 Previous SHABBOS 8 Next Ask theKollel

1)

(a) According to Abaye, if someone throws a Kaveres (a bee-hive) which is ten Tefachim tall and six Tefachim in diameter, he is Patur; whereas if the diameter is less than six Tefachim, he is Chayav. Why is that?

(b) In fact, when Abaye says Chayav, this is not always the case. What would he hold by a Kaveres that is between five and three fifths and six Tefachim, and what does he mean when he says 'Chayav'?

(c) Why does Rava exempt him from a Chiyuv, even if the Keveres is less than six Tefachim?

2)

(a) If the Kaveres (of less than six Tefachim in diameter) landed upside down, he is Patur, provided it is at least seven and a half Tefachim tall or more. Why is that?

(b) Must the Kaveres be specifically seven and a half Tefachim?

(c) Rav Ashi says that he is Chayav even in this case. Why is that?

3)

(a) If someone throws four Amos on to a board which is fixed in the Reshus ha'Rabim at a height of between three and nine Tefachim, will he be Chayav?

(b) What will be the Din if it lands on a board which is nine Tefachim from the ground, and why the difference?

(c) Rav Yosef says that the same applies to a hole of nine Tefachim deep. What does Rava say about that?

(d) According to Rav Yosef, what does the Beraisa mean when it says 've'Chen be'Guma'?

8b----------------------------------------8b

(a) 'Niskaven Lishbos bi'Reshus ha'Rabim, ve'Hini'ach Eiruvo ba'Bor le'Ma'alah mi'Yud Tefachim, Eiruvo Eiruv, le'Matah mi'Yud Tefachim, Ein Eiruvo Eiruv'. How do we explain 'le'Ma'aleh mi'Yud' ... Eiruvo Eiruv'?

(b) What is then the Kashya on Rava (in 3c.)

(c) The Gemara answers that the Beraisa speaks when he and his Eiruv are in a Karmelis. What does this mean, and why does it then refer to it as a Reshus ha'Rabim?

(d) In the second answer, we establish the Beraisa like Rebbi. What is the Gemara's second answer?

5)

(a) The Mishnah in ha'Zorek says 'Im Hayah Rekek Mayim, u'Reshus ha'Rabim Mehaleches Bo, ha'Zorek le'Sochah Arba Amos, Chayav.... ve'Rekek Mayim she'Reshus ha'Rabim Mehaleches Bo, ha'Zorek le'Socho Arba Amos, Chayav'. Why does the Tana see fit to mention 'Rekek Mayim' twice? Why are they both necessary?

(b) And how do we prove Rava's opinion ('Tashmish Al Yedei ha'Dechak, Lo Shemei Tashmish') from the Tana's repetition of the word 'Mehaleches Bo'?

6)

(a) One might transport a large bundle of long canes by picking up one end and letting it fall along the street. Would he then be Chayav for carrying on Shabbos, and why is that?

7)

(a) We learnt above (in 6a.) in a Beraisa, that one may stand on a threshold and take from a poor man or give to him. Which kind of threshold must this be speaking about?

(b) What exactly is the threshold of a Reshus ha'Rabim?

(c) The threshold of a Karmelis is one that is between the heights of three and ten Tefachim. What, in this context, are the three thresholds of a Reshus ha'Yachid ?

(d) The Beraisa exempts someone who is standing on a Makom Petur, and who takes an article from someone in one Reshus, and hands it to someone in the opposite Reshus. In that case, how do we explain Rava, who rules that someone who carries an article above ten Tefachim (which is a Makom Petur) is Chayav?
