Bava Basra 17


(a) What does the Tana of the Beraisa learn from the three Pesukim "va'Hashem Beirach es Avraham ba'Kol" (Chayei Sarah); "va'Ochal mi'Kol" (Toldos) and "ve'Chi Yesh Li Kol" (Vayishlach)?

(b) What does he possibly learn from the Pasuk "ve'Libi Challal be'Kirbi" (Tehilim) as well?

(c) How alternatively, might we explain the latter Pasuk?

(a) What does the Tana say about the Avos plus Moshe, Aharon and Miriam?

(b) The Avos belong in this list, because of "ba'Kol", "mi'Kol", "Kol"; Moshe and Aharon, because the Torah writes by both of them "al-Pi Hashem". But on what basis does he insert Miriam?

(c) Why does the Torah not then use this phrase in connection with her, too?

(a) What do the above six and Binyamin ben Ya'akov have in common?

(b) From where do we know this to be the case by ...

  1. ... Moshe, Aharon and Miriam?
  2. ... Binyamin ben Ya'akov? What does the Torah write about him in Vayechi?
(c) And what does the Tana learn from the Pasuk in Tehilim "Af Besari Yishkon la'Vetach"?

(d) Why is this Pasuk not such a good proof?

(a) And what do Binyamin ben Ya'akov, Amram, Moshe's father, Yishai, David's father and Kil'av his son, have in common?

(b) From where do we know the first three?

(c) Based on the Pasuk in Divrei Hayamim, Tzeruyah's three children were called Avshai (better known as Avishai), Yo'av and Asa'el.
What was the name of Tzeruyah's ...

  1. ... sister?
  2. ... famous brother?
(d) The Pasuk in Shmuel refers to her as "bas Nachash".
What is the connection between Amram and a snake? Which snake?

(a) How close to Shimon's pit does our Mishnah permit Reuven to dig a pit, trench, cave or stream of water?

(b) The same applies to digging a Nivreches Kovsin.
What is a 'Nivreches Kovsin'?

(c) Why is this three-Tefach distance necessary?

(d) What must Reuven do in addition, in order to prevent damaging Shimon's pit?

(a) The Tana does not forbid Reuven to place his Geffes (the remains from the olive-press), manure, salt, lime or flint-rocks beside Shimon's pit.
Where *does* he forbid him to place them? What alternative solution is there to safeguard Shimon's wall?

(b) How close to Shimon's wall does the Tana permit Reuven to place his seeds and plow, as well as to urinate?

(c) In what way does a mill harm the wall next to which it is placed?

(d) Reuven is forbidden to place his Shechev (the lower mill-stone) within three Tefachim away from Shimon's wall.
How close may the Rechev (the upper mill-stone) be?

(a) In what way does an oven harm the wall next to which it is placed?

(b) What is the purpose of the base of cement and bricks that they would make for a Tanur (an earthenware high-temperature oven with its opening on top)?

(c) Reuven is forbidden to place the Kalya (the foot of that base) within three Tefachim of Shimon's wall. How close may the Shafah (its top) be?

Answers to questions



(a) How does Abaye (or Rav Yehudah) account for the fact that the Tana begins talking about Reuven digging a pit near Shimon's *pit*, and ends with how far he must keep away from his *wall*?

(b) Why, had the Tana merely said that he must keep away from Shimon's pit, would he anyway have had to mean from the wall of the pit, and not the pit itself?

(c) Then why does he find it necessary to mention the wall at all?

(d) Why do we need to know this?

(a) Abaye permits Reuven to dig a pit at the edge of his field where it adjoins Shimon's.
On what grounds does Rava disagree?

(b) Their Machlokes is confined to a field which is not meant for pits. What will they hold with regard to a field which is? What is an example of a field which is meant for pits?

(c) In the second Lashon, they argue over a field which is meant for pits. What will they hold with regard to one which is not?

(a) Abaye permits placing his pit beside the border even according to the Rabbanan, who obligate someone planting a tree to leave a space of at least twenty-five Amos between his tree and his neighbor's pit.
Why is that?

(b) Whereas Rava forbids it even according to Rebbi Yossi, who permits planting it right up to the pit.
Why is that?

(c) We learned in our Mishnah that Reuven may not dig a pit beside Shimon's, implying that had there been no pit there, it would have been permitted.
How will Rava establish the Mishnah according to the second Lashon, where he argues with Abaye in the case of a field that is meant for pits?

(d) On whom is the Kashya, according to the other Lashon?

(a) To answer the previous Kashya, Rava cites what Abaye (or Rav Yehudah) said earlier 'mi'Kosel Boro Lamadnu'.
How does this answer the Kashya?

(b) Another Lashon cites our Mishnah 'Lo Yachpor Adam Bor Samuch le'Boro shel Chavero', together with Abaye (or Rav Yehudah)'s qualifier 'mi'Kosel Boro Lamadnu'.
Why is there no problem according to the Lashon that establishes the Machlokes Abaye and Rava by a field which is not meant for pits?

(c) How will Abaye explain our Mishnah, according to the Lashon that establishes the Machlokes by a field which is meant for pits?

(a) What does the Beraisa say about a Sela ha'Ba be'Yadayim'? What is a 'Sela ha'Ba be'Yadayim'?

(b) Assuming that the Tana speaks when each one comes to dig independently (see Tosfos DH 'Hachi Garsinan'), how will Abaye explain the Beraisa?

(c) Then what made us ask the Kashya in the first place? If, as we initially thought, the Tana speaks about any field, then why did he present the case of 'Sela ha'Ba be'Yadayim'?
