(a)Rebbi Eliezer in a Beraisa, tries to prove his opinion (that Olas ha'Of le'Shem Chatas ha'Of is subject to Me'ilah) from an Asham that one Shechted in the North as a Shelamim. He must be speaking about prior to the Zerikah - because after the Zerikah, the Basar is no longer subject to Me'ilah (seeing as it is fit to be eaten by Kohanim).

(b)He proves from there that - if one changes from something that is subject to Me'ilah to something that is not (when it is Kasher), Me'ilah nevertheless applies (in which case Me'ilah should also apply in the case of Olas ha'Of that is brought as a Chatas ha'Of).

(c)Rebbi Yehoshua refutes Rebbi Eliezer's proof from there on the grounds that - whereas in the case of the Olas ha'Of, the Kohen also changed the location, in the case of the Asham, he did not.

(d)So Rebbi Eliezer tries to disprove Rebbi Yehoshua's opinion from an Asham that one Shechted in the south as a Shelamim, where besides changing its name, he also changed its location. Rebbi Yehoshua counters that - unlike the case of Olas ha'Of, where cutting only one Si'man has also changed to the Avodah of the Chatas, there is no change of Avodah in the case of the Asham (since the Avodah of the Asham and the Shelamim are the same).

2)

(a)Rebbi Eliezer remained silent. Rava asked why he did not query Rebbi Yehoshua further from Asham she'Shachto be'Darom le'Shem Shelamim be'Shinuy Ba'alim, where the Chiyuv Me'ilah remains. What Rava meant is that (before grasping Rebbi Yehoshua's real reason) - we would place Shinuy Ba'alim on a par with Shinuy Ma'asim (changing the Avodah), and just as Me'ilah applies there, so too, should it apply in the case of Chatas ha'Of.

(b)To answer the Kashya, he cited Rav Ada bar Ahavah, who gave Rebbi Yehoshua's reason as - the fact that the Olas ha'Of actually becomes a Chatas ha'Of (even to the point of being Kasher, or so we currently think) ...

(c)... thereby answering the Kashya, because - since Rebbi Eliezer did not ask it, it is clear that he realized it himself.

3)

(a)When we then ask I Hachi, Chatas ha'Of Nami, she'As'ah Lema'alah ke'Ma'aseh ha'Olah ... be'Idach Si'man, Timashech Ve'tehavi Olas ha'Of, we mean that - based on our current understanding of Rav Ada bar Ahavah (that the bird actually becomes a Kasher Chatas ha'Of, according to Rebbi Yehoshua), why does our Mishnah rule Pasul in the above case? Why do we not say that when the cuts the second Si'man, it becomes a Kasher Olas ha'Of?

(b)We try to support this Kashya by citing Rebbi Yochanan in the name of Rebbi Ban'ah, who said 'Kach hi Hatza'ah shel Mishnah' - by which we think he means that Olas ha'Of she'As'ah Lematah, is the only case in the Mishnah over which Rebbi Eliezer and Rebbi Yehoshua argue.

(c)We answer however that - Kach hi Hatza'ah shel Mishnah might mean that - their argument extends to the rest of the Mishnah too (in which case it will prove the opposite).

(d)Rav Ashi refutes the Kashya once and for all - by differentiating between an Olas ha'Of that is brought below the Chut ha'Sikra - which becomes a Chatas the moment he cuts one Si'man, with a Chatas ha'Of that is brought above it, which (bearing in mind that Melikah is Kasher anywhere on the Mizbe'ach) remains a Chatas when he cuts one Si'man, and a Pasul Chatas the moment he cuts the second one.

4)

(a)We query Rav Ada bar Ahavah from a Mishnah in Kinin, which discusses a case where Rachel and Le'ah who have given birth, purchase a pair of birds between them - where one of the women has already brought her Olah, and the other, her Chatas. And the pair of birds that they purchase is needed to make up for the two missing Korbanos.

