(Mishnah): [Whether he did Ha'ara'ah or a full Bi'ah,] he acquired, and we do not distinguish different types of Bi'ah.

Question: What did he acquire [through an inferior Bi'ah]?

Answer #1 (Shmuel): He acquired only for matters mentioned in the Parshah [of Yibum] - to inherit the Mes' property, to forbid her to the brothers, and to permit her Tzarah l'Shuk.

Answer #2 (R. Yochanan): He acquired all matters.

(R. Yitzchak bar Elazar): They argue about Ha'ara'ah, but if he did full Bi'ah, all agree that he acquired all matters [even b'Shogeg or b'Ones].

(R. Masniyah): They argue about when she is still in her father's house, but if he had Bi'ah with her when she is in her husband's house, all agree that he acquired all matters.

Support (R. Yosi - Mishnah): If he entered her, she is like his wife in every way.

Question: May she eat Terumah [through an inferior Bi'ah, if the Yavam is a Kohen]?

Answer #1 (R. Ba citing Shmuel): It seems that if she ate Terumah in her husband's lifetime, she eats. If not, she does not eat.

Answer #2 (R. Yochanan): Even if she did not eat [in her husband's lifetime], she eats.

(R. Yosi): [Shmuel permits] even if [she did not eat in her husband's lifetime, just] she was permitted to eat.

A Beraisa supports this one (Shmuel), and a Beraisa supports this one (R. Yochanan);

Support (for Shmuel - Beraisa): If a Bas Yisrael Pikachas was married to a Kohen Cheresh, she does not eat Terumah. If he died and she fell to the Yavam, if he is a Pike'ach, she eats. If he is a Cheresh, she does not eat until she enters Chupah for Nisu'in.

Support (for R. Yochanan - Beraisa): If a Bas Yisrael Pikachas was Mekudeshes to a Kohen Pike'ach, and before he entered her to Chupah for Nisu'in, he became Cheresh or she became Chereshes, she does not eat Terumah. If he died and she fell to the Yibum, even if he is a Cheresh, she eats;

In this way, the Yavam has greater power her husband. A Cheresh Yavam permits her to eat [Terumah], but a Cheresh husband does not permit her to eat.

(Mishnah): Similarly, if one had Bi'ah with any Ervah in the Torah, e.g. a Kohen Gadol with a widow, a regular Kohen with a Chalutzah, a Yisrael with a Mamzeres or Nesinah or vice-versa, he disqualified [her].

We do not distinguish different types of Bi'ah;

(Gemara) Suggestion: "Almanah Lo Yikach" - perhaps he may rape her (the Torah forbids only through marriage)!

Note: Obviously, there is no Heter to rape! The Gemara suggests that if he rapes her, he does not transgress this Lav. (PF)

Rejection: "Lo Yechalel Zar'o b'Amav" (he may not profane his children. This is even without marriage.)

Suggestion: Perhaps one may do Ha'ara'ah (it cannot impregnate)!

Rejection: 'Lo Yachul' [would have forbidden profaning his children. Rather,] it says "v'Lo Yechalel" - even through rape, and even Ha'ara'ah.

Question: This is according to R. Akiva (in Toras Kohanim, he expounds the prefix Vov v'Lo Yechalel - HA'GAON RAV C. KANIEVSKY, SHLITA). According to R. Yishmael [who does not expound Vovim, how can we answer]?

Answer #1 (Beraisa - R. Yishmael): It says here Lekichah (marriage), and it says below Lekichah regarding all other Arayos. Just like Lekichah regarding all other Arayos, the Torah made Ha'ara'ah like full Bi'ah, also Lekichah here, we should make Ha'ara'ah like full Bi'ah.

Question (R. Chagai - Beraisa): Just like Lekichah regarding all other Arayos, the Torah made Ha'ara'ah like full Bi'ah, and the child is a Mamzer, also Lekichah here, we should make Ha'ara'ah like full Bi'ah, and the child is a Mamzer!

Answer #1 (R. Yosah): Why did the Torah say [Yechalel, to teach that the child is a] Chalal? Is not Mamzer greater [more Pasul] than Chalal? (Rather, it teaches that the child is a Chalal, and not a Mamzer.)

Answer #2 (to both questions - R. Bun bar Bisna citing R. Ba bar Mamal): It says here Lekichah (marriage), and it says below Lekichah regarding Shomeres Yavam. Just like Lekichah regarding Shomeres Yavam, the Torah made Ha'ara'ah like full Bi'ah and the child is Kosher, also Lekichah here, we should make Ha'ara'ah like full Bi'ah and the child is Kosher.

(R. Ba bar Mamal): Once he did Ha'ara'ah, he is liable for Bi'ah. Once the crown enters, he is liable for her due to Chalalah. When he finished his Bi'ah and ejaculated, he is liable for profaning his seed. (We explained this like SHIREI KORBAN, Halachah 1.)
