Shabbos 42


(a) Why is it permitted to extinguish a hot piece of metal lying in the street, but not a burning wooden faggot?

(b) The Gemara asks that, since Shmuel holds like Rebbi Shimon by a Davar she'Ein Miskaven, why is he not lenient here too, like Rebbi Shimon. What is the Gemara actually asking?

(c) What does the Gemara answer?

(a) What would one do with dangerous thorns ---
1. ... in the Reshus ha'Rabim?
2. ... in a Karmelis?
(b) Why the difference?
(a) Why do Beis Shamai permit the pouring of hot water into cold, but not vice-versa?

(b) Why do Beis Hillel permit even cold water into hot - when it is in a cup?

(a) Rav Yosef maintains 'Sefel, Harei Hu ke'Ambati'.
On what grounds does Abaye disagree with this statement?

(b) The Beraisa concludes 've'Rebbi Shimon ben Menasyah Oser', and Rav Nachman rules like him.
What problem does that create with Rav Yosef's ruling?

(c) How does the Gemara nevertheless explain Rebbi Shimon ben Menasyah according to Rav Yosef?

(d) Does that mean that Rebbi Shimon ben Menasya holds like Beis Shamai?

(a) How do we initially explain Rebbi Chiya's Beraisa 'Nosen Adam Kiton shel Mayim le'Toch Sefel Shel Mayim, Bein Chamin le'Toch Tzonan, Bein Tzonan le'Toch Chamin'?

(b) Why could Rava not have learnt from there the concession of pouring even cold water into hot water?

(c) How do we amend the Beraisa, for Rava's proof from the Beraisa to be correct?

Answers to questions



(a) Why is it forbidden to add spices to a boiling pot even after it has been removed from the stove?

(b) Why is it permitted to add spices to a *dish* or *plate* containing hot food?

(c) Rebbi Yehudah says 'le'Kol Hu Nosen, Chutz mi'Davar She'Yesh bo Chometz ve'Tzir'.
What makes Chometz and Tzir different than other hot dishes?

(a) 'Rebbi Yehudah Omer, la'Kol Hu Nosen - Chutz mi'Davar she'Yesh Bo Chometz ve'Tzir'.
What is Rebbi Yehudah talking about, and how might he be either more lenient or more strict, than the Tana Kama?

(b) What does the Gemara conclude? Is he more lenient that the Tana Kama or is he stricter than him?

(a) Rav Yosef thought that salt has the same Din as spices when it comes to putting it into a hot K'li Rishon or K'li Sheni. Abaye, again quoting a Beraisa of Rebbi Chiya, points out that salt is *not* like spices. But there are two versions of what the Beraisa said.
What are the two versions?

(b) One of the versions concurs with Rav Nachman's statement 'Tzericha Milcha Bishula ke'Bisra de'Tura'; the other version disagrees.
What does Rav Nachman mean?

(a) When does the Tana of our Mishnah permit one to place a receptacle underneath a lamp, to receive the oil which drips on Shabbos?

(b) Does this mean that the oil is then permitted?

(c) Rav Chisda learns from our Mishnah, that one may not place a receptacle under a chicken which is laying an egg on a slope, but that one *is* permitted to place it over an egg in a trash-heap to prevent it from being trodden on and broken.
How does Rabbah explain Rav Chisda's reasoning?

10) How does Rabbah explain the Mishnah (or the Beraisa), which permits placing ...
1. ... a receptacle underneath a broken barrel of Tevel wine, from which wine is dripping?
2. ... a receptacle underneath a lamp to catch the falling sparks?
3. ... a dish over a lamp to prevent the beam from burning?
4. ... a bench to support a broken beam which broke?
