Ask A Question on the daf

Previous daf

Beitzah 18


(a) Question: Why is it clearly not permitted to immerse a Keli on Shabbos?
(b) Answer (Rabah): It is a Gezeirah lest one carry the Keli to or from the Mikveh.
1. Question (Abaye): What would then be the Halachah is one had a Mikveh on his property?
2. Answer: We would prohibit that lest we come to permit the Mikveh outside his property.
3. Question: What about on YomTov (without the Isur Hotza'ah)?
4. Answer: We prohibit on YomTov lest he permit it on Shabbos.
5. Question: But the Mishnah does not apply that reasoning (which would cause us to prohibit Hashakah lest we come to permit Tevilah)!?
6. 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.
7. Question: Then how could the Beraisa permit drawing water with a Keli Tamei (lest he come to immerse the Keli itself without drawing with it)!?
8. Answer: The fact that he is only permitted to lower the Keli in order to draw with it serves as a reminder that he may not immerse it directly (or carry it).
9. Question: How could the Beraisa permit the immersion of a Keli which became Tamei on YomTov, lest he come to immerse a Keli which became Tamei before YomTov!?
10. Answer: Tumah on YomTov is unlikely (given the Taharah preparations before YomTov) and thus not subject to a Gezeirah.
11. Question: Again, we should apply the Gezeirah reasoning to prohibit immersing a Keli which was exposed to a Vlad HaTumah (which is Tumah d'Rabanan in Keilim) lest we immerse one exposed to an Av HaTumah!?
12. Answer: Such a Keli is only relevant to Kohanim, who are Zerizim.
13. Question: We should prohibit a woman from immersing with her clothing lest she immerse the clothing separately!?
14. 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).
(c) Answer (R. Yosef): It is a Gezeirah lest one come to Sechitah.
1. Question (Abaye): What about non-squeezable Kelim?
2. Answer (R. Yosef): Gezeirah.
3. Question: All the above questions.
4. Answer: All the above answers.
(d) Answer (R. Bibi): It is a Gezeirah lest one leave his Kelim for Tevilah on YomTov (supported by a Beraisa). (e) Answer (Rava): Tevilah is prohibited since it appears like Mesaken Keli.
1. Question: Then the same should apply to a person!?
2. Answer: A person gives the appearance of going into the water to cool off.
3. Question: But what if the water is turbid?

4. Answer (R. Nachman b. Yitzhok): A tired person might use even this water.
5. Question: What about when he is not so hot, as in the rainy season?
6. Answer (R. Nachman b. Yitzhok): A person who is soiled might rinse off even during the rainy season.
7. Question: How could it be permitted on Yom Kipur?
8. Answer (Rava): Whatever (Ho'il) is permitted on Shabbos is permitted on Yom Kipur.
i. 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)?
ii. Answer: Rava reversed his position in that discussion, and applied Ho'il.
iii. 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?!
iv. Answer: That seems unlikely given the Beraisa which permits Tevilah on Yom Kipur (which must be on account of Ho'il).
(a) Question: What is meant by not doing Tevilah?
(b) Answer (Shmuel): It prohibits doing Hashakah with the water within a Keli in order to be Metaher the Keli as well.
(c) Question: Who is the author of our Mishnah?
1. (Rebbi) One may not do Tevilah or Hashakah.
2. (Rabanan) One may do either.
3. According to Rebbi, Hashakah is not permitted, yet our Mishnah permits it.
4. According to Rabanan, Tevilah is permitted and our Mishnah forbids it!?
(d) Answer: Our Mishnah could be either Rebbi or Rabanan.
1. If Rebbi, we will assume that he forbids Tevilah on YomTov (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 YomTov).
2. If Rabanan, they permit both on YomTov and our Mishnah would be speaking entirely about Shabbos.
