SHABBOS 102 - Two weeks of study material have been dedicated by Mrs. Estanne Abraham Fawer to honor the thirteenth Yahrzeit of her father, Rav Mordechai ben Eliezer Zvi (Rabbi Morton Weiner) Z'L, who passed away on 18 Teves 5760. May the merit of supporting and advancing Dafyomi study -- which was so important to him -- during the weeks of his Yahrzeit serve as an Iluy for his Neshamah.
(a) What does our Mishnah rule in a case where, after throwing a stone be'Shogeg on Shabbos ...
1. ... from one Reshus to another, somebody else or a dog caught it, or it got burned, before landing?
2. ... with the intention of wounding somebody or an animal, he remembered that it was Shabbos, before it hit the person or the animal?
(b) According to the principle cited by the Tana regarding an act for which one is Chayav Chatas be'Shogeg, what will be the Din if only the beginning is performed be'Meizid, or only the end is performed b'Meizid?
(c) When is one then Chayav Chatas?
(d) What is the problem with the Reisha ('ha'Zorek ve'Nizkar ... Kaltah Acher ... Patur'), which we initially assume to be one case?
(a) The Reisha of the Mishnah implies that if , after throwing the object and remembering that it is Shabbos, it falls to the ground, he is Chayav. How does this clash with the Seifa 'Zeh ha'K'lal, Kol Chayvei Chata'os, Einan Chayavin ad she'Tehei Techilasan ve'Sofan Shegagah'?
(b) To resolve this discrepancy, Rav Kahana establishes the Seifa by 'Lachsa u'Misna'. What does this mean?
(c) How does it answer the Kashya? What makes this more Meizid than the original case?
(d) We reject this solution however, on the basis of 'Ogdo be'Yado'. What does this mean?
(a) We suggest that the Tana is talking where he intented, not to throw the stone, but to wound someone with it. How does that answer the Kashya of 'Ogdo be'Yado'?
(b) On what grounds do we reject the answer that the Reisha is talking when ...
1. ... he intended to make a wound (and not just to throw the stone)?
2. ... he intended to carry the stone four Amos in the street, and not to throw it (Rava)?
(c) Rava finally answers 'Tarti Katani'. What does he mean? How does this answer the question?
(d) Rav Ashi answers 'Chasuri Mechsera ... '. What does he add to the Reisha (after 'Kaltah Kelev ... Patur'), to reconcile it with the Seifa?
(a) Rabah and Rava argue over someone who carries two Amos be'Shogeg, two Amos be'Meizid ( ... he remembers that it is Shabbos) and another two Amos be'Shogeg. Both refer to the Machlokes Raban Gamliel and the Rabbanan. Raban Gamliel holds 'Ein Yedi'ah le'Chatzi Shi'ur'. What does this mean?
(b) Rabah holds in the current She'eilah that he is Patur. What does Rava say?
(c) Why, according to ...
1. ... Rabah, will even Rabban Gamliel concede that he is Patur from a Korban?
2. ... Rava, will even the Rabbanan concede that is Chayav a Korban?
(d) How do we know that ...
1. ... Rava is speaking about throwing and not carrying?
2. ... Rabah is speaking about carrying and not throwing?
(a) What is the problem with Rava's ruling, that if someone throws an object into the mouth of a dog or a furnace, he is Chayav?
(b) How do we reconcile Rava with our Mishnah?
(a) Rav Bibi bar Abaye supports this with a Mishnah in Kerisus. What does the Tana Kama there say about a Tamei person who ate Cheilev of Nosar of Mukdashin on Yom Kippur? How many Chata'os is he Chayav besides the one Asham?
(b) On what grounds does the Tana Kama disagree with Rebbi Meir, who adds a Chatas in a case where it was also Shabbos?
(c) What is the problem with the last case?
(d) What do we answer? What proof does Rav Bibi bar Abaye now bring from there?
Hadran Alach 'ha'Zorek'
(a) What is the Shi'ur for Binyan, Mesates, Makeh be'Patish (u've'Ma'atzad) and Kode'ach?
(b) 'Mesates' means smoothening the stones after they have been shaped, or cutting grooves in it. What is the definition of ...
1. ... 'Makeh be'Patish'?
2. ... a 'Ma'atzad'?
3. ... 'Kode'ach'?
(c) What principle does the Mishnah present to define a Melachah for which one is Chayav on Shabbos?
(d) Rabban Shimon ben Gamliel adds, that a worker who bangs his hammer on the anvil whilst working, is also Chayav because of Makeh be'Patish. What is he coming to teach us?
(a) Rebbi Yirmiyah initially defines a Binyan Kol she'Hu as a poor man who digs a hole to hide his Perutos. What was the source of this in connection with the construction of the Mishkan?
(b) What practical objection does Abaye raise to this explanation?
(c) He therefore defines it as the small metal legs that a poor man would make for his earthenware oven. What equivalent Melachah was performed in the Mishkan?
(d) What objection does Rav Acha bar Ya'akov objects to Abaye's explanation?
(e) Rav Acha bar Ya'akov finally explains the Shi'ur of Kol she'Hu with regard to a hole that appears in a mansion, which a wealthy man would make a point of filling in. What similar Melachah was performed in the Mishkan?
(a) Shmuel rules 'ha'Metzaded es ha'Even, Chayav'. What is 'Metzaded'?
(b) We query Shmuel from a Beraisa, which discusses a case where one person places the brick, and another cements it. What does the Tana Kama say? Why does this pose a Kashya on Shmuel?
(c) We counter this with the Seifa. What ruling does the Seifa issue that is even more stringent than that of Shmuel?
(d) We therefore conclude that there are actually three cases, each with its own Din. Under which circumstances will one be Chayav for placing a brick in the ...
1. ... bottom row?
2. ... middle row?
3. ... top row?
(a) Rav holds that Mesates, someone who makes a hole in a chicken-coop or who places a wedge in the handle of a spade, are all Chayav because of Boneh. What is the purpose of the hole in the chicken-coop?
(b) What does Shmuel hold in all of these cases?
(c) Having presented their Machlokes by ...
1. ... Mesates, why did they need to add the case of making a hole in a chicken-coop? Why might Rav have rules differently there?
2. ... making a hole in a chicken-coop, why did they need repeat it by the case of a wedge in the handle of a spade? Why might Rav have ruled differently there?
(a) When Rav Nasan bar Oshaya asked Rebbi Yochanan with which Melachah Mesates is associated, what did he illustrate with his hand?
(b) How does he (and Shmuel) then explain our Mishnah, which writes 've'ha'Mesates, ve'ha'Makeh be'Patish' ... Chayav?
