(Mishnah): An Arusah (a wife between Kidushin and Nisu'in) or a Shomeres Yavam (she is awaiting Yibum) does not drink or receive a Kesuvah - "Asher Tisteh Ishah Tachas Ishah v'Nitme'ah" excludes an Arusah and a Shomeres Yavam;

A widow married to a Kohen Gadol, a divorcee or Chalutzah (one who did Chalitzah) married to a regular Kohen, a Mamzeres (one who descends from Arayos forbidden by Kares) or Nesinah (one of the seven Kena'ani nations) married to a Yisrael, or a Bas Yisrael married to a Mamzer or Nasin, she does not drink or receive a Kesuvah..

(Gemara) Question: [Since an Arusah does not receive a Kesuvah, this shows that Kinuy took effect. Since she is not excluded from Kinuy,] he should be Mashkeh her!

Answer: It is a Gezeiras ha'Kasuv "v'Hevi ha'Ish Es Ishto El ha'Kohen." (Ishto connotes Nesu'ah.)

Question: [If so], he should not [be able to be] Mekanei her!

Answer: The Torah said "v'Kinei Es Ishto" [and repeats] "v'Kinei Es Ishto." [An exclusion after an exclusion comes to include, i.e.] even a partial wife.

Assumption: Our Mishnah is unlike Beis Shamai, for Beis Shamai say that [if a Sotah's husband died], she receives her Kesuvah and does not drink. (They consider a document as if it was collected. Also here, since she cannot drink, she should receive her Kesuvah!)

Rejection (R. Yosi): There, Beis Shamai's reason is, she can say 'give to me my husband, and I will drink!' However, here she knew that an Arusah cannot drink. Why did she enter herself into this great Safek? It was in order to forfeit her Kesuvah.

Question (R. Yehudah): Just like you say there, "v'Kinei Es Ishto... v'Kinei Es Ishto" [includes] even a partial wife, you should say similarly "Tachas Ishech" [includes] even a partial wife (also this is repeated)!

Question: What is the law [of Kinuy of an Arusah or Shomeres Yavam]?

Answer: If he was Mekanei her while she was an Arusah, and he entered her (Nisu'in) and she was secluded, he is Mashkeh her based on his Kinuy;

If he was Mekanei her while she was a Shomeres Yavam, and he entered her (Yibum) and she was secluded, he is Mashkeh her based on his Kinuy;

If he was Mekanei her while she was an Arusah, and she was secluded, and he entered her (Yibum) and she was secluded - if he knew [of seclusion before he did Nisu'in], she is divorced and gets a Kesuvah. (The Yerushalmi holds that one can pardon Kinuy even after seclusion. Making Nisu'in shows that he pardoned. If he says that he did not, he must divorce her and pay her Kesuvah.) If not, she is divorced and does not get a Kesuvah (it was a Mekach Ta'os).

If her husband was Mekanei her and he died, and she fell in front of the Yavam, and he entered her and she was secluded - he is Mashkeh her based on his [brother's] Kinuy;

If her husband was not Mekanei her and he died, and she fell in front of the Yavam, and he was Mekanei her and before he entered her he died and she fell [to Yibum] to his brother, he is not Mashkeh her, for she fell to him only due to his first brother (and his first brother was not Mekanei her);

However, if the Yavam was Mekanei her and entered her and he died, and she fell in front of the [second] Yavam, and he entered her and she was secluded, he is Mashkeh her based on [the first Yavam's] Kinuy (since she fell from him. We explained this like PNEI MOSHE.)

(Mishnah): An Ailonis or Zekenah does not drink or receive her Kesuvah, for it says "v'Niksah v'Nizre'ah Zara" - one who is proper to bear children. This excludes this one, who is not proper to bear children.

Question: A widow to a Kohen Gadol is proper to bear children (yet she does not drink)!

Answer #1: She is different, for it says "v'Lo Yechalel Zar'o b'Amav." (Her children from him are Chalalim. They are not proper Zera.)

Question (Mishnah): A Mamzer can disqualify [his grandmother from Terumah, e.g. if she is a Bas Kohen widowed from a Yisrael and her children died] or permit to eat (if his grandmother is a Bas Yisrael who married a Kohen. This shows that a Mamzer is called Zera), and here you say so?!

Answer (R. Tanchuma): There it says "v'Zera Ein Lah" - at all (even Pasul Zera is called Zera). However, here it refers to Kosher Zera, and not Pasul Zera.

Answer #2 (R. Yosi bei R. Bun): The water comes only to permit her to her husband. This (widow to a Kohen Gadol), since she is forbidden to him, [in any case] we tell him to divorce her.
