(a) According to our Mishnah, a Shomer deducts nine half-Kabin per Kur for
wheat and rice.
How much does he deduct for ...
(b) How many Kabin are there in a Kur?
- ... barley and millet?
- ... spelt and flax seeds?
(c) According to the Tana Kama, the above Shiur is both per Kur and per
What does Rebbi Yochanan ben Nuri say?
(a) According to Rebbi Yehudah, if the Shomer is looking after many Kurin,
he does not need to deduct
What is the Shiur of 'many Kurin'?
(b) What is Rebbi Yehudah's reason?
(c) What problem do we have with the Tana's Shiur for rice (nine half Kabin
(a) The Beraisa corroborates the statements of Rabah bar bar Chanah Amar
Rebbi Yochanan and Rebbi Yochanan Amar Rebbi Chiya.
(b) What would the Din be with regard to pure flax-seeds without the stalks?
- ... Rabah bar bar Chanah Amar Rebbi Yochanan say (in answer to the Kashya we just asked) concerning the Shiur of rice in our Mishnah?
- ... Rebbi Yochanan Amar Rebbi Chiya say about the flax-seeds in our Mishnah?
(c) How do the Rabbanan (quoted in a Beraisa) counter Rebbi Yochanan ben
Nuri's argument that the mice do not eat more because there are more Kurin?
(a) Our Mishnah specifies how much one deducts for the losses of the various
commodities listed in the Mishnah.
Why is the Shomer responsible for those
losses? Why can he not just return whatever there is, and whatever is lost,
(b) Then why can the Shomer not just ...
(c) Rabah bar bar Chanah gives the Shiur of Midah Merubah (of Rebbi Yehudah)
as ten Kur.
- ... separate his own crops from the Pikadon and return the rest?
- ... assess how much he used and deduct it from the total?
How do we prove that this Shiur is correct?
(a) A Beraisa expert cited a Beraisa confining our Mishnah (which deducts
the Chesronos) to a case where the owner gave the Shomer the corn in the
barn, and the Shomer returned it in the barn, but not when he returned it
from the house.
(b) Why did Rav Nachman reject this version of the Beraisa?
(c) How did he therefore amend it?
(d) Rav Papa asked Abaye why, in that case, jars of produce that are kept
from the summer to the winter do not burst. It happened once that such a jar
Why do other jars burst? Why did that jar do so? (See Shitah
(a) The Tana Kama gives the Shiur of Chesronos for wine (that the Shomer
mixed with his own) as a sixth (because that is how much becomes absorbed in
What does Rebbi Yehudah say?
(b) Our Mishnah he gives the Shiur for the loss of oil as three Lugin per
How does the Tana divide this into two different causes?
(c) What will the Din therefore be ...
(d) What does Rebbi Yehudah say about someone who purchases pure oil in the
course of the year?
- ... if the oil is purified?
- ... if the oil is stored in an old barrel?
(a) If the Tana Kama and Rebbi Yehudah in our Mishnah do not argue, then
(aside from the possibility that they used different kinds of earthenware)
why does the former give the Shiur for wine as a sixth, and the latter, as a
(b) When Rav Yehudah became a wine-merchant, he sold wine which he had
bought for six Zuz per barrel at six Kuzim per Zuz. Seeing as each barrel
contained forty-eight Kuzim, how much profit was Rav Yehudah now making (in
Kuzim), after deducting a sixth (eight Lugin [like the Tana Kama of our
(c) How much profit is a merchant permitted to earn for a livelihood?
(d) Then why did Rav Yehudah not allow himself a profit of another two Kuzim
to make up the sixth?
(a) How do we then account for the fact that the four Kuzim plus the barrel
and the dregs add up to more than a sixth, which is in excess of the
maximum profit permitted?
Answers to questions
(b) 'Barzenaysa' refers to the cost of fitting a tap to the barrel. Others
have the text 'Karzenaysa'.
What does 'Karzenaysa' mean?
(a) We learned in our Mishnah that if the wine is placed in old barrels, the
Shomer does not contend with asorption. To answer the Kashya 've'Ha I
Efshar de'Lo Bala?', Rav Nachman establishes the Mishnah by barrels that
have been lined with pitch.
But did we not learn earlier that the pitch
itself absorbs (see Tosfos)?
(b) How does Abaye answer the Kashya?
(c) Rebbi Yehudah permits a seller of pure oil to give the purchaser one a
half Lugin of dregs per hundred Lugin. The Chachamim forbid it.
Abaye explain the basis of their Machlokes? On what grounds does Rebbi
Yehudah permit adding dregs?
(d) Why can the purchaser not argue that ...
- ... had he received the dregs mixed with the oil, he could at least have sold them, whereas as a separate entity, they are useless to him?
- ... the fact that the seller did not mix them indicates that he was Mochel them?
(a) In the Mishnah in Bava Basra, the Tana Kama holds that someone who buys
a yoke has not automatically bought the oxen, and vice-versa.
Rebbi Yehudah say?
(b) What is the basis of their Machlokes?
(c) Rav Papa disagrees with Abaye's interpretation of Rebbi Yehudah and the
Rabbanan in our Mishnah.
How does he explain it, using the reverse logic?
(a) The Beraisa equates a buyer with a depositor with regard to Piktim.
What are Piktim?
(b) Why can he not mean that a depositor, like a buyer, does not need to
(c) Then what *does* he mean?
(a) Why does Rebbi Yehudah say in a Beraisa, that the seller is obligated to
retain the Piktim?
(b) How do we reconcile this with the previous Beraisa, which obligates the
purchaser to accept the Piktim?
(a) If someone deposited a barrel by his friend without designating a fixed
location for it, and the barrel broke whilst he was moving it, what
distinction does the Tana of our Mishnah make, depending upon why he was
(b) What does he say in a case where it broke ...
Answers to questions
(c) We establish the Reisha of the Mishnah, which exempts the Shomer from
paying once he has replaced the article, like Rebbi Yishmael.
- ... after he replaced it?
- ... either before or after he replaced it, if the owner designated a specific location?
Rebbi Yishmael say in a Beraisa with regard to someone who stole a lamb from
someone's flock or a Sela from someone's purse? What is the basis of this
(d) What Rebbi Akiva say?
(e) Why does the Tana of our Mishnah refer specifically to where the owner
did not designate a location for the barrel?
