Question: What forced him to say so? He should say that they argue about Rav Hamnuna's law, and [Shmuel ruled like] all of R. Yosi's opinion!

Answer: It is unreasonable to him to say that they argue about Rav Hamnuna's law, because we say in Sotah (18b) that the Halachah does not follow Rav Hamnuna.

Implied question: Why didn't he say that they argue about whether or not Kidushin Tofsin b'Yevamah?

Answer: It is because they already argued about this.

Explanation (Ri): The one who says that he has a Ma'amar holds that he does not have Get. Ma'amar is preferable, for it is in place of Bi'ah, but Get is in place of Chalitzah;

Bi'ah is preferable to Chalitzah, for it is uniform. [It disqualifies] at the beginning or end, but Chalitzah does not.

Shmuel holds that he has a Get. All the more so he has a Ma'amar!

Explanation (Ri): R. Meir holds that he has Chalitzah, and all the more so Bi'ah. Rabanan hold that he has only Bi'ah, but not Chalitzah.

The Mishnah and Beraisa above, which say that a nine year-old disqualifies to the brothers in one way, must be like Rabanan;

According to R. Meir, Chalitzah is uniform [it always disqualifies], just like Bi'ah. He said that Chalitzah of a nine year-old boy is like an adult's Get. An adult's Get disqualifies even at the end.

Implied question: Shmuel and R. Elazar argue in Gitin (24b). Shmuel says that Chalitzah of a minor is Pasul and disqualifies, and R. Elazar says that it does not disqualify. (According to whom do they argue?)

Suggestion #1: They argue according to Rabanan. Shmuel holds that according to Rabanan, it disqualifies at the beginning, and R. Elazar says that it does not disqualify even at the beginning!

Rejection: You are forced to say that Shmuel agrees that Rabanan hold that he does not have Chalitzah at all;

Below (105b), on the Mishnah "Chalitzah of a minor is Pasul", Shmuel said "this is R. Meir's opinion. Chachamim say that his Chalitzah has no effect"!

Suggestion #2: They argue according to R. Meir.

Rejection: Here, he explicitly says that they made Chalitzah of a nine year-old like an adult's Get!

Answer: Rather, they argue about the Mishnah below (105b). Shmuel establishes it like R. Meir, and R. Elazar establishes it like Rabanan.

Assertion (Ri): Even though Rabanan did not enact Nisu'in for a minor, it is not forbidden. It is not considered Bi'as Zenus.

Support: It is even considered a Mitzvah to marry a woman to one's minor son, like it says in Sanhedrin (76b) 'the verse says about one [who does so] "v'Yadata Ki Shalom Ohalecha..."'

Explanation: "Kar'u" connotes that they intentionally tore it.

Explanation: When his Neshamah is in the Yeshiva above, his lips move in the grave, as if they speak. It turns out that at once, he dwells in two worlds.
