Bava Basra 12

BAVA BASRA 12 - dedicated by Rabbi Kornfeld's father in memory of his aunt, Malka Gitel bas Reb Yakov Mordechai (Malvina Marmorstein), who took him into her home and raised him like her own child after the Holocaust. Her Yahrzeit is 20 Nisan.


(a) What does Rabah bar bar Chanah Amar Rebbi Yochanan say about a minor road that leads from town a. through town b., and which the former use to enter the latter, should the latter want to seal its entrance into their town?

(b) We learn from a statement of Rav Yehudah Amar Rav, that this Halachah applies even if there is another way of entering the town.
What does Rav Yehudah Amar Rav say about a path which the public has established as theirs?

(a) On what grounds does Rav Anan Amar Shmuel forbid the residents of a Mavoy to seal the exit from the Mavoy to the main street into which it leads?

(b) We suggest that Shmuel's Din is equivalent to that of Rebbi Zeira Amar Rav Nachman.
What did *he* say about the last four Amos in a Mavoy leading on to the main street.

(c) On what grounds do we refute this suggestion?

(d) What are the ramifications of this rejection?

(a) The Tana Kama of our Mishnah requires each person to receive nine Kabin in a field that is to be divided, Rebbi Yehudah, four and a half.
What is the basis of their Machlokes?

(b) 'bei Radu' is the Arama'ic for 'beis-Nir' (an area that takes a day to plow).
What is the meaning of ...

  1. ... 'Bei Karba'?
  2. ... 'Bei Zar'a'?
(c) Why is a 'bei-Zar'a easier to plow than a bei-Karba'?

(d) Based on this fact, what is the problem with Rav Yosef's statement that in Bavel, each partner has to receive 'bei-Radu Yoma' before one partner may force the other to divide a jointly-owned field?

(a) We resolve the problem in one of two ways. What do we mean when we say 'I Ba'is Eima ...
  1. ... Yoma de'Karba, be'Asra de'Yoma de'Karba ve'Tani' (see Tosfos and Rabeinu Gershom)?
  2. ... Yoma de'Zar'a, be'Asra de'Zar'a ba'Haduri' (see Tosfos)?
(b) What equivalent Shiur does ...
  1. ... Rav Nachman give for a jointly-owned well?
  2. ... Shmuel's father give for a vineyard?
(c) This is substantiated by Sumchus in a Beraisa.
What does Rebbi Yossi comment there on Sumchus statement that if Reuven undertakes to sell Shimon a 'portion' in a vineyard, he is obligated to give him three Kabin?

(d) Rava bar Kisna gives the Shiur in Bavel as three groups of vines.
How many vines must there be in each group? What is the reason for this?

(a) What objection do we raise to Rav Dimi from Chaifa's statement that since the destruction of the Beis-Hamikdash, prophecy was withdrawn from the prophets and given to the Chachamim?

(b) Then what did he really mean to say?

(c) What does Ameimar extrapolate from the Pasuk in Tehilim "ve'Navi Levav Chochmah"?

(a) How does Abaye try to prove Rav Dimi from Chaifa's statement from everyday occurrences?

(b) Rava rejects this proof on the grounds that the two Chachamim are perhaps born under the same Mazel.
How does *he* then present the proof?

(c) Rav Ashi rejects Rava's proof on the grounds that the Chacham might be a bar Mazel at least in that one point.
How does *he* finally prove Rav Dimi's point?

(d) How does he reject the Kashya that maybe the Chacham's statement was just a shot in the dark?

Answers to questions



(a) According to Rebbi Yochanan, after the destruction of the Beis-Hamikdash, when prophecy was withdrawn from the prophets, to whom was prophecy granted instead (see Agados Maharsha)?

(b) Mar bar Rav Ashi was standing in the main street of Mechuza when he overheard a Shoteh announce that whoever signed his name 'Tivyumi', would become the next Rosh Yeshivah in Masa Mechsaya.
Why was that statement of particular significance to him?

(c) So what did he do about it?

(d) Upon his arrival in Masa Mechsaya, why did the Chachamim send a pair of Chachamim to speak to him?

(a) What did Mar bar Rav Ashi do to secure the position of Rosh Yeshivah in favor of Rav Acha?

(b) Why did he wait until he had ten Chachamim before proceeding with his D'rashah?

(c) What was Rav Acha's reaction to Mar bar Rav Ashi's appointment?

(a) We support Rebbi Yochanan's statement regarding children, from the young daughter of Rav Chisda.
What did she once prophecy when, as a little girl, she was sitting on the lap of Rav Chisda her father, whilst his young Talmidim Rava and Rami bar Chama stood in front of him?

(b) It seems that Rava, who would later refer to bas Rav Chisda as his favorite wife, was no less a prophet than she was.
What did he comment following her words?

(a) What does Rav Avdimi learn from the Pasuk in Iyov "Ish Nevuv Yilavev"?

(b) And what does Rav Huna B'rei de'Rav Yehoshua learn from the Pasuk in Zecharyah "ve'Sirosh Yenovev Besulos"?

(c) What does he also say about the Cheilek Bechor and the Cheilek Pashut (of the Bechor)?

(d) According to Abaye, the same applies to a Yavam, since the Torah refers to him as a Bechor ("ve'Hayah ha'Bechor Asher Teiled" [Ki Seitzei]). Rava disagrees.
What does he extrapolate from the words "ve'Hayah ha'Bechor"?

(a) Reuven purchased a field next to his father's.
What did Rabah want to rule, when, after his father's death, he considered it his right to take the field of his father's that was closest to the one that he purchased?

(b) On what grounds did Rav Yosef object to Rabah's intended ruling?

(c) When the two fields that Reuven and his brother inherited, each contained a canal and Reuven claimed the right to take the field closest to the one that he had purchased, Rabah again wanted to uphold Reuven's claim.
What counter argument did Rav Yosef present this time?

(d) So what options could Reuven's brother offer him?

(a) What did Rav Yosef say in a case where the two brothers inherited one field which were both watered by the same canal, and where Reuven asked for the field that was nearest to the field that he had purchased?

(b) On what basis did Abaye protest against Rav Yosef's ruling? (c) Like whom is the Halachah ...

  1. ... in this case?
  2. ... in the previous cases, where Rav Yosef argues with Rabah?
13) The final case in the Sugya concerns a field belonging to two brothers with a river running along the east side and a canal along the north.
Which is the only fair way to divide the property in a way that gives neither brother an advantage over the other?
