(Mishnah): Some women are permitted to their husbands and forbidden to their Yevamim. Some are forbidden to their husbands and permitted to their Yevamim. Some are permitted to both. Some are forbidden to both;

The following are permitted to their husbands and forbidden to their Yevamim:

A regular Kohen who married a widow, and his brother is a Kohen Gadol;

A Chalal who married a Kesherah, and his brother is (a Kohen) Kosher;

A Yisrael who married a Bas Yisrael, and his brother is a Mamzer;

A Mamzer who married a Mamzeres, and his brother is a Yisrael. [All of these] are permitted to their husbands and forbidden to their Yevamim.

(Gemara) Question (R. Nicha bar Sava, to R. Yonah): Why does it say [a regular Kohen who] Nasa (had Nisu'in with a widow)? Even if he was Mekadesh [she is forbidden to his brother, a Kohen Gadol]! Why does it say a widow? Even if he married a Besulah (when she falls to Yibum, she is a widow and is forbidden to his brother)!

Question: Are these the only ones? There is the Tzarah of a Sotah - she is permitted to her husband and forbidden to the Yavam!

If [Reuven's] brother (Shimon) had Bi'ah with (i.e. married) the sister of [Reuven's] Chalutzah (she had fallen from a third brother) - she is permitted to her husband (Shimon), and forbidden [mid'Rabanan] to the Yavam (Reuven)!

(Mishnah): If a Kosher married a Kesherah, and his brother is a Chalal, she is permitted to her husband and forbidden to the Yavam.

Question: Didn't R. Yosi bei R. Bun say in the name of Rav that a convert, freed slave and Chalal are permitted to Kohanos? (If so, she is permitted also to the Yavam!)

Answer #1: This supports R. Yonah, for R. Yonah said that Rebbi's Klalim are not Klalim (not all cases are correct).

Support [It omitted also] a Chalal who married a Kesherah, and his brother is (a Kohen) Kosher. She is permitted to her husband and forbidden to the Yavam.

Rebuttal (and Answer #2): [The text of] our Mishnah should say a Chalal who married a Kesherah, and his brother is (a Kohen) Kosher. (She is permitted to her husband and forbidden to the Yavam, for her husband disqualified her through Bi'ah. We explained this like MEICHAL HA'MAYIM.)

Note: In the conclusion, R. Yonah meant that Rebbi's Klalim did not teach all the cases.

(R. Yosi bei R. Bun citing Rav): A convert, freed slave and Chalal are permitted to Kehunah (a Bas Kohen).

Question: What is the reason?

Answer: Kesherim (Kosher Kohanim) are warned about [may not marry] Pesulos, and Pesulos [are warned about] Kesherim, but Pesulim (Chalalim) are not [warned about] Kesheros, and not Kesheros about Pesulim. (We explained this like HA'GAON RAV C. KANIEVSKY, SHLITA.)

Question (Beraisa): "Lo Yikachu... Lo Yikachu" - (the repetition teaches that also) the woman is warned about the man.

Assumption: We thought to say that [this means that also] Kesheros [are warned] about Pesulim.

Answer: This is not so. [Rather,] Pesulos [are warned] about Kesherim.

(Mishnah): The following are permitted to their Yevamim and forbidden to their husbands:

A Kohen Gadol who was Mekadesh a widow, and his brother is a regular Kohen;

A Kosher (Kohen) who married a Chalalah, and his brother is a Chalal;

A Yisrael who married a Mamzeres, and his brother is a Mamzer;

A Mamzer who married a Bas Yisrael, and his brother is a Yisrael.

(Gemara): [The case of widow to a Kohen Gadol] is only when he was Mekadesh her. If he had Bi'ah with her, she is disqualified [to all Kohanim] through Bi'ah.

Question: Our Mishnah taught 'these are forbidden to their husbands and permitted to their Yevamim. Are these the only cases? There are more!

One who remarried his divorcee after she remarried, she is forbidden to her husband and permitted to her Yavam!

If one had Bi'ah with (married) the sister of his Chalutzah - she is forbidden to her husband and permitted to her Yavam!

If a Petzu'a Daka married a Kesherah, and his brother is Kosher - she is forbidden to her husband and permitted to her Yavam!

Answer: This supports R. Yonah, for R. Yonah said that Rebbi's Klalim are not Klalim (he did not teach all the cases).

(Mishnah): The following are forbidden to these (their husbands) and these (their Yevamim):

A Kohen Gadol who married a widow, and his brother is a Kohen Gadol or a regular Kohen;

A Kosher (Kohen) who married a Chalalah, and his brother is Kosher;

A Yisrael who married a Mamzeres, and his brother is a Yisrael;

A Mamzer who married a Bas Yisrael, and his brother is a Mamzer. [All these] are forbidden to these and these.

All other women are permitted to their husbands and their Yevamim.

Question: Are these the only ones? A Sotah is forbidden to this (her husband) and to this (the Yavam)!

A Chalutzah is forbidden to this and to this!

If a Petzu'a Daka married a Kesherah, and his brother is a Petzu'a Daka - she is forbidden to this and to this!

Answer: This supports R. Yonah, for R. Yonah said that Rebbi's Klalim are not Klalim (he did not teach all the cases).
