Rosh Kollel: Rabbi Mordecai Kornfeld
(a) So Rava establishes the case of Shogeg be'Lo Miskaven (not be Avodah-Zarah, but) by other sins, specifically those that entail physical pleasure (such as eating Cheilev). What will then be the case? Why is that?
(b) What is the equivalent case by Shabbos (for which he is only Chayav one Chatas)? How does Rava attempt to prove his opinion from here?
(c) Abaye establishes the case by someone who swallows melted Cheilev, thinking it is spittle. What is the equivalent case by Shabbos (which effectively counters Rava's proof)?
(a) If someone intends to throw an object two Amos, and he throws it four, Abaye rules that he is Chayav (since he intended to perform the basic act of throwing). On what grounds does Rava exempt him from a Chatas?
(b) We have already discussed Abaye and Rava's Machlokes regarding someone who intends to cut what is detached, but inadvertently cuts what is attached. In a third Machlokes, regarding someone who throws four Amos in a location which he believes to be a Reshus ha'Yachid, but it turns out to be a Reshus ha'Rabim, Rava again says that he is Patur. Having issued his ruling in the case of ...
1. ... cutting, why did Rava find it necessary to add the case where he intended to throw less than four Amos ... ?
2. ... where he intended to throw less than four Amos ..., why did he need to add the case where he throws four Amos in a location which he believes to be a Reshus ha'Yachid, but it turns out to be a Reshus ha'Rabim?
(a) We have already quoted the forthcoming Mishnah 'Avos Melachos, Arba'im Chaser Achas', and established the Chidush to be that even if someone transgressed all the Melachos (be'Shigegas Melachos) in one He'elam, he is Chayav thirty-nine Chata'os. According to Abaye, Zadon Shabbos, in the Mishnah of 'Avos Melachos Arba'im Chaser Achas', speaks when he knew about all the Melachos of Shabbos, but did not know their Shiurim; According to Rebbi Yochanan, it speaks when he knew about the Isur La'av, but not about the Chiyuv Kares. What problem do we have in establishing the Mishnah according to Rava?
(b) Assuming that Rava rules that 'Heizid be'Kareis ve'Shagag be'La'av' is Chayav (like Rebbi Yochanan), that is how he will explain the Mishnah. But how will he explain it if he holds Patur (like Resh Lakish)?
(c) Like which Tana will he then hold?
(a) In what connection were the following Melachos performed in the construction of the Mishkan ...
1. ... The first group comprising eleven Melachos (from sowing through to baking)?
2. ... The second group comprising five Melachos (from shearing wool through to spinning)?
3. ... The third group comprising eight Melachos (from stretching the threads of the warp through to tearing)?
4. ... The fourth group comprising seven Melachos (from trapping deer through to cutting the skin to size)?
(a) What do the Melachos of tearing and erasing have in common?
(b) Why will the Melachah of demolishing also belong in this group?
(c) What do the following seven Melachos have in common: placing threads into the loops for weaving, weaving, splitting threads, stitching, tearing, writing and erasing?
(d) What is the definition of the Melachah of Makeh ba'Patish? Why is it called by this name?
(a) Since one normally plows before sowing, why does our Tana put sowing first?
(b) What do sowing, pruning, planting, replanting an attached branch and grafting all have in common? What are the ramifications of this statement?
(c) Which one of these is in fact, a Toldah?
(d) What Chidush is Rebbi Ami coming to tell us when he says that planting, replanting and grafting are Chayav because of sowing?
(a) When will one be Chayav two Chata'os for pruning?
(b) What is Aspasta, and how many Chata'os will one have to bring for cutting it from the ground?
(c) How many Chata'os will one have to bring for cutting a beet from its stalk?
(a) How many Chata'os will someone who plows, digs a hole and digs ditches in the ground in one He'elam be Chayav to bring?
(b) Which Av Melachah will one have contravened for removing a mound of earth, or by filling in a hole ...
1. ... in the house?
2. ... in the field?
(c) When is one Chayav for digging a hole and when is one Patur (according to Rebbi Shimon)?
(d) When will he be Patur - even according to Rebbi Yehudah?
(a) Kotzer, Botzer, Goder, Mosek, and Orah are all are all words that mean harvesting or picking. With re. to which kind of fruit would one use these different terms?
(b) According to Rav Papa, someone who throws a clod of earth at a date-palm on Shabbos, and detaches dates, has transgressed two Melachos. Which ones?
(c) On what grounds does Rav Ashi disagree with him? How many Melachos does one transgress, according to him?
(d) Rabah maintains that someone who gathers salt next to a salt-mine has transgressed the Melachah of Me'amer. What does Abaye say about that?
(a) Dash, Menapetz and Menapet are one and the same Melachah. What do they mean?
(b) Why is Menapetz of flax a Toldah of Dash and not a Toldah of Menapetz of wool?