(b)The Tana rules that, in a case where the Kohen brought ...

1. ... both birds above the Chut ha'Sikra - the Olah is Kasher, and the Chatas, Pasul.

2. ... one above the Chut ha'Sikra and one below it - both birds are Pasul ...

(c)... because for all we know, the Kohen inadvertently brought the Olah below the Chut and the Chatas above it.

(d)We query Rav Ada bar Ahavah from the latter case as to why the bird that was brought below the Chut ha'Sikra should not be Kasher anyway, even if it was an Olah, like Rav Ada explained. And we answer that - his ruling only applies to a case where one person is concerned, but in this case, how will Le'ah who is Chayav a Chatas, be Yotzei with Rachel's Olah (even according to him).

5)

(a)The Mishnah also discusses a case where Rachel and Le'ah required six birds between them - the above Olah and Chatas plus a second pair of birds each.

(b)Between them, they brought one Chatas and one Olah, one pair of unspecified birds and one pair of specified birds. Like in the previous case, if the Kohen brought all the birds above the Chut ha'Sikra, half of them are Olos. In a case where the Kohen brought half of them above and half of them below the Chut ha'Sikra, the Tana - invalidates all the birds except for the unspecified ones, one of which automatically becomes a Chatas, the other, an Olah ...

(c)... based on the Halachah that if the birds are not specified by the owner when he designates them, then they become specified when the Kohen designates them for the Avodah.

(d)To make up for the specified birds that are both Pasul - the two women will be obligated to purchase another pair of birds and to stipulate that the Olah is being brought on behalf of the one who previously brought a Chatas, and vice-versa.

6)

(a)We now ask on Rav Ada bar Ahavah the same Kashya that we asked on the previous Mishnah. We cannot answer like we did earlier, that the one woman will not be Yotzei her Chatas with the other's Olah (like we did there) - because we are speaking here, where the women did not specify which one receives which bird (as they did there).

(b)Nor can we answer by establishing the Mishnah in Kinim not like Rebbi Yehoshua - because the author of Kinim is basically Rebbi Yehoshua, as we will now proceed to prove.

7)

(a)The Mishnah in Kinim rules that if a pregnant woman makes a Neder to bring a Kan (a pair of birds, either pigeons or young doves) should she give birth to a boy, in the event that she does indeed give birth to a boy - she must bring two Kinin, one for the birth (an Olah and a Chatas), and one for her Neder (two Olos) ...

(b)... because a Chatas (even a Chatas ha'Of) can never be brought voluntarily.

(c)Assuming that she did not designate the four birds that she subsequently brings, when she hands them to the Kohen - he must bring three birds above the Chut ha'Sikra, and one below it.

8)

(a)The Tana then discusses what the Din will be if the Kohen - assuming that the woman gave birth be'Zov (thereby requiring two Kinin, each consisting of a Chatas and an Olah) brings two of the birds above the Chut ha'Sikra and two below it without consulting the woman -

(b)Assuming that ...

1. ... both Kinin comprise the same species (either pigeons or young doves) - the woman remains obligated to bring one bird of the same species as the bird that was brought as a Chatas.

2. ... they comprise two different species - she will have to bring two birds, one of each species ...

(c)... since the Tana is speaking where it is unsure which of the two species the Kohen brought first for her Chovah and which he brought last for her Neder (had this been clarified, she would only have had to bring the second bird of whichever species was brought last).

(d)If, in addition, she specified which species she is bringing for her Neder, but forgot what she said, then, assuming that ...

1. ... both Kinin comprise the same species - she then remains obligated to bring three birds, one of the same species that she brought the first time, and a Kan comprising the other species.

2. ... they comprise two different species - she still has to bring four birds, one of each species to complement the Chatas of whichever species the Kohen brought last, which is either a pigeon (to which she must add two young doves), or a young dove (to which she must add two pigeons). So she brings two pigeons and two young doves.
