SEMICHAH ON ASHAM METZORA
Support (for Ula - Beraisa): Shechitah must always be Tekef l'Semichah, except for Asham Metzora, for which Semichah is by Sha'ar Nikanor;
The Metzora cannot enter the Azarah until the blood of the Asham is put on him and the blood of the Chatas is Nizrak.
If Bi'ah b'Miktzas were not Bi'ah, he could stick his hands in and do Semichah!
Version #1 - Rejection (Rav Yosef): The Tana is R. Yosi b'Rebbi Yehudah, who says that Tzafon (the north half of the Azarah, where Kodshei Kodoshim must be slaughtered, begins to the north of the Mizbe'ach, it) is far (22 Amos west) from the end of Ezras Nashim. (Therefore, the Metzora's hands cannot reach to the place of Shechitah.)
Question: (If Bi'ah b'Miktzas is not Bi'ah,) why didn't they make an opening in the north wall of the Azarah (in line with the Mizbe'ach, so the Metzora could stand outside and enter his hands for Semichah in a valid place for Shechitah)?
Answer (Abaye and Rava): "Ha'Kol bi'Chsav mi'Yad Hash-m... Kol Mal'achos ha'Tavnis" - Hash-m told David the exact form of the Mikdash. We cannot change anything.
Version #2 - Rejection (Rav Yosef): To do Semichah in the Azarah, one must enter the majority of his body and his head into the Azarah.
Question: What is the reason?
Answer: One must press down with all his strength.
Therefore, the Metzora cannot do Semichah from Sha'ar Nikanor. (End of Version #2)
Question: What is the Tana's opinion regarding Asham Metzora?
Version #1 - Answer: The Torah requires Semichah, and Shechitah must be Tekef after Semichah.
Rejection: If so, the Torah allows the Metzora to fully enter the Azarah (even though this is normally forbidden)!
Defense of Answer #1 (Rav Ada bar Ahavah): Mid'Oraisa, he should enter. Chachamim decreed not to, lest he enter further than necessary (and be Chayav Kares).
Version #2 - Answer (Rav Ada bar Ahavah): The Torah requires Semichah, but Shechitah need not be Tekef l'Semichah.
Question (Beraisa): "V'Samach... v'Shachat" - just like only a Tahor can do Semichah, only a Tahor can slaughter.
If mid'Oraisa Shechitah need not be Tekef, a Tamei can do Semichah (outside the Azarah, and the Korban will be brought in for Shechitah)!
Correction - Answer (Rav Ada bar Ahavah): The Torah does not require Semichah of Asham Metzora, but (when Semichah is required), Shechitah must be Tekef l'Semichah.
(Ravina): Ula taught (32b, in the name of Reish Lakish, that Bi'as Mikdash b'Miktzas is Bi'ah) about lashes, but not about Kares.
(Ravin): Reish Lakish expounded to teach about a Tamei who touched Kodesh (and not about Bi'as b'Miktzas);
(Reish Lakish): If a Tamei touched Kodesh, he is lashed;
He learns from "b'Chol Kodesh Lo Siga".
(R. Yochanan): He is not lashed.
"B'Chol Kodesh..." refers to Terumah.
Question: Reish Lakish says that the verse forbids a Tamei to eat Kodesh!
Question: Which verse forbids a Tamei to eat Kodesh?
Answer #1 (Reish Lakish): "B'Chol Kodesh Lo Siga."
Answer #2 (R. Yochanan - Bardela - Beraisa): We learn a Gezerah Shavah "Tum'aso- Tum'aso" from a Tamei who entered the Mikdash. Just like that is Chayavei Kerisus and a verse forbids it, also a Tamei who eats Kodesh.
Answer: Reish Lakish learns both from the verse;
Since it says "Siga" (touching), it forbids touching;
"B'Chol Kodesh Lo Siga... (v'El ha'Mikdash Lo Savo)" forbids (a Tamei) to eat Kodesh, for it is equated to entering the Mikdash.
Support (for Reish Lakish - Beraisa): "B'Chol Kodesh Lo Siga" forbids eating.
Question: Perhaps it forbids touching!
Answer: "...V'El ha'Mikdash Lo Savo" - the Isur (Lo Siga) of Kodesh is equated to entering the Mikdash. Just like one is Chayav Misah b'Yedei Shamayim for the latter (it is included in Kares), also Lo Siga, i.e. eating Kodesh while Tamei;
One is not Chayav Misah for touching.
