1)

(a)We query Rebbi Yitzchak (who learns that "Tzipor" refers to Tahor birds exclusively) from the Pasuk in Re'ei "Kol Tzipor Tehorah Tocheilu". If "Tehorah" does not come to preclude Tamei birds (which would then be included in "Tzipor"), what does it come to include?

(b)Why can forbidden in this context not mean T'reifos?

(c)On what grounds do we accept the explanation that it comes to preclude the Shechutah of a Metzora, even though we already learn it from the Seifa "ve'Zeh asher Lo Sochlu meihem"?

(d)Then why, by the same token, can we not learn T'reifah from there, and say that we need the Pasuk to teach us an extra Asei?

1)

(a)We query Rebbi Yitzchak (who learns that "Tzipor" refers to Tahor birds exclusively) from the Pasuk "Kol Tzipor Tehorah Tocheilu". "Tehorah" does not come to preclude Tamei birds (which would then be included in "Tzipor") - but birds that are forbidden.

(b)Asur in this context cannot mean T'reifos - because we already know that from the Pasuk in Emor "Neveilah u'Tereifah Lo Yochal ... ".

(c)We accept the explanation that it comes to preclude the Shechutah of a Metzora, even though we already learn it from the Seifa "ve'Zeh asher Lo Sochlu meihem" - because whereas the latter teaches us a Lo Sa'aseh, our Pasuk adds an Asei to the prohibition.

(d)We cannot however, by the same token, learn T'reifah from there, and say that we need the Pasuk to teach us an extra Asei - because the Pasuk is talking about a regular Shechutah (and Davar ha'Lameid mi'Inyano is one of the thirteen principles through which the Torah is Darshened), and not a T'reifah.

2)

(a)We query Rebbi Yitzchak from the Pasuk in Tazri'a "Sh'tei Tziparim Chayos", which we initially interpret as she'Chayos be'Ficha. What does this ...

1. ... mean?

2. ... imply?

(b)How do we refute the Kashya on Rebbi Yitzchak? How will he interpret "Chayos"?

(c)What problem do we then have with the Seifa "Tehoros"? What does that imply?

(d)How do we counter the answer that "Tehoros" comes to preclude T'reifos (and not Temei'os)?

(e)According to which opinion can we indeed learn T'reifos from "Chayos"?

2)

(a)We query Rebbi Yitzchak further from the Pasuk in Tazri'a "Sh'tei Tziparim Chayos", which we initially interpret as she'Chayos be'Ficha which ...

1. ... means a Tahor species, and which in turn, ...

2. ... implies that "Tziparim" incorporates Tamei species (a Kashya on Rebbi Yitzchak).

(b)We refute the Kashya however - by reinterpreting "Chayos" to mean that all the limbs are alive (to preclude one with missing limbs from being used for the Taharah of a Metzora).

(c)The problem with the Seifa "Tehoros" is that - we can nevertheless extrapolate from there that there are Tziporim that are Tamei.

(d)We counter the answer that "Tehoros" comes to preclude T'reifos (and not T'mei'os) - by referring to "Chayos", which already automatically precludes T'reifos (leaving the Kashya intact).

(e)And we uphold the Kashya - according to those who hold that T'reifos cannot live (but according to those who maintain that they can, "Tehoros could indeed come to preclude T'reifos and not T'mei'os).

3)

(a)In any event, we already know that the Tziprei Metzora are Pasul from Tana de'bei Rebbi Yishmael, who compares Machshir to Mechaper, ba'Chutz just like we compare them bi'Fenim. What are Machshir and Mechaper ...

1. ... ba'Chutz?

2. ... bi'Fenim?

(b)In what respect does Tana de'bei Rebbi Yishmael now learn Tziprei Metzora Sa'ir from ha'Mishtale'ach?

(c)From where do we know that the Sa'ir ha'Mishtale'ach may not be a T'reifah?

(d)Rav Nachman bar Yitzchak therefore learns from "Sh'tei Tziparim ... Tehoros" to preclude the birds of an Ir ha'Nidachas. Why can this only pertain to the Shechutah, but not to the Meshulachas?

3)

(a)In any event, we already know that the Tziprei Metzora are Pasul from Tana de'bei Rebbi Yishmael, who compares Machshir to Mechaper, ba'Chutz just like we compare them bi'Fenim. 'Machshir' and 'Mechaper ...

