(R. Yakov bar Acha citing R. Yoshiyah): The 11th generation of a Mamzer is Kosher according to R. Shimon. He does not expound [the Gezeirah Shavah of "Asiri-]Asiri" [to Amoni u'Mo'avi, about which it explicitly says "Ad Olam"].

(Beraisa - R. Elazar b'Ribi Shimon): The 11th generation of a Mamzer - males are forbidden, and females are permitted;

(We learn from the Gezeirah Shavah to Amoni u'Mo'avi.) Just like there, males are forbidden and females are permitted, also here, males are forbidden, and females are permitted.

(R. Shmuel brei d'R. Yosi bei R. Bun): R. Elazar b'Ribi Shimon holds like R. Meir;

Just like R. Meir says that a Gezeirah Shavah [teaches all laws like] in the [other] place where it is written (Dun Minah u'Minah), R. Elazar b'Ribi Shimon says that a Gezeirah Shavah [teaches all laws like] in the place where it is written.

Just like there, males are forbidden and females are permitted, also here, males are forbidden, and females are permitted.

Question: If so, [we should learn from Amoni u'Mo'avi also that females are permitted] even immediately!

Answer: [We needed to learn from the Gezeirah Shavah] only past 10 generations (PNEI MOSHE).

Question (to R. Eliezer): What is the law of the 11th generation of a Mamzer?

Answer (R. Eliezer): Bring to me a third generation [Mamzer], and I will permit him!

What is the reason of R. Eliezer? [Mamzerim] do not live [to three generations].

R. Eliezer holds like R. Chaninah, for R. Chaninah said that once in 60 or 70 years, Hash-m brings a plague to the world, and it consumes all Mamzerim and takes [also some] Kesherim with them, lest He publicize the sinners.

This is like R. Levi said in the name of Reish Lakish, "bi'Mkom Asher Tishachet ha'Olah Tishachet ha'Chatas Lifnei Hash-m" - not to publicize sinners (people do not know that it is a Chatas; they can think that it is an Olah, since both are slaughtered in the north.)

Note: Even though Olah is male and Chatas is female, the gender of lambs and kids is not easy to discern without crouching down.

Question: Why does it say "v'Gam Hu Chacham va'Yavei Ra" - is it not reasonable to say rather 'v'Gam Hu Chacham va'Yavei Tov'?!

Answer: This teaches that even evil that Hash-m brings to the world, He brings it with Chachmah.

[The above verses continues] "v'Es Devarav Lo Hesir" (he did not remove His Dever, i.e. plague) - what is the reason? "V'Kam Al Beis Mere'im v'Al Ezras Po'alei Aven" (it eradicates Mamzerim, who come from sinners, and those who helped sinners or did not protest against them).

(Rav Huna): A Mamzer does not live more than 30 days.

When R. Ze'irah came here (to Eretz Yisrael), he heard voices calling out '[this is a] Mamzer', '[this is a] Mamzeres'.

R. Ze'irah (to them): Can this be? If so, Rav Huna's teaching is false, for Rav Huna said that a Mamzer does not live more than 30 days!

Note: I.e. the people calling out 'Mamzer' were not discussing babies within 30 days. How could R. Ze'irah think that no Mamzer lives 30 days? The Torah forbids Bi'as Mamzer to Kehal Hash-m. Bi'ah applies only after the age of three or nine years!

R. Yakov bar Acha (to R. Ze'irah): I was with you when R. Ba cited Rav Huna citing Rav, to say that a Mamzer does not live more than 30 days. When is this? It is when he is not well known, but if he is well known, he can live.

(R. Yosi citing R. Yochanan): Even in the future, Hash-m will deal with (eradicate Pesulim from) only Shevet Levi. What is the source? "Va'Yashov Metzaref u'Metaher Kesef v'Tiher Es Bnei Levi v'Zikek Osam..."

(R. Ze'orah): This is like a man who drinks from a clean cup. (Leviyim serve Hash-m, so they must be purified.)

(R. Hoshayah): Because we are Leviyim, should we lose (our Mamzerim will be publicized)?!

(R. Chaninah brei d'R. Avahu): Even in the future, Hash-m will do Tzedakah with [Shevet Levi, i.e. overlook Pesulim]. What is the source? [The above verse concludes] "v'Hayu la'Shem Magishei Minchah bi'Tzdakah."

(R. Yochanan): Any family in which a Pasul was Nishtaka (entered and was forgotten), we are not meticulous [to expose it].

Support (Reish Lakish - Mishnah): The family of Beis Tzerifah was in Ever ha'Yarden. Ben Tziyon distanced it by force. There was another family, and he brought it close (caused people to consider it to have proper lineage) by force. Even so, Chachamim did not want to publicize them;

However, Chachamim hand over [the truth about them] to their children and Talmidim twice in seven years.

(R. Yochanan): I swear, I know them, and Gedolei ha'Dor Nishtak'u with them!

(R. Yehoshua ben Levi): There were 5000 slaves of Pashchor ben Amar the Kohen, and all of them Nishtak'u into Kehunah! These are the brazen Kohanim.

(R. Lazar): The primary lineage [of Kohanim] is in brazen ones - "v'Amcha k'Merivei Kohen."

(R. Avahu): Thirteen cities Nishtaka with Kusim in days of royal decrees against Torah. They say that the city of Meishan is among them.
