(Mishnah): The daughter of a male Chalal is forever forbidden to Kehunah.

If a Yisrael married a Chalalah, his daughter is permitted to Kehunah. If a Chalal married a Bas Yisrael, his daughter is forbidden to Kehunah.

Rebbi Yehudah says, the daughter of a male convert is like the daughter of a Chalal.

R. Eliezer ben Yakov says, if a Yisrael married a convert, or convert married a Bas Yisrael, the daughter is permitted to Kehunah, but the daughter of two converts is forbidden to Kehunah.

The law is the same for converts and freed slaves. Even after 10 generations, the daughter is forbidden to Kehunah unless her mother is a Bas Yisrael.

Rebbi Yosi says, even the daughter of two converts is permitted to Kehunah.

(Gemara) Question: Why does it say (a male Chalal's daughter is) forever (forbidden to Kehunah)?

Answer: One might have thought that her Isur is like that of Mitzriyim and Edomim, i.e. until three generations. 'Forever' teaches that this is not so.

(Mishnah): If a Yisrael married a Chalalah...

Question: What is the source for this?

Answer (R. Yochanan): It says "(a Kohen) will not profane his seed among his nation", and "(a Kohen) will not become Tamei among his nation";

Just like (the Isur of) Tum'ah applies only to male Kohanim, not females, also profaning seed applies only to males.

Question: If so, the daughter of a Kohen Gadol (from a widow) should be Kesheirah!

Answer: It does not say 'he will not profane his son', rather, "he will not profane his seed." This includes his daughter.

Question: The daughter of a Kohen Gadol's son should be Kesheirah!

Answer: "He will not profane his seed" equates his seed to him;

Just like his daughter is disqualified, also his son's daughter.

Question: The daughter of a Kohen Gadol's daughter should be disqualified!

Answer: This cannot be, for then the Gezeirah Shavah between Tum'ah and profaning seed would not teach anything!

(Mishnah): If a Chalal married a Bas Yisrael, his daughter is forbidden to Kehunah.

Question: The Reisha taught this! The daughter of a male Chalal is forever forbidden to Kehunah!

Answer: Since we needed to teach about a Yisrael who married a Chalalah, we repeated a Chalal who married a Bas Yisrael for parallel structure.

Our Mishnah is unlike R. Dostai ben Yehudah.

(Beraisa - R. Dostai ben Yehudah): Just like Bnei Yisrael purify Chalalos (i.e. their children are Kesheirim), also Benos Yisrael purify Chalalim.

Question: What is R. Dostai's reason?

Answer: It says "he will not profane his seed among his nation" - (when his seed marries) among one nation (i.e. within Kehunah), the children are profaned. Among a different nation (outside Kehunah), the children are not profaned.

(Beraisa) Question: It says "he will not profane his seed." What is the source that also his wife is profaned?

Answer: We learn from a Kal va'Chomer: his children, who didn't sin, are profaned. His wife sinned, all the more so she is profaned!

Question: Her husband disproves this. He sinned, but he is not profaned!

Answer #1: That is no disproof, for a (Kosher) Kohen never becomes profaned. A woman can be profaned (e.g. through Bi'ah with a Mamzer), she is profaned here!

Answer #2: If you prefer, "he will not profane" refers to one who was Kosher, and now becomes profaned, i.e. his wife.

Question: What objection might we have to Answer #1?

One can ask that his seed was created through sin (therefore it is profaned, but his wife was not). Therefore, we give Answer #2.

(Beraisa): Who is a Chalalah? It is anyone born from disqualified parents.

Question: What does this mean?

Suggestion: It refers to a woman forbidden to her husband.

Rejection: One may not remarry his divorcee (if she married someone else in between), but the children are Kesheirim!

"To'evah Hi" - she is an abomination, but her children are not abominations.

Answer #1 (Rav Yehudah): It means, anyone born from (a Kohen and) a woman forbidden to Kohanim.

Objection: A widow (who had Bi'ah with a Kohen Gadol), Zonah or divorcee (who had Bi'ah with a Kohen) becomes a Chalalah, even if she was not born from women forbidden to Kohanim!

Answer #2 (Rabah): The Beraisa asks 'who is the Chalalah the Torah mentions, who was never Kesheirah? It is anyone born from a woman forbidden to Kohanim.'

Question: What does 'the Torah mentions' refer to?

Answer (Rav Yitzchak bar Avin): We ask 'who is the Chalalah explicit in the Torah ("Kohanim will not marry... a Chalalah" - she was a Chalalah even before marrying a Kohen) that Chachamim need not explain? It is anyone born from a woman forbidden to Kohanim.

(Beraisa): If a Kohen Gadol married three widows, he is liable only once. If he married three divorcees he is liable only once;

If he married a widow who is a divorcee, a Chalalah and a Zonah and the events (which made her a widow, divorcee, Chalalah and Zonah) occurred in this order, he is liable for each one;

If the events occurred in the reverse order, e.g. she had Bi'ah with Ervah, then with a Kohen, then she was divorced, and then widowed, he is liable only once.

Question: What is the case of three widows?

