BAVA BASRA 80 (10 Elul 5784) - This Daf has been dedicated in memory of Sheina Basha (daughter of Yakov and Dora) Zuckerman, who passed away on 10 Elul, by her children and sons in law.

1)

(a)

Our Mishnah now discusses the sale of a dove-cote. What is a 'B'reichah' (in this connection)?

(b)

What is the birth-rate of doves?

(c)

What does the Tana say about someone who purchases one year's fruit of his dove-cote?

(d)

Why is that?

2)

(a)

What is a 'N'chil shel Devorim'?

(b)

What does our Mishnah say about someone who sells one year's fruit of his bee-hive'?

(c)

How often does a swarm of bees appear in the course of a year?

(d)

From then on, the seller may perform Sirus on his remaining bees. What is 'Sirus'?

(e)

Why does one do it?

3)

(a)

What are 'Chalos D'vash'? What do they consist of?

(b)

How many honey-combs is one likely to find in a bee-hive?

(c)

What is the purpose of the two honey-combs that the purchaser leaves the owner, if he purchased one year's fruit of the bee-hive?

(d)

What does our Mishnah obligate Shimon to leave for Reuven, should he purchase the branches of his olive-tree?

4)

(a)

We query our Mishnah, which requires the purchaser of the fruit of a dove-cote to leave one brood of doves for the owner, from a Beraisa. What does the Beraisa say?

(b)

How does Rav Kahana interpret 'B'reichah Sheni'ah' of the Beraisa, to resolve the discrepancy? Why does the Tana refer to it as B'reichah Sheni'ah (and not Rishonah)?

(c)

Why is it necessary to leave over another brood as company for the first one? Why will the company of their mother not suffice (like their mother requires only them)?

(d)

And why will its sibling not suffice as company? Why does it need its off-spring?

5)

(a)

How does Rav Yehudah Amar Shmuel explain Mesarsan' (stopping the bees from reproducing)? What does the owner do to achieve this?

(b)

Do the mustard-seeds really stop the bees from reproducing? How do they quote Rebbi Yossi b'Rebbi Chanina who explains it?

(c)

Rabeinu Chananel explains Rebbi Yossi b'Rebbi Chanina differently. How does he explain his words?

(d)

Why is that?

6)

(a)

Rebbi Yochanan interprets 'Mesarsan' quite differently. What does it mean according to him?

(b)

Rebbi Yochanan however, appears to have ignored the 'Vav' in 'u'Mesarsan' in our Mishnah. The Halachah therefore, is like the Beraisa, which takes it into account. What does the Beraisa say?

7)

(a)

Rav Kahana rules that honey in the beehive never loses its status as a food. What are the ramifications of this ruling?

(b)

Assuming that Rav Kahana means that even when the bees are eating the honey (as we just learned), the honey retains its status as a food, until when will this ruling apply?

(c)

Alternatively, he means that only as long as the honey is in the beehive, it has the status of a food. What status will the honey have once it flows from the hive?

(d)

In what way does the Din of a beverage differ from that of a food?

(e)

We query Rav Kahana's initial statement from a Beraisa. What does the Tana there say about honey in a beehive?

80b----------------------------------------80b

8)

(a)

To resolve the Kashya, how does Abaye establish the Beraisa?

(b)

Rava disagrees with Abaye's answer. He establishes the author of the Beraisa as Rebbi Eliezer. What does Rebbi Eliezer say in the Mishnah in Shevi'is, about a beehive and its contents which will explain why the honey inside it is not considered food?

(c)

What does Rav Kahana say to that?

(d)

Rebbi Elazar cites Rebbi Eliezer's source as the Pasuk in Shmuel (in connection with Yonasan ben Shaul) "va'Yitbol osah be'Ya'aros ha'Devash". What does Rebbi Eliezer learn from there?

9)

(a)

The Beraisa states that once honey has flowed from a beehive, it is neither a food nor a beverage. Why is this ...

1.

... not a Kashya on Abaye (in Rav Kahana)?

2.

... a Kashya on Rava (in Rav Kahana)? Why can Rava not simply establish the author as Rebbi Eliezer?

(b)

To answer the Kashya on Rava, Rav Z'vid establishes the Beraisa where the honey flowed straight on to a dirty vessel. How does that answer the Kashya?

(c)

Why must the author then be Rebbi Eliezer)? With which point will the Rabbanan disagree?

(d)

Rav Acha bar Ya'akov establishes the Beraisa where the honey flowed on to little splinters of wood. What will he hold in a case where it flowed on to dirty vessels?

10)

(a)

Another Beraisa considers honey in the beehive neither a food nor a beverage unless one has specifically in mind either the one or the other. How will Abaye establish the Beraisa?

(b)

How does this Beraisa pose a Kashya on Rava?

(c)

We answer this by establishing the Beraisa like Rebbi Eliezer. How do we then amend the Beraisa (see Tosfos)?

(d)

We finally cite a Beraisa in support of Rav Kahana. What does the Beraisa say about honey in a beehive?

11)

(a)

The Beraisa now discusses the sale of a tree. If someone purchases a tree to cut down and take away, for it to re-grow, he must leave one Tefach of the trunk standing, with some exceptions. How much is he obligated to leave of a ...

1.

... a Besulas ha'Shikmah (a wild fig-tree that is being cut down for the first time)?

2.

... a Sadan ha'Shikmah (one that has been cut down before and has re-grown)?

3.

... bamboo-trees and vines?

(b)

Why may date-palms and cedars-trees be taken out together with the roots?

(c)

On what grounds does the Beraisa forbid cutting down a 'Besulas ha'Shikmah in the Sh'mitah-year?

(d)

Rebbi Yehudah forbids cutting it down in the normal way, only above ten Tefachim or down to the ground. Why is that?

12)

(a)

What can we extrapolate from Rebbi Yehudah that creates an apparent discrepancy between this Beraisa and the previous one?

(b)

To resolve the discrepancy, how does Abaye differentiate between cutting a Besulas ha'Shikmah down to the ground and from there up to three Tefachim?

(c)

How does this answer the Kashya? What is the difference between Shevi'is and a purchaser in this regard?

13)

(a)

Rebbi Chiya bar Luli'ani Darshens the Pasuk' 'in Tehilim "Tzadik ka'Tamar Yifrach, ke'Erez ba'Levanon Yisgeh". Having written ...

1.

... 'Tamar', why does the Pasuk find it necessary to write 'Erez'?

2.

... 'Erez', why does the Pasuk need to write 'Tamar'?

(b)

How do we reconcile this with the above Beraisa, that a purchaser is permitted to pull palms and cedars out by the roots - because they will not re-grow anyway?

(c)

What do an oak-tree, a pine-tree, a myrtle-tree, a box-wood-tree and a balsam-tree have in common?

(d)

How many more trees, besides the cedar itself, belonging to the same family ...

1.

... does the Pasuk in Tehilim list?

2.

... do the Chachamim add to the list, according to the testimony of Rav Dimi?
