Bava Basra 19

BAVA BASRA 19 (26 Nisan) - has been dedicated by Mr. Avi Berger (Queens, N.Y.) in memory of his mother, Leah bas Michel Mordechai in honor of her Yahrzeit.


(a) We learned in our Mishnah that Reuven must move his laundry-pit three Tefachim from the wall of Shimon's pit (i.e. three Tefachim from the border).
How does Rav Nachman Amar Rabah bar Avuhah qualify this? When are four Amos required?

(b) How do we substantiate Rav Nachman's distinction?

(c) According to Rav Chiya B'rei de'Rav Ivya's text in our Mishnah, the matter is clearer still.
What is his version of our Mishnah?

(a) We conclude the first group of prohibitions listed in our Mishnah ('Bor Samuch le'Boro ... ') with 've'Sad be'Sid', and we ask whether it should not perhaps read 'O Sad be'Sid'.
How do we attempt to resolve the She'eilah, based on the second group of prohibitions ('es ha'Geffes ... ')?

(b) How do refute this proof? Why might the Tana state 'O Sad be'Sid' in the Reisha too, and still list them as two sets?

(c) We cite the Beraisa where Rebbi Yehudah requires both neighbors to dig their pits in 'Sela ha'Ba be'Yadayim' three Tefachim from the border and to cement them with lime.
How do we try to resolve our She'eilah from there?

(d) How do we refute this proof, too?

(a) We learned in a Mishnah in Shabbos 'Ein Tomnin Lo be'Geffes, ve'Lo be'Zevel, ve'Lo be'Melach, ve'Lo be'Sid, ve'Lo be'Chol'.
What is the glaring discrepancy between that Mishnah and ours?

(b) Abaye cites the Beraisa 'Tomnin be'Gizei Tzemer ... u'vi'Leshonos shel Argaman'.
How does this Beraisa pose a Kashya on Rav Yosef's answer? What did Rav Yosef say?

(c) Abaye therefore answers 'Yagid Alav Re'o'.
What does he mean by that?

(d) How does Rava refute Abaye's answer?

(a) How does Rava finally answer the Kashya.
Why does the Tana ...
  1. ... there (by Hatmanah) omit rocks'?
  2. ... here (by damages) omit sand?
(b) How do we reconcile this with Rebbi Oshaya, who forbids Reuven to place his sand within three Tefachim of Shimon's wall?

(c) Our Tana does not find it necessary to insert wet sand however, since he has already included a stream of water.
How do we then account for his insertion of a laundry-pit, despite his already having mentioned a stream of water?

(d) Why would we not have known ...

  1. ... a laundry-pit from a stream of water?
  2. ... a stream of water from a laundry-pit?
(a) We learned in our Mishnah that Reuven must distance his seeds and his plow at least three Tefachim from Shimon's wall.
Why does the Tana need to insert ...
  1. ... seeds, seeing as someone who seeds will inevitably plow?
  2. ... plowing, seeing as this is followed by seeding, which he has already mentioned?
(b) But have we not already learned that watering is harmful to a wall, so why does he need to mention plowing at all, seeing as trees require watering? What do we learn from the Pasuk in Eikev "li'Metar ha'Shamayim Tishteh Mayim"?
Answers to questions



(a) The Mishnah in Kil'ayim forbids seeding the area directly above a replanted branch of an attached vine.
What does the Tana of the Beraisa comment on this Mishnah?

(b) Why must the Tana be speaking about a solitary vine (or even up to four vines)?

(c) Clearly then, seeds grow upwards and not sideways.
How does Rebbi Chaga quoting Rebbi Yossi explain our Mishnah, which requires a distance of three Tefachim between Reuven's seeds and Shimon's wall?

(a) How does Rabah bar Rav Huna learn from the Pasuk in Melachim "ve'Hichrati le'Achav Mashtin ba'Kir ... "?

(b) Then how does he explain our Mishnah 've'es Mei Raglayim min ha'Kosel Sheloshah Tefachim'?

(c) On what basis is Rabah bar Rav Huna proved wrong?

(d) What distinction does the Beraisa make between a wall of bricks and a wall of stones?

(e) How do we then explain the Pasuk in Melachim? What does Mashtin ba'Kir' refer to?

(a) What does Rav Tuvi bar Kisna Amar Shmuel mean when he says 'Rakik Eino Mema'et ba'Chalon'?

(b) Does this mean that a thick loaf does diminish the space?

(c) Seeing as anything that is subject to Tum'ah does not prevent Tum'ah from passing through, what is the Chidush?

(a) We ask on Shmuel from a Beraisa.
What does the Tana say about a box full of straw or a barrel full of dried-figs which is lying on a window-sill that divides between a room in which there is a corpse and another room? Under what conditions will the straw or the figs prevent the Tum'ah from passing into the second room?

(b) How can the straw prevent the Tum'ah from passing through under any circumstances, seeing as it is fit ...

  1. ... to be fed to his animals?
  2. ... for making cement?
  3. ... for fuel?
(c) But surely it is fit to fuel a big fire?

(d) And by the same token, how can the figs prevent the Tum'ah from passing through, seeing as they are fit to eat?

(a) Why does the barrel itself (that contains the figs) not prevent the Tum'ah from passing through, despite the fact that the outside of an earthenware barrel is not subject to Tum'ah and is therefore Chotzetz before Tum'ah?

(b) How could we establish the Beraisa even if it is the back of the barrel that was facing the corpse?