1. ... ba'Chutz' refer respectively - to Asham Metzora and Chatas Mechusrei Kaparah (which permit the Metzora and the Mechusrei Kaparah to eat Kodshim) and all other Chata'os and Ashamos.

2. ... bi'Fenim' are - the Tziprei Metzora which come to render him Tahor and the Sa'ir ha'Mishtale'ach, which comes to atone.

(b)And Tana de'bei Rebbi Yishmael now learns Tziprei Metzora from Sa'ir ha'Mishtale'ach - with regard to disqualifying T'reifos.

(c)We know that the Sa'ir ha'Mishtale'ach cannot be a T'reifah - because, due to the fact that the two goats are chosen by Goral (lots), only a goat that is eligible for "la'Hashem" is eligible for Az'azel.

(d)Rav Nachman bar Yitzchak therefore learns from "Sh'tei Tziparim ... Tehoros" to preclude the birds of an Ir ha'Nidachas. This can only pertain to the Shechutah, but not to the Meshulachas - because the Torah would not permit sending something that is Asur be'Hana'ah as a stumbling-block for anyone who catches it, and unaware that it is Asur, Shechts and eats it.

4)

(a)Rava learns from "Tehoros" that one is not permitted to take the remaining bird from one Metzora to use for another Metzora. Why can he only be referring to taking the bird to pair off with the Shechutah of the second Metzora (but not with the Meshulachas)?

(b)So what is the Torah then coming to teach us?

(c)According to Rav Papa, the Pasuk is coming to preclude using a bird that one purchased in exchange for Avodah-Zarah. What is the status of this bird?

(d)Why can Rav Papa only be referring to using it as the Shechutah, but not the Meshulachas?

4)

(a)Rava learns from "Tehoros" that one is not permitted to take the remaining bird from one Metzora to use for another Metzora. He can only be referring to taking the bird to pair off with the Shechutah of the second Metzora (but not with the Meshulachas) - seeing as it already requires sending away from the first time (in which case it is obvious that it cannot now be Shechted).

(b)So the Torah must be coming to teach us that - one cannot use one and the same bird as the Meshulachas of two Metzora'im.

(c)According to Rav Papa, the Pasuk is coming to preclude using a bird that one purchased in exchange for Avodah-Zarah - which (based on the Pasuk "Vehayisa Cherem Kamohu") is Asur be'Hana'ah.

(d)Rav Papa can only be talking about using it as the Shechutah, but not as the Meshulachas - because, as we just explained, we cannot send a bird that is Asur away to a place where people might catch and eat it.

5)

(a)Finally, Ravina precludes from "Tehoros" a bird that killed someone. Why can the Pasuk not be referring to one whose Din has already been concluded?

(b)If the Pasuk is then referring to one whose Din has not yet been concluded, why can it not be coming to preclude bringing it as the Meshulachas?

(c)So what do we learn from "Tehoros", according to Ravina?

(d)Why does our Mishnah exempt ...

1. ... a Tamei bird that is sitting on the eggs of a Tahor bird from Shilu'ach?

2. ... a Tahor bird that is sitting on the eggs of a Tamei one?

5)

(a)Finally, Ravina precludes from "Tehoros", a bird that killed someone. The Pasuk cannot be referring to one whose Din has already been concluded - since Beis-Din are obligated to put it to death.

(b)So the Pasuk must be referring to one whose Din has not yet been concluded, in which case it cannot be coming to preclude bringing it as the Meshulachas - since one is already obligated to bring it to Beis-Din in order to 'destroy the evil from your midst'.

(c)What we learn from "Tehoros" according to Ravina is that - one cannot perform the Mitzvah of "u'Vi'arta ha'Ra mi'Kirbecha" by Shechting it as the Shechutah on behalf of a Metzora.

(d)Our Mishnah exempts ...

1. ... a Tamei bird that is sitting on the eggs of a Tahor bird from Shilu'ach - because the mother is not a Tzipor.

2. ... a Tahor bird that is sitting on the eggs of a Tamei one - because they are only fit to feed one's dogs, but not to eat oneself (as we shall now explain).

6)

(a)What does Rav Kahana learn from the Pasuk in Ki Seitzei (in connection with Shilu'ach ha'Kein) "(ve'es ha'Banim) Tikach lach"?

(b)And he bases this on a Beraisa. What does the Tana say about a case where ...

1. ... the mother is a T'reifah?

2. ... the babies are T'reifos?

