechorah applies to it.
2) BODILY SECRETIONS
1. This is like R. Shimon, he does not permit eating it
unless the head and majority resemble its mother!
(b) Rejection: No, he requires similarity of the head and
majority only for Kedushas Bechor.
(c) Support: He mentioned the prohibition to eat, he did not
mention what permits it to be eaten, only what is
1. This shows that similarity of the head and majority
are not needed for eating, only for Kedushas Bechor!
(d) Rejection: No, he requires them even for eating;
1. He had to teach them regarding Bechor - one might
have thought that since it says "Ach Bechor Shor,"
it must totally resemble its mother, similarity of
the head and majority would not suffice - the
Beraisa teaches that this is not so.
(e) Version #1 - Answer #2 (Beraisa - R. Yehoshua): "Ach Es
Zeh Lo Sochelu mi'Ma'alei ha'Gera umi'Mafrisei ha'Parsah
Es ha'Gamal" - a [full] camel is forbidden, but a child
with even one Siman (i.e. resemblance to its mother) is
1. A Tamei child with one Siman born to two Tahor
parents is permitted.
(f) Rejection: The Tana holds like R. Shimon in one way (he
forbids a Tamei born to a Tahor), and argues with him in
one way (the Tana says that any resemblance to the mother
permits, R. Shimon requires the head and majority).
2. Suggestion: Perhaps one Siman suffices even if the
father is Tamei!
3. Rejection: "Seh Kevasim v'Seh Izim" - both parents
must be sheep (or goats).
4. R. Eliezer says, we do not need the verse to permit
if both parents are sheep, rather, if only the
mother is a sheep.
5. Suggestion: Perhaps it permits only if both parents
6. Rejection: "Seh... Seh" - even if only the mother is
7. Summation of answer: The Tana calls a child of Tahor
parents 'Tamei' (because it resembles a Tamei
species) - this is like R. Shimon (Chachamim permit
it, they would not call it Tamei), and one Siman
(g) Version #2 - Answer #2: We learn from the resolution of a
difficulty concerning the above Beraisa:
1. Question: R. Eliezer discusses a child of a Tahor
and Tamei - but R. Yehoshua ben Levi taught that the
following combinations cannot lead to pregnancy!
(h) Rejection: The Tana holds like R. Shimon in one way, and
argues with him in one way. (End of Version #2)
i. The male *or* female is Tahor, and the other is
2. Answer (R. Yirmeyah): In the Beraisa, the "Tamei"
father (that impregnated a Tahor animal) was itself
born to a Tahor animal; this is like R. Shimon (who
forbids eating it, therefore it is called Tamei);
ii. One is large (a work animal), and the other is
iii. [According to Chachamim, if] one is a Behemah,
the other is a Chayah;
iv. R. Eliezer and R. Yehoshua argue with this,
they say that a Chayah can impregnate a
3. The Beraisa says that one Siman is enough!
(i) Question: In the Beraisa, R. Eliezer permits Zeh v'Zeh
Gorem (something that results from two (or more) causes,
and one of the causes is forbidden), and R. Yehoshua
forbids it - elsewhere, each says the opposite!
1. (Mishnah - R. Eliezer): The offspring of a Tereifah
is invalid for a Korban;
(j) Answer - part 1: Normally, R. Eliezer forbids Zeh v'Zeh
Gorem - here is different, for the Torah could have said
2. R. Yehoshua says, it is valid.
1. It says "*Seh* Kevasim *Seh* Izim" to include any
Seh (i.e. even if its father was Tamei).
(k) Answer - part 2: Normally, R. Yehoshua permits Zeh v'Zeh
Gorem - here is different, for the Torah could have said
"Seh Keves Seh Ez";
1. It says "Kevas*im*... Iz*im*" to require that both
parents to be sheep (or goats).
(l) Answer #3 (Beraisa - R. Shimon): "Gamal" is written
twice, to forbid a camel born to a camel, and a camel
born to a cow;
1. If its head and majority resemble its mother, it may
(a) (Mishnah): What comes from something Tamei is Tamei, what
comes from something Tahor is Tahor.
(b) Question: It is permitted to drink a donkey's urine?
1. Question: Why was the question only about a donkey's
urine, not that of horses and camels?
(c) Answer (Rav Sheshes - Mishnah): What comes Min (from)
ha'Tamei is Tamei, what comes from something Tahor is
2. Version #1: We do not ask about urine of horses and
camels, for it is watery, it is not at all like milk
[of a Tamei animal, which is forbidden];
essentially, it is like the water the animal drank,
surely it is permitted.
3. We ask about donkey's urine, for it is thick, like
i. Since it is drawn from its body, it is
ii. Or, perhaps it is essentially the water the
animal drank, just the animal's body heat
1. It does not say "mi'Tamei," which connotes a part of
the Tamei animal itself (Rashi; R Gershom - anything
inside it); rather, "Min ha'Tamei," anything like
part of it (and its urine is thick like milk).
