(R. Yakov bar Ada bar Aslai citing R. Lazar): The Halachah follows R. Meir in Gitin (if the Shali'ach did not say the declaration and she remarried, the child is a Mamzer).

R. Ze'ira was staring at him [in astonishment]. R. Yakov said, why do you stare at me?!

It was said that the Halachah follows the lenient opinion in mid'Rabanan laws. [And even if] you want to say [that we are stringent] when an individual argues with an individual, when an individual argues with Chachamim [who are lenient], no! Here, [you are stringent] even like an individual against Chachamim! (We explained this like RASHBA 5b, PNEI MOSHE.)

(R. Chiyah citing R. Ba): If one sold his slave to Ako, he goes free (like the fine for one who sold his slave to Chutz la'Aretz.)

Question (R. Yishmael, the father of R. Yudan): Is this even if he sold from [the part of] Ako [in Eretz Yisrael] to [the part of] Ako [in Chutz la'Aretz]?

Answer: This is like R. Yakov bar Acha said in the name of R. Ami. From two episodes of Rebbi, we learn that Ako is partially in Eretz Yisrael, and is partially in Chutz la'Aretz.

Rebbi was in Ako. He saw them eating clean bread (they soak the wheat before grinding it, which makes it able to receive Tum'ah). He asked them, why do you soak?

Note: One may not cause Tum'ah to Peros of Eretz Yisrael. This shows that Rebbi considers [at least part of] Ako to be in Eretz Yisrael. The other episode is brought below, at the end of this Halachah.

People of Ako: A Talmid came here, and ruled for us that Mei Beitzim is not Machshir. We cook eggs, and soak [wheat] the water!

They thought that Mei Beitzim is water in which eggs were cooked. [The Talmid] did not say so, rather, that egg white (is not Machshir).

(R. Yakov bar Acha): From that time, they decreed that a Talmid may not give rulings [without permission, lest he not clarify his words].

(R. Chunah citing R. Chuna): If a Talmid ruled [without permission], even if he ruled correctly, his ruling is invalid.

(Beraisa): If a Talmid ruled in front of his Rebbi, he is Chayav Misah.

(Beraisa - in the name of R. Eliezer): Nadav and Avihu died only because they ruled Halachah in front of Moshe their Rebbi.

A case occurred in which a Talmid ruled in front of his Rebbi, R. Eliezer. [R. Eliezer] said to Eima Shalom, his wife, 'he will not live the entire week.' He did not finish the week before he died.

His Talmidim: Rebbi, are you a Navi?!

R. Eliezer: I am not a Navi, and not a Ben (one preparing to become) a Navi. However, I have a tradition that any Talmid who rules in front of his Rebbi is Chayav Misah. (Presumably, his tradition included that he will die within the week. If not, it is as if he cursed him to die promptly! - PF)

(Beraisa): It is forbidden for a Talmid to rule in front of his Rebbi until he is distanced from him 12 Mil (a Mil is 2000 Amos, about a kilometer), like the size [length and width] of Machaneh Yisrael.

Question: What is the source [that Machaneh Yisrael is 12 Mil]?

Answer: "Va'Yachanu Al ha'Yarden mi'Beis ha'Yeshimos Ad Avel ha'Shitim b'Arvos Mo'av" - how far is [from mi'Beis ha'Yeshimos to Avel ha'Shitim]? It is 12 Mil, like Machaneh Yisrael.

This is like [the case of] R. Tanchum bar Yirmeyah. He was in Chefer, and they asked him [questions], and he ruled;

They said to him, Rebbi, did you not teach us that it is forbidden for a Talmid to rule in front of his Rebbi until he is distanced from him 12 Mil, like Machaneh Yisrael? R. Mana, your Rebbi, sits in Tziporin!

R. Tanchum: [Punishments] should come upon me [if it is not true] that I did not know.

From that time [and onwards], he did not rule [there].

Note: We now bring the second episode of Rebbi, which shows that he holds that part of Ako is Chutz la'Aretz.

Rebbi was in Ako. He saw a man past the rock [of Ako. Rebbi] said to him, are you not the son of Ploni?! Was your father not a Kohen?! (Why are you in Chutz la'Aretz? Chachamim decreed Tum'as Mes on Chutz la'Aretz!)

The man: My father's eyes were lofty. He married a woman not proper for him, and he profaned [me. I am a Chalal, who may become Tamei.]

Question: Cities in the Techum of Tziporin that are close to Ako, and cities in the Techum of Ako that are close to Tziporin, how do you consider them [regarding Gitin - PNEI MOSHE] - like Ako or like Tziporin?