(c)We query this inasmuch as the Torah compares the mother to the babies (in which case the Tana ought to have exempted the former case too, from Shilu'ach ha'Kein. How do we answer this Kashya?

(d)How does Abaye amend the Beraisa 'Eim Efrochim T'reifah Chayav be'Shilu'ach' (seemingly clashing with the previous Beraisa)?

6)

(a)Rav Kahana learns from the Pasuk in Ki Seitzei (in connection with Shilu'ach ha'Kein) "(ve'es ha'Banim) Tikach lach" that the Chiyuv only pertains to babies or eggs that arfe edible (as we just explained).

(b)And he bases this on a Beraisa, where the Tana rules that in a case where ...

1. ... the mother is a T'reifah - the Din of Shilu'ach nevertheless applies, but where ...

2. ... the babies are T'reifos - it does not.

(c)We query inasmuch as the Torah compares the mother to the babies (in which case, the Tana ought to have exempted the former case too from Shilu'ach ha'Kein). And we answer - by citing the D'rashah "Tzipor", from which the Tana precludes Tamei (mother) birds from Shilu'ach, which would be superfluous if the mothers had to be edible.

(d)Abaye amends the Beraisa 'Eim Efrochim T'reifah Chayav be'Shilu'ach' (seemingly clashing with the previous Beraisa) to - 'Efro'ach, she'Iman T'reifah, Chayav be'Shilu'ach'.

7)

(a)What She'eilah (that remains unresolved) does Rav Hoshaya ask about a case where someone Shechts a minority of the baby birds whilst they are still in the nest. Why might he be ...

1. ... Patur from Shilu'ach?

2. ... Chayav Shilu'ach?

(b)Rebbi Yirmiyah asks what the Din will be if the mother is sitting on a cloth which divides between it and the babies. What is the basis of the She'eilah?

(c)He then goes on to ask what the Din will be if 1. loose feathers, 2. ... eggs that will not hatch, 3. a row of regular eggs, 4. a male bird interrupt between the mother and the eggs. What does each subsequent She'eilah hold regarding the previous one?

(d)What is the outcome of all these She'eilos?

7)

(a)Rav Hoshaya asks whether if someone Shechts a minority of the baby birds whilst they are still in the nest, he might be ...

1. ... Patur from Shilu'ach - because on the one hand, the bird stands to die, in which case we will apply the D'rashah "Tikach lach", 've'Lo li'Kelavecha'.

2. ... Chayav Shilu'ach - because on the other hand, it lies within his ability to complete the Shechitah.

(b)Rebbi Yirmiyah asks what the Din will be if the mother is sitting on a cloth which divides between it and the babies - because when the Torah writes "ve'ha'Eim Rovetzes al ha'Banim', maybe the mother needs to sit on the babies and not on a cloth (which is a Chatzitzah).

(c)He then goes on to ask what the Din will be if 1. loose feathers, 2. ... eggs that will not hatch, 3. a row of regular eggs, 4. a male bird interrupt between the mother and the eggs. Each subsequent She'eilah holds - that in the previous one, it is considered a Chatzitzah, because in each subsequent case, the object that is Chotzetz is more similar to the eggs that in the one before.

(d)The outcome of all these She'eilos is Teiku.

8)

(a)And Rebbi Zeira asks what the Din will be if a T'sil (a species of dove) is sitting on the eggs of a dove, or vice-versa. How does Abaye try to resolve the She'eilah from our Mishnah which exempts a Tamei bird that is sitting on the eggs of a Tahor one or vice-versa, from Shilu'ach? What does he try to extrapolate from there?

(b)How do we refute Abaye's proof? Which kind of Tahor bird might the Mishnah be coming to include (in the Din of Shilu'ach)?

(c)Rebbi Eliezer in our Mishnah includes a male Korei (partridge) sitting on another bird's eggs in the Din of Shilu'ach. How does Rebbi Avuhu learn this from the 'Gezeirah-Shavah' "Korei Dagar (meaning a bird's call) ve'Lo Yalad" (Yirmiyah) from the Pasuk in Yeshayah "u'Vak'ah ve'Dagrah be'Tzilah"?

8)

(a)And Rebbi Zeira asks what the Din will be if a T'sil (a species of dove) is sitting on the eggs of a dove, or vice-versa. Abaye tries to resolve the She'eilah from our Mishnah, which exempts a Tamei bird that is sitting on the eggs of a Tahor one, or v ice-versa, from Shilu'ach - implying that a Tahor bird on the eggs of a Tahor bird is Chayav.