3) FISH INSIDE FISH
2. Version #2: We do not ask about urine of horses and
camels, for no one drinks this;
(d) Answer (Rav Sheshes - Mishnah): What comes from something
Tamei is Tamei, what comes from something Tahor is Tahor;
3. We ask about donkey's urine, for people drink it, it
is a cure for Yerakon (jaundice).
1. This urine comes from something Tamei. (End of
(e) Question (Beraisa): It is permitted to eat bee's honey
because bees merely spit out what they ate (from
flowers), honey does not contain any part of the bee.
(f) Answer: Rav Sheshes holds like R. Yakov:
1. (Beraisa - R. Yakov):"Ach Es Zeh Tochlu mi'Kol
Sheretz ha'Of" - but not a Tamei Sheretz ha'Of.
(g) Question: Who is the Tana of the following Mishnah?
2. Question: The previous verse explicitly forbids
3. Answer: Rather, we infer (from the inference;
alternatively - from the previous verse), you may
not eat a Tamei Sheretz ha'Of, but you may eat what
it is Mashritz (emits from its body), i.e. bee's
4. Suggestion: Perhaps even honey of Gazin (Rashi -
locust; Tosfos - falcon) and Tzir'in (hornets) are
5. Rejection: No, they are forbidden.
6. Question: [The verse does not specify which honey to
permit, so] why do we permit bee's honey and forbid
the others, and not vice-versa?
7. Answer: We permit bee's honey, for people call it
"honey," but the others are always called by an
1. (Mishnah): Honey of Gazin and Tzir'in is Tahor (not
Mekabel Tum'ah), it is permitted to eat it.
(h) Answer: It is unlike R. Yakov.
(i) Inference: The Mishnah says that it is Tahor - this means
that it is not Mekabel Tum'ah until one intends to eat
(j) Support (Beraisa): Honey (i.e. of bees, only they live)
in a hive is Mekabel Tum'as Ochlim without intent.
(k) (Rabanan): Chali (pieces of flesh that fall out of the
womb) of a Yachmur (antelope) are testicles (Rashi; R.
Gershom - eggs), they are forbidden (they are Ever Min
ha'Chai; R. Gershom - the Heter to eat bird eggs does not
apply to them).
(l) (Rav Safra): No, they come from semen of an Ayal
(gazelle). (It has difficulty mating with ewes, it tries
mating with an antelope, some of the semen falls out and
hardens; since it was originally putrid, it is
(m) (Rav Huna): Skin opposite the face of a donkey is
permitted. (Rashi - its fetal sac; presumably, the Rambam
explains this literally, for he permits this and forbids
a fetal sac.)
(n) Question: What is the reason?
(o) Answer: It is mere waste (not proper meat).
(p) Support #1 (Rav Chisda - Beraisa #1): Skin opposite the
face of a person, whether alive or dead, is Tahor.
1. Suggestion: This means, whether he is alive and his
mother died, or if he and his mother died. (This
shows that it is not proper flesh!)
(q) Rejection: No, it means whether he is alive and his
mother died (Rashi - is alive), or if he died and his
mother is alive.
(r) Support #2 (Rav Chisda - Beraisa #2): (It is Tahor)
whether the fetus and mother are both alive, or both are
(s) This support cannot be refuted.
(a) (Mishnah): If a Tamei fish swallowed a Tahor fish, it is
permitted to eat it (the swallowed fish);
(b) If a Tahor fish swallowed a Tamei fish, it is forbidden
to eat it, for it did not grow from it.
(c) (Gemara) Question: The Reisha permits only if we saw it
swallow the Tahor fish, if not we are concerned that it
grew inside the Tamei fish - what is the source of this?
(d) Answer (Beraisa): Tamei fish grow inside their mother,
Tahor fish lay eggs.
(e) Question: If Tamei fish grow inside their mother, we
should be concerned that the fish we found inside was not
swallowed (the swallowed one was digested), rather, it
(f) Answer #1 (Rav Sheshes): The case is, the interior fish
was found at the end of the digestive tract.
(g) Answer #2 (Rav Papa): The interior fish was found at the
beginning of the digestive tract.
(h) Answer #3 (Rav Nachman): The interior fish was fully
developed and grown (had it grown inside, it would not
remain until full growth).
(i) Answer #4 (Rav Ashi): Most fish that grow inside are the
same species as the mother - therefore, the Mishnah
assumes that any interior fish of a different species was
(j) (Beraisa): Tamei fish grow inside their mother, Tahor
fish lay eggs;
(k) A mother (of any species) that gives birth nurses her
young, a mother that lays eggs gathers food for her young
(alternatively, she gathers the eggs and sits on them -
1. The only exception is the bat, even though it lays
eggs, it nurses.
