(Beraisa - in the name of R. Eliezer): Lulav and its Machshirim override Shabbos.

(R. Yonah): Our Mishnah is understood [according to this. Because Milah itself is Melachah, R. Eliezer permits to do Melachah even for its Machshirim - YALKUT MAHARI'ACH.]

(Beraisa): A case occurred, and Rebbi ruled like R. Eliezer.

Question (R. Yochanan citing Rabanan): Why did Rebbi deem it proper to abandon Chachamim and do like R. Eliezer?

Answer (R. Hoshayah): I asked R. Yehudah the Mohel, and he told us that [Rebbi permitted] in a Mavuy she'Eino Mefulash [and they did not make Shituf. It was not only like R. Eliezer. All permit!]

Objection: A Mishnah teaches that one may not move (transfer) from it (the Mavuy) to the houses, or from the houses to it! (If so, Rebbi's Heter was only like R. Eliezer.)

Answer (R. Avahu): [Rebbi permitted] when the baby and the knife were Shoves (began Shabbos) in the Mavuy (there was no need to transfer from houses to the Mavuy).

Question: Is it not forbidden to carry in the entire Mavuy?

Question (to R. Yosi): Just like it was taught that Kelim that were Shoves in the Chatzer, one may move them in the entire Chatzer - do we similarly say that Kelim that were Shoves in the Mavuy, one may move them in the entire Mavuy?

They asked him amidst (while learning) Shabbos, and he did not answer, for R. Yosi said every matter only in the proper place.

Answer #1: When they came to [learn] Eruvin, he told them in the name of R. Yochanan that Kelim that were Shoves in the Mavuy, one may move them in the entire Mavuy. And similarly, Kelim that were Shoves in the Chatzer, one may move them in the entire Chatzer.

Answer #2 (Rav): One may move them only within four Amos.

(R. Yosah bei R. Bun): Rav taught like he taught elsewhere, and R. Yochanan taught like he taught elsewhere;

R. Yochanan taught that a Korah (a horizontal beam over the opening of a Mavuy) permits without Shituf. He taught that we may move them in the entire Mavuy;

Rav taught that a Korah does not permit without Shituf. He said that we may move them only within four Amos.

Question: According to R. Yochanan, why do we make Shituf in the entire Mavuy?

Answer (R. Yosah bei R. Bun): It is in order to make all the Reshuyos one (permit transferring even from houses to the Mavuy and vice-versa).

(R. Simon citing R. Yehoshua ben Levi): A Milah knife - he makes Cholah (rows of people; they are considered Mechitzos), and brings it [between them].

A case occurred with Bar Marinah. He asked R. Simon, and he permitted him. He asked R. Ami, and he forbade. R. Simon was upset.

Question: Was it not taught that if one asked a Chacham, and he permitted, one may ask another Chacham, perhaps he will forbid?! (Why was R. Simon upset?)

Answer (R. Yudan): The case is, [Bar Marinah] asked R. Ami, and he forbade. He asked R. Simon, and he permitted. R. Ami was upset;

This is like it was taught, that if one asked a Chacham, and he forbade, he may not ask another Chacham, perhaps he will permit.

In the days of R. Yirmeyah, they forgot [to bring before Shabbos] the keys to the Beis Midrash. They asked him. He said, when you see many people, bring them through Cholah.

Source: R. Yirmeyah learns from [a Beraisa]. Any Cholah, whether they knew [that they are making a wall] or did not know, it is a Cholah (Mechitzah).

R. Yudah bar Pazi ruled to bring them via shoes. (It is not normal to carry like this.)

R. Chinena bar Papa ruled to bring them through a Cholah, via shoes. (He required two deviations from a Torah Isur - MEROMEI SADEH.)

A case occurred in which R. Shmuel bar Rav Avdomi needed to circumcise his son Rav Shisha [on Shabbos]. They forgot to bring the knife.

He asked R. Mana; he told him to postpone it until tomorrow. He asked R. Yitzchak bar Elazar. He told them "to grind the spices into the wine, you did not forget. To bring the knife, you forgot!?'' Postpone it until tomorrow.

Support (R. Yosi bei R. Bun citing R. Chunah): [They must postpone it, for] our Mishnah forbids making a Cholah!

(Mishnah - R. Eliezer): If one did not bring the Kli (knife) on Erev Shabbos, one brings it openly on Shabbos.

If you will say so, that it is permitted [to make a Cholah, why does R. Eliezer permit a Melachah mid'Oraisa?!] Can he not find [people] to make a Cholah, and bring it?!