(b)We refute Abaye's proof however - by restricting the implication to a female Korei (A partridge), which is different than other birds, as we shall see shortly.

(c)Rebbi Eliezer in our Mishnah includes a male Korei sitting on another bird's eggs in the Din of Shilu'ach. Rebbi Avuhu learns this from the Gezeirah-Shavah "Korei Dagar (meaning a bird's call) ve'Lo Yalad" from the Pasuk in Yeshayah "u'Vak'ah ve'Dagrah be'Tzilah" - from which we learn that a male Korei is as attached to the birds in whichever nest it is sitting as the female Korei is to its own young.

9)

(a)What does Rebbi Elazar say regarding ...

1. ... a female Korei sitting on the eggs of another bird?

2. ... another male bird sitting on the eggs even of its own species?

(b)Why does Rebbi Elazar need to make ...

1. ... the former statement? Why is it not obvious from the fact that the Rabbanan and Rebbi Eliezer argue specifically regarding a male?

2. ... the latter statement? Why is it not obvious from the fact that they argue specifically about a male Korei (and not about any other male bird)?

(c)And we support this latter answer with a Beraisa. What does the Beraisa say?

9)

(a)Rebbi Elazar states that in a case where ...

1. ... a female Korei sits on the eggs of another bird - even the Rabbanan will agree that it is subject to Shilu'ach.

2. ... another male bird sits even on the eggs of its own species that - even Rebbi Eliezer will agree that it does not require Shilu'ach.

(b)Rebbi Elazar needs to make ...

1. ... the former statement, because we might have otherwise thought that - they really argue in both cases, and the Beraisa only mentions a male - to teach us that Rebbi Eliezer argues even there.

2. ... latter statement, because we might have otherwise thought that - they really argue in both cases, and the Beraisa mentions only a male Korei - to teach us that even there, the Rabbanan exempt the male from the Din of Shilu'ach (despite the fact that it is normal for it to do so).

(c)And we support this latter answer with a Beraisa, which specifically states that - a male bird is not subject to Shilu'ach ha'Kein, and it is only by a male Korei that the Tana'im argue.

10)

(a)Under what condition does our Mishnah exempt a mother bird that is hovering over the nest, from Shilu'ach?

(b)We already learned from the word "Kan" that one is Chayav to send away the mother bird even for just one baby or one egg. What does the Tana learn from the Pasuk "ve'ha'Eim ... al ha'Efrochim O al ha'Beitzim"? Why does the Torah compare ...

1. ... the eggs to the fledglings?

2. ... the fledglings to the eggs?

(c)The Beraisa Darshens "Rovetzes" (crouching), 've'Lo Me'ofefes' (flying). From where does the Tana now learn that as long as the bird's wings are touching the nest, it is subject to Shilu'ach?

(d)What does Rav Yehudah Amar Rav say about a bird whose wings are resting on two branches of a tree (Sh'nei Rovdim)? Under which two conditions is it subject to Shilu'ach, even though it is not actually touching the nest?

10)

(a)Our Mishnah exempts a mother bird that is hovering over the nest, from Shilu'ach - provided it is not touching it.

(b)We already learned from the word "Kan" that one is Chayav to send away the mother bird even for just one baby or one egg. The Tana learns from the Pasuk "ve'ha'Eim ... al ha'Efrochim O al ha'Beitzim" where the Torah compares ...

1. ... the eggs to the fledglings - to exempt eggs that will not hatch.

2. ... the fledglings to the eggs - to exempt fledglings that can already fly and no longer need their mother.

(c)The Beraisa Darshens "Rovetzes" (crouching), 've'Lo Me'ofefes' (flying). And the Tana then learns that as long as the bird's wings are touching the nest, it is subject to Shilu'ach - because otherwise, the Torah ought to have written 'Yosheves'.

(d)Rav Yehudah Amar Rav rules that a bird whose wings are resting on two branches of a tree (Sh'nei Rovdim) is subject to Shilu'ach (even though it is not actually touching the nest) - provided 1. if one were to move the branches aside, the bird would fall, and 2. the eggs are directly beneath it (so that it would actually fall on top of them).

11)

(a)We query Rav Yehudah Amar Rav from a Beraisa which exempts a mother bird who is sitting in between the eggs from Shilu'ach. What does the Tana say about a case where it is ...

