Bava Basra 90


(a) The Tana goes on to list the liquid measures that one is permitted to keep in the house: 'Hin, Chatzi Hin, Shelishis ha'Hin, Revi'is ha'Hin, Log, Chatzi Log, Revi'is, Sheminis and Kortov.
How much is a Kortov?

(b) What is the difference between the liquid measure 'Hin' and the solid measure 'Tarkov'?

(c) Continuing with the comparison, if half a Hin is equivalent to half a Tarkav, what is the solid equivalent of the liquid a third of a Hin?

(d) Why did Chazal not institute a liquid measure for an eighth of a Hin (one and a half Lugin)?

(a) What is the equivalent solid measure of the liquid ...
  1. ... Log?
  2. ... Chatzi Log?
  3. ... Revi'is ha'Log?
(b) Why is there no solid measure for an eighth of a Log (half an egg-volume) like there is by its liquid counterpart?
(a) How do we refute the reasoning that Chazal did not institute a solid measure of two Kabin because it is similar to ...
  1. ... a Tarkav (a third more)? What would then be the problem with the Kav measure?
  2. ... half a Tarkav (a quarter more)? What is then be the problem with the Chatzi Tomen ve'Uchla?
(b) How does Rav Papa repudiate the latter Kashya? Why is there no problem with Chatzi Tomen ve'Uchla?

(c) And how do we then explain the fact that they instituted the third of a Hin and the quarter of a Hin measures (since the one is only a quarter more than the other)?

(d) Why did they not decree in the Beis-Hamikdash itself?

(a) What did Shmuel mean when he said 'Ein Mosifin ...
  1. ... al ha'Midos Yoser mi'Shetus'?
  2. ... al ha'Matbe'a Yoser mi'Shetus'?
(b) What third thing did Shmuel add to this list?

(c) Under which circumstances will this third ruling not apply?

(d) Is this prohibition a branch of the La'av of Ona'ah?

(a) Why can Chazal's reason for this Takanah not have been for fear that merchants who bring their wares to sell will raise their prices accordingly (causing the prices to spiral uncontrollably)?

(b) So we suggest that it is because of Bitul Mekach.
What does this mean?
Why will the problem only arise if the prices are raised by *more than* a sixth?

(c) We refute this suggestion too, on the basis of something that Rava said?
What did Rava say that equates Ona'ah with Bitul Mekach in this case?

(a) Perhaps, we then think, the object of the Takanah is to prevent the merchant from making a loss on his sale.
What does this mean?

(b) On what grounds do we refute this explanation too? What does 'Zavan ve'Zavin Tagra Ikri?' mean?

(c) What would Shmuel needed to have said if this had been the reason?

(a) Rav Chisda concludes that Shmuel based his ruling on a Pasuk in Yechezkel.
What does the Navi mean when he writes "ve'ha'Shekel Esrim Geirah, Esrim Shekalim, Chamishah ve'Esrim Shekalim, Asarah va'Chamishah Shekel, ha'Manah"?

(b) Why does he break up the Shekalim in this way?

(c) What does the Pasuk mean when it writes ''Shekel" in this context?

(d) How many ...

  1. ... Geirah are there in a Dinar?
  2. ... Dinrim in a Sela?
Answers to questions



(a) According to Yechezkel, how many Dinrim comprise sixty Shekalim?

(b) How many Dinrim would one normally expect to find in a Manah?

(c) How do we then explain the fact that Yechezkel refers to two hundred and forty?

(d) Which other two interrelated Chidushim can we learn from Yechezkel?

(e) Why is this not considered four Chidushim, and not three?

(a) Rav Papa bar Shmuel introduced a measure of three Kepizi.
How much is that?

(b) We ask how he could do this, in view of Shmuel's prohibition to increase a measure by more than a sixth.
What is the problem? Which measure was being exceeded by more than a quarter?

(c) What could we also have asked from a Tarkav measure?

(d) How did Rav Papa bar Shmuel justify his action?

(e) In Pumbedisa, they did not accept his answer (presumably, because nonetheless, these are official measures, irrespective of the fact that they did not have them), in Papunya they did.
Why did they refer to him there as 'Roz' [or 'Don] Papa')?

(a) Hashem swears that He will never forgive the deeds of four kinds of people, says the Pasuk in Amos: Otzrei Peiros, Malvei be'Ribis, Maktinei Eifah and Mafki'ei She'arim.
What are 'Otzrei Peiros'? Why is this forbidden?

(b) Under which circumstances is it permitted?

(c) Mafki'ei She'arim too, force up the price of the produce in a similar way.
What is the difference between them and Otzrei Peiros?

(d) And what are 'Maktinei Eifah'?

(a) What did Shabsi Otzar Peiri used to do?

(b) Under which circumstances would this be permitted?

(c) What do we mean when we relate how Shmuel's father used to sell fruit 'be'Tar'a Charfa, ke'Tar'a Charfa'?

(d) What did Shmuel his son used to do?

(e) On what grounds did they send from Eretz Yisrael that the deeds of the father were preferable to those of the son? What does 'Tar'a de'Ravach Ravach' mean?

(a) What does Rav mean when he says 'Oseh Adam es Kabo Otzar'?

(b) What does the corroborating Beraisa say about 'Otzar' in time of famine?

(c) Does this mean that one storing crops is prohibited in time of famine?

(d) What does the Tana say about making an Otzar ...

  1. ... of wine, oil and flour?
  2. ... of spice, cumin and peppers?
(a) On what grounds did Rebbi Yossi be'Rebbi Chanina order Puga his slave to store fruits for Erev Shevi'is, Shevi'is and Motza'ei Shevi'is?

(b) On what did he base his ruling?

(c) Seeing as Rebbi Yossi b'Rebbi Chanina was an Amora, why should Sh'mitah have applied in his days (after the Churban Beis-Hamikdash)?