If he had Bi'ah with the widows of Reuven, Shimon and Levi, why is he liable only once? They are different women, and widows of different men!

Answer: Rather, he had Bi'ah three times with one widow.

Question: What is the case?

If he was warned only once, obviously, he is liable only once!

Answer #1: Rather, he was warned each time.

Objection: If so, why is he liable only once?

(Mishnah): If a Nazir drank wine all day, he is lashed only once. If he was warned repeatedly, he is liable for each warning.

Answer #2: He had Bi'ah with Reuven's widow, who is also Shimon's widow and Levi's widow.

One might have thought that since she is the widow of different men, he is liable for each. The Beraisa teaches that this is not so.

Question: The Beraisa discusses a widow who is a divorcee, a Chalalah and a Zonah. What does the Tana hold regarding Isur Chal Al Isur (does a second Isur takes effect on something already forbidden)?

If he holds that Isur Chal Al Isur, he should be liable for each even in these occurred to her in the reverse order!

If he holds that Ein Isur Chal Al Isur, even in this order he should be liable only once!

Answer (Rava): Normally, he holds that Ein Isur Chal Al Isur. If the new Isur is Mosif (forbids the Isur to more people or actions), it takes effect.

A widow is forbidden to a Kohen Gadol and permitted to a regular Kohen. When she was divorced, she became forbidden to all Kohanim. Therefore, the Isur of a divorcee takes effect also for a Kohen Gadol;

A divorcee may eat Terumah (e.g. a Bas Kohen without children). When she became a Chalalah, she became forbidden to eat Terumah. Therefore, the Isur of a Chalalah takes effect also for a Kohen Gadol.

Question: Zonah does not add to the Isur Chalalah!

Answer (R. Chana bar Rav Katina): Since Znus forbids a woman even to a Yisrael (i.e. adultery), it is considered Mosif to Chalalah (which applies only to Kehunah).

(A reciter of Beraisos): "He (a Kohen Gadol) will not take (a widow)" applies only to a woman to whom (originally) applied "he will take";

This excludes a Kohen Gadol's widowed sister (he is liable only for Bi'ah with a sister, not for Bi'ah with a widow).

Version #1 (Rav Sheshes): This is like R. Shimon, who holds that Ein Isur Chal Al Isur.

(Beraisa - R. Shimon): One who eats a Neveilah on Yom Kippur is exempt (from Kares if it was a Neveilah before Yom Kippur).

According to Chachamim, Isur Chal Al Isur (the Isur of a widow takes effect on his sister)!

Rejection: It is even like Chachamim. They said only that a severe Isur (Yom Kippur) is Chal on a light Isur (Neveilah), but a light Isur is not Chal on a severe Isur!

Version #2: The Beraisa is like Chachamim. They say only that a severe Isur is Chal on a light Isur, but a light Isur is not Chal on a severe Isur;

It cannot be like R. Shimon. He holds that even a severe Isur is not Chal on a light Isur, so he would not need to teach that a light Isur is not Chal on a severe Isur!

Rejection: It can even be like R. Shimon. One might have thought that the special Isurim of Kohanim are different (they are Chal on severe Isurim). The Beraisa teaches that this is not so.

Question (Rav Papa): If a Yisrael had Bi'ah with his sister, this makes her a Zonah. Does it also make her a Chalalah?

If Chayavei Lavin (such like a widow to a Kohen Gadol) makes a woman a Chalalah, all the more so Chayavei Kerisus!

Or, perhaps Chalalah results only from Isurim of Kehunah.

Answer (Abaye): Chalalah results only from Isurim of Kehunah.

(Beraisa): Had the Torah not said that a divorcee is forbidden to a Kohen Gadol, we could have learned it from a Kal va'Chomer: a divorcee is forbidden even to a regular Kohen, all the more so, to a Kohen Gadol!

The Torah wrote the Isur to teach that just like the Isur of a divorcee is distinct for a regular Kohen from the Isurim of Chalalah and Zonah (it is written by itself, to teach that one gets separate lashes for it), also for a Kohen Gadol.

Objection: Obviously, a Kohen Gadol should have all the Isurim of a regular Kohen!

Correction: Rather, just like the Isur of a divorcee is distinct for a regular Kohen from the Isurim of Chalalah and Zonah, also the Isur of a widow for a Kohen Gadol is distinct from the Isurim of a divorcee, Chalalah and Zonah.

Question: Why did the Torah need to forbid a Chalalah to a Kohen Gadol (she is forbidden even to a regular Kohen)

Answer: This teaches that Chalalah comes only from Isurim of Kehunah.

Question: Why did the Torah need to forbid a Zonah to a Kohen Gadol?

Answer: This is for a Gezeirah Shavah Zonah-Zonah from a regular Kohen;

Just like a Kohen Gadol's children from a Zonah are Chulin (Chalalim), also a regular Kohen's.

(Rav Ashi): Therefore, if a Kohen has Bi'ah with his sister, he makes her a Zonah, not a Chalalah.

If he has a second act of Bi'ah with her, this makes her a Chalalah (for she is now a Zonah, one of them special Isurei Kehunah).