1. ... sitting above them?

2. ... hovering over them (even if it is touching them)?

(b)How do we query Rav Yehudah, based on the assumption that Mah Beineihen de'Nag'ah b'hu, Af al-Gabeihen de'Nag'ah b'hu?

(c)Why do we not then ask directly from our Mishnah, which requires the mother to be touching the nest, in order to require Shilu'ach?

11)

(a)We query Rav Yehudah Amar Rav from a Beraisa, which exempts a mother bird who is sitting in between the eggs from Shilu'ach. The Tana rules that if the mother bird is ...

1. ... sitting above them - it is subject to Shilu'ach.

2. ... hovering over them (even if it is touching them) - it is Patur.

(b)Based on the assumption that Mah Beineihen de'Nag'ah b'hu, Af al-Gabeihen de'Nag'ah b'hu, we query Rav Yehudah - who does not require the mother must touch the nest in order to be subject to Shilu'ach.

(c)We cannot however, ask directly from our Mishnah, which requires the mother to be touching the nest - because the Mishnah is speaking about where the mother is hovering, in which case even Rav Yehudah agrees that it must touch the nest.

12)

(a)How do we refute the Kashya on Rav Yehudah Amar Rav? If the Tana does not intend to compare 'al-Gabeihen to Beineihen in this way, then why does he mention them together?

(b)And how do we try to prove this from the Seifa, where the mother was hovering over the nest? What ought the Tana to have said, if resting on the branches would be Patur?

(c)We refute this proof however, on the grounds that, from another point of view, the case of hovering is a bigger Chidush. Why is that?

(d)How do we reconcile the Seifa of the Beraisa with our Mishnah, which requires Shilu'ach, if the mother is touching the nest?

12)

(a)We answer by changing the comparison of al-Gabeihen to Beineihen inasmuch as - just as the latter case, the mother is not touching the top of the eggs, so too, does the former not need to (which conforms with Rav Yehudah Amar Rav's ruling).

(b)We try to prove this from the Seifa, where the mother was hovering over the nest. Now if the mother resting on the branches would be Patur - then the Tana ought to have mentioned that case, where the mother does not require Shilu'ach even though it is actually resting in the nest (which the hovering mother is not).

(c)We refute this proof however, on the grounds that, from another point of view, the case of hovering is a bigger Chidush - since it is Patur from Shilu'ach, even though it is actually touching the nest (which the resting bird is not).

(d)To reconcile the Seifa of the Beraisa with our Mishnah, which requires Shilu'ach, if the mother is only touching the nest - Rebbi Yirmiyah establishes the Beraisa where it is touching the eggs from the side and not on top (whereas the Torah writes "ve'ha'Eim Rovetzes al ha'Banim").

13)

(a)In the second Lashon, we try to support Rav Yehudah from the Beraisa by suggesting that Mah Beineihen de'Lo Nag'ah alaihu, Af al-Gabeihen de'Lo Nag'ah alaihu (just like Rav Yehudah). How do we refute this proof?

(b)In that case, why does the Seifa present the case of where the bird is hovering over the nest? Why does the Tana not rather present the case of Rovdei Ilan, where it does not require Shilu'ach, even though it is resting inside it?

(c)And how does Rav Yehudah reconcile the Seifa of the Beraisa with our Mishnah, which requires Shilu'ach once the mother bird is touching the nest?

13)

(a)In the second Lashon, we try to support Rav Yehudah from the Beraisa by suggesting that Mah Beineihen de'Lo Nag'ah alaihu, Af al-Gabeihen de'Lo Nag'ah alaihu (just like Rav Yehudah). We refute this proof however - by switching the comparison to Mah Beineihen de'Nag'ah b'hu, Af al-Gabeihen de'Nag'ah b'hu (which becomes a Kashya on Rav Yehudah, like we saw in the first Lashon).

(b)Nevertheless, the Seifa presents the case of where the bird is hovering over the nest (rather than that of Rovdei Ilan, where it does not require Shilu'ach, even though it is resting) - because it is a bigger Chidush, in that it does not need Shilu'ach even though it is actually touching the nest (which in the cased of Rovdei Ilan, it is not).

(c)And Rav Yehudah reconciles the Seifa of the Beraisa with our Mishnah, which requires Shilu'ach once the mother bird is touching the nest - by establishing it where it is touching the eggs from the side and not on top (as Rebbi Yirmiyah explained in the first Lashon).
