Question: Why is it clearly not permitted to immerse a Kli on Shabbos?

Answer (Rabah): It is a Gezeirah lest one carry the Kli to or from the Mikveh.

Question (Abaye): What would then be the Halachah if one had a Mikveh on his property?

Answer: We would prohibit that lest we come to permit the Mikveh outside his property.

Question: What about on Yom Tov (where in this case there is no Isur Hotza'ah)?

Answer: We prohibit on Yom Tov lest he permit it on Shabbos.

Question: But the Mishnah does not apply that reasoning (which would cause us to prohibit Hashakah lest we come to permit Tevilah)!?

Answer: The situation is obviously one in which he has no other water, and the care which he will naturally exercise precludes the need for a Gezeirah there.

Question: Then how could the Beraisa permit drawing water with a Kli Tamei (lest he come to immerse the Kli itself without drawing with it)!?

Answer: The fact that he is only permitted to lower the Kli in order to draw with it serves as a reminder that he may not immerse it directly (or carry it).

Question: How could the Beraisa permit the immersion of a Kli which became Tamei on Yom Tov, lest he come to immerse a Kli which became Tamei before Yom Tov!?

Answer: Tum'ah on Yom Tov is unlikely (given the Taharah preparations before Yom Tov) and thus not subject to a Gezeirah.

Question: Again, we should apply the Gezeirah reasoning to prohibit immersing a Kli which was exposed to a Vlad ha'Tum'ah (which is Tum'ah d'Rabanan in Kelim) lest we immerse one exposed to an Av ha'Tum'ah!?

Answer: Such a Kli is only relevant to Kohanim, who are Zerizim.

Question: We should prohibit a woman from immersing with her clothing lest she immerse the clothing separately!?

Answer: The fact that she is only permitted to immerse with her clothing will serve as a reminder (not to carry the items to the Mikveh).

Answer (R. Yosef): It is a Gezeirah lest one come to Sechitah.

Question (Abaye): What about non-squeezable Kelim?

Answer (R. Yosef): Gezeirah.

Question: All the above questions.

Answer: All the above answers.

Answer (R. Bibi): It is a Gezeirah lest one leave his Kelim for Tevilah on Yom Tov (supported by a Beraisa).

Answer (Rava): Tevilah is prohibited since it appears like Mesaken Kli.

Question: Then the same should apply to a person!?

Answer: A person gives the appearance of going into the water to cool off.

Question: But what if the water is turbid?

Answer (R. Nachman b. Yitzchak): On a hot day someone might use even this water.

Question: What about when he is not so hot, as in the rainy season?

Answer (R. Nachman b. Yitzchak): A person who is soiled might rinse off even during the rainy season.

Question: How could it be permitted on Yom Kipur?

Answer (Rava): Whatever (Ho'il) is permitted on Shabbos is permitted on Yom Kipur.

Question: But we find that Rava does not subscribe to Ho'il (since he gave a different answer to resolve the contradictory Beraisos dealing with eating and Refuah)?

Answer: Rava reversed his position in that discussion, and applied Ho'il.

Question: How do we know that he reversed his position there in favor of Ho'il; perhaps he reversed his position here against Ho'il?!

Answer: That seems unlikely given the Beraisa which permits Tevilah on Yom Kipur (which must be on account of Ho'il).

Question: What is meant by not doing Tevilah?

Answer (Shmuel): It prohibits doing Hashakah with the water within a Kli in order to be Metaher the Kli as well.

Question: Who is the author of our Mishnah?

(Rebbi): One may not do Tevilah or Hashakah.

(Rabanan): One may do either.

According to Rebbi, Hashakah is not permitted, yet our Mishnah permits it.

According to Rabanan, Tevilah is permitted and our Mishnah forbids it!?

Answer: Our Mishnah could be either Rebbi or Rabanan.

If Rebbi, we will assume that he forbids Tevilah on Yom Tov (when only Hashakah is permitted) and prohibits Hashakah (the second part of his statement in the Beraisa) on Shabbos (while our Mishnah is speaking entirely about Yom Tov).

If Rabanan, they permit both on Yom Tov and our Mishnah would be speaking entirely about Shabbos.
