Bava Kama 80


(a) When Raban Gamliel's Talmidim asked him whether one was permitted to rear small animals in Eretz Yisrael, he replied in the affirmative. This is obviously a misquotation.
What did they really ask him?

(b) Under what condition did he permit it?

(c) Is his opinion unanimous?

(a) Why did that Chasid follow the opinion of Raban Gamliel? How often did he feed from the goat?

(b) What did his colleagues declare when they came to pay him a visit?

(c) What did they subsequently examine? What was the result of their examination?

(d) What declaration did the Chasid himself make at the time of his death?

(a) According to Rebbi Yishmael's own testimony, why was his father's family wiped out, besides the fact that they would allow their small animals to graze in the forest?

(b) Bearing in mind that grazing small animals in a forest is permitted, why was Rebbi Yishmael's family punished?

(a) What does the Beraisa say about a shepherd who contravenes the above Halachah and subsequently does Teshuvah?

(b) To whom else does this concession extend?

(c) What similar Halachah applies to someone who declared a Neder to purchase a house or to get married in Eretz Yisrael?

(d) Why did a certain woman declare that she would marry the first man who came along? What did the Chachamim rule when unsuitable suitors arrived at her door?

(a) Is there any difference between small Beheimos and small Chayos regarding the above Halachah? What is an example of small Chayos?

(b) Why does Rebbi Yishmael (or Rebbi Shimon ben Elazar) permit keeping small dogs, cats, monkeys and Chuldos Sena'im (weasels) in the house?

(c) What is the alternative explanation of 'Kelavim Kufrim' to small dogs?

(d) What is the mark of Chuldos Sena'im? Where are they found?

(a) Rav made a statement that Bavel had adopted the standard of Eretz Yisrael with regard to rearing small animals.
Why was that?

(b) What did Rav Huna reply when Rav Ada bar Ahavah queried him for keeping a small animal in the house?

(c) What was Rav Ada's reaction to Rav Huna's reply? What effect did it have?

(d) According to the second Lashon, it was actually Rav Huna who introduced the Chumra of Bavel from the time that Rav arrived there. Perhaps he meant that many people came to live in Bavel with the advent of the great Rav.
What else might he have meant?

Answers to questions



(a) What is the difference between a Shevu'a ha'Ben and a Yeshu'a ha'Ben?

(b) It was at one of the two that Rav, Shmuel and Rav Asi could not decide who should enter first. Why did Shmuel refuse to go in before Rav Asi?

(c) Rav refused to go in before Shmuel, as we shall soon see.
What did they decide to do?

(d) Why did they not decide to leave ...

  1. ... Rav outside, and let Rav Asi in first and Shmuel second?
  2. ... Rav Asi outside, and let Shmuel in first and Rav second?
(a) What happened whilst all this was going on?

(b) This prompted Rav to make four statements about cats, two of them that one is permitted to steal them and forbidden to retain them.
What are the other two?

(c) Having taught us that ...

  1. ... one is permitted to kill cats, why did he find it necessary to add that one is forbidden to keep them? Is this not obvious?
  2. ... that they are not subject to theft, why did he find it necessary to add that there is no Mitzvah to return it? Is that too, not obvious?
(d) And how will Rav reconcile his statement with Rebbi Shimon ben Elazar (or Rebbi Yishmael) who, in the Beraisa that we quoted earlier, permits retaining a cat (among other things), in order to keep away the mice?
9) Even though the episode with Rav occurred with a black cat, its mother we point out, was white, whereas the Beraisa is speaking about a black cat whose mother too, was black.
How do we reconcile this with Ravina, who asked a She'eilah whether a black cat whose mother was white is considered black or white?


(a) Rav Acha bar Papa, quoting his brother Rav Aba, who in turn, was quoting his brother Rav Ada (or some other combination of the sons of Rav Papa - see the list of his sons in the text of the Siyum of each Maseches) says that one blows Shofar for a plague of itchy boils. What else did he say about ...
  1. ... a door of opportunity that closes?
  2. ... documenting the sale of a house in Eretz Yisrael?
(b) Why do we need to know the middle Halachah? What difference does it make Halachically?

(c) What does the Beraisa say about 'other communal Tzaros, such as boils that itch, locusts, flies, fleas, snakes and scorpions'?

(d) We reconcile Rav Acha bar Papa (who prescribes blowing the trumpets for boils) with the Beraisa, by citing Rebbi Yehoshua ben Levi.
What did he say about the plague of boils in Egypt (and what is the Beraisa then referring to)?

(a) Mar Zutra explains that the closed door refers to Semichah.
How does Rav Ashi interpret it?

(b) What caused Rav Acha mi'Difti to add that (not only does the door not open quickly, but that once it closes) it will never reopen?

(a) Rav Acha bar Papa also permits documenting the sale of a house in Eretz Yisrael on Shabbos.
Why could he not possibly have meant that?

(b) Then what did he mean?

(c) What does Rebbi Shmuel bar Nachmeini say about someone who buys a town in Eretz Yisrael?
