Bava Basra 89

BAVA BASRA 89 - dedicated on the occasion of the Shloshim of Reb Dovid Tuvia ben Harav Yechiel Mechel Halevi (David Kramer), by the Lomdei Daf Ha'Yomi in White Oak, Maryland (Jack Delman, Howie Feldman, Yitz Gedalowitz, Shlomo Katz, Jay Levine, Rabbi Sanders, Kenneth Schor, Raanan Shames, and Sheldon Meth). David was a founding member of the White Oak Daf Ha'Yomi, a frequent Magid Shiur, and an integral part of its continuation for over 10 years. David was also a pillar of the White Oak community for over 25 years. May his memory serve as a blessing for all of Klal Yisrael!


(a) May one compress the contents of the measure when it is customary to heap them or vice-versa, with the consent of the purchaser or the seller (respectively)?

(b) If we learn this from the Pasuk in Ki Seitzei "Eifah Sheleimah ... Yih'yeh Lach", what do we learn from the word "va'Tzedek"?

(c) How much would the seller need to deduct from the price, were he to be permitted to compress the measure provided he deducted from the price?

(d) Following exactly the same pattern, what do we learn from the continuation of the Pasuk ...

  1. ... "Even Sheleimah ... Yih'yeh"?
  2. ... " ... va'Tzedek"?
(a) What does Rav Yehudah mi'Sura learn from the Pasuk "Lo Yih'yeh Lecha ...

  2. ... *be'Kischa" ... Even va'Aven, Gedolah u'Ketanah"?
(b) What does the Beraisa Darshen from the Pasuk "Even Sheleimah va'Tzedek *Yih'yeh Lach*"? To whom is the Torah speaking?

(c) Why does the Tana not consider this necessary when it comes to price control, in order to penalize those who raise their prices?

(d) What did the B'nei Nesi'ah nevertheless used to do?

(a) Why did a 'horn of flesh' grow on Karna's eye?

(b) Why did Shmuel choose specifically that?

(c) Did Karna have a source for his ruling?

(d) What does the Beraisa mean when it rules that one fulfills the request of the purchaser to sell a Litra, half Litra or a quarter of a Litra?

(a) How does the Beraisa require the weighing of three-quarters of a Litra?

(b) And what does another Beraisa say about a purchaser who insists that the seller weighs him ten Litras, a Litra a time?

(c) What do these two Beraisos have in common? Why not three times a quarter of a Litra in the first Beraisa, and why not one Litra ten times in the second, if that is what the purchaser wants?

(a) What does the Tana of the Beraisa mean when he gives the measurement of the arm and the two strings of the scales with which one weighs metals, as twelve Tefachim?

(b) What is the minumum length of the 'Nefesh' (the metal tube that runs from the ceiling to the arm, through which the cord that holds the arm [the 'Lashon' runs])?

(c) How far from the ground must the scales be?

(d) What is the reason for these two measurements?

(a) The scales of wool-merchants and glaziers must be at least two Tefachim from the ceiling and two Tefachim from the ground.

What does the Tana say about the length of the arm and the two strings?

Answers to questions



(a) What does Rebbi Mani bar Patish mean when he says (with regard to the scales) 'Just as they said concerning the Isur, so too, did they say concerning Tum'ah'?

(b) We query the need for his statement however, from a Mishnah in Keilim. What does the Tana say there about the string by which the scales of a store-keeper and a private person hangs from the ceiling?

(c) How do we reconcile Rebbi Mani with the Mishnah in Keilim?

(a) Why does the Tana forbid scales of tin, lead, Gistron or any other kind of metal? What is Gistron?

(b) Out of which raw material may one make the scales, besides glass?

(b) What made him decide to teach them after all?
(a) The Pasuk in Kedoshim writes "Lo Sa'asu Avel ba'Mishpat, ba'Midah, ba'Mishkal u'va'Mesurah". How do we know that "ba'Midah" refers to the measuring of land and not of a measuring-vessel to measure liquids?

  1. ... here?
