(a)By the same token (as the water-pit and the house), Reish Lakish Amar Rebbi Yanai states that if Reuven sells Shimon a flock of sheep, Shimon acquires it (i.e. can acquire it without the invitation of 'Lech Chazek u'Keni!') as soon as Reuven hands him the Mashchuchis (something with which one draws the entire flock, and which will be explained shortly). Here too, we ask whether he is acquiring the flock with Meshichah or with Mesirah. What is the difference between Meshichah and Mesirah?

(b)Under which circumstances will Mesirah be necessary?

2)

(a)Some say that 'Mashchuchis' is a Karkashta. What is 'a Karkashta'?

(b)How does Rebbi Yakov interpret 'Mashchuchis'?

(c)We substantiate Rebbi Yakov's interpretaion of Mashchuchis with a saying of a certain Galilean 'above' Rav Chisda. What did that Galilean say about a shepherd who is angry with his flock?

3)

(a)Under which circumstances does our Mishnah obligate Shimon and not Reuven, for using the water-pit?

(b)We will learn later that if a normal ox falls into an open pit, the owner of the pit is Patur (because a healthy animal is expected to look where it is going). In which case does our Mishnah nevertheless declare the owner of the pit Chayav?

(c)Why is the owner of the pit Chayav and not the worker who caused the ox to fall?

(d)What if the noise of the digging caused the ox to fall backwards into the pit?

4)

(a)What does our Mishnah say in a case where an ox or a donkey falls into a pit together with its accessories, and those of the ox break or those of the donkey tear?

(b)Why does the Tana change from 'break' by the ox to 'tear' by the donkey?

(c)And what he say with regard to ...

1. ... a 'Shor Chashu' that fell into a pit?

2. ... a child, an Eved or Shifchah who fell into a pit?

(d)Why does the Tana mention a child rather than just a person?

5)

(a)We learned in our Mishnah that if Reuven covered the water-pit after use, Shimon and not Reuven, is subsequently liable once he uses it. According to Rav, Reuven is only Patur until such time as he sees for himself that the pit is uncovered. What does Shmuel say?

(b)Some interpret Shmuel as being more lenient than Rav. What do they mean?

6)

(a)Our Mishnah ruled that if the owner covered his pit properly and an ox or a donkey fell in, he is Patur. If he covered it properly, how does Rebbi Yitzchak bar bar Chanah explain the fact that the animal managed to fall into the pit?

(b)We ask what the Din will be if the owner covered the pit properly against oxen falling in, but not against camels. What is the case? What exactly happened?

(c)We query this inasmuch as if passing camels are common, then he was careless (and is obviously Chayav), whereas if they are not, then he is an Ones (and is Patur). How do we therefore establish the case?

7)

(a)We try and resolve the She'eilah (that ka'Ra'uy for oxen but not for camels and a camel weakened the cover ... is Patur) from our Mishnah 'Kisahu v'Nafal Shamah Shor O Chamor, u'Mes, Patur'. What does that prove?

(b)We counter the proof by establishing our Mishnah like Rebbi Yitzchak bar bar Chanah? What does Rebbi Yitzchak bar bar Chanah say?

52b----------------------------------------52b

8)

(a)We then try and prove that the owner is Chayav in the case currently under discussion, from the Seifa of our Mishnah 'Lo Kisahu ka'Ra'uy', v'Nafal l'Tochao Shor O Chamor, u'Mes Chayav'. Using the same argumets as we just used to explain the Reisha of the Mishnah, how do we establish 'Lo Kisahu ka'Ra'uy'?

(b)We counter this too, by establishing 'Lo Kisahu ka'Ra'uy' to mean that it was not properly guarded, either against camels falling in or against oxen. Then what is the Chidush of the Seifa?

(c)According to the second Lashon, the case where the pit is guarded against oxen but not against camels that passed from time to time does not even come into question. Why not? What do we now hold in that case?

(d)The new format of the She'eilah is that, although the pit was guarded against oxen falling in but not against camels, in fact, neither transpired. What did happen? What are now the two sides of the She'eilah?

9)

(a)We try to resolve the She'eilah from Rebbi Yitzchak bar bar Chanah (who establishes our Mishnah ['Kisahu ka'Ra'uy ... Patur'] when the cover became wormy). How do we try and prove our point from there?

(b)We counter this proof however, by establishing our Mishnah when in fact, the cover was strong enough to guard the pit against both oxen and camels from falling in. Then what is the Chidush? What could the owner have done?

(c)We then try to resolve the She'eilah from the Seifa 'Lo Kisahu ka'Ra'uy ... Chayav', which must speak when the cover was Ra'uy for oxen but not for camels, but in the end, the cover became wormy, to teach us that we say 'Migo' (otherwise there would be no Chidush). How do we counter this proof? How else might the Tana be speaking?

10)

(a)We finally resolves the She'eilah from a Beraisa. What does the Tana there say about ...

1. ... a Chashu ox, one that is blind or one that is healthy that falls into a pit during the night?

2. ... a healthy ox that falls into a pit during the day?

(b)What does this prove?
