1)

(a)Why was Rami bar Chana's innkeeper sad?

(b)Why did he decline to retract, when Rami bar Chama advised him to do so?

(c)So Rami bar Chama sent him to Rav Nachman. What did Rav Nachman rule?

(d)When might the seller discover his mistake? Will it affect the Halachah if he does?

2)

(a)How much was that man asking for silk belts that were worth five Zuzim, and how much was he willing to accept?

(b)By what logic did someone purchase them for six Zuzim rather than five and a half?

(c)When they came before Rav Chisda, what did he rule?

(d)Why is there no Ona'ah with regard to someone who buys from a Balabos?

3)

(a)Following a similar incident where a man purchased rings worth fifty Zuzim for sixty, Rav Chisda sent him away disappointed, just like he did in the previous case. What did Rav Dimi and Rebbi Elazar comment on Rav Chisda's ruling?

(b)How did Rav Chisda reconcile his rulings with the following Mishnah, which specifically includes what a Balabos sells in the Din of Ona'ah? What are Tzadraysa?

(c)Our Mishnah includes the seller in the Din of Ona'ah as well as the purchaser, and a merchant who is cheated as well as a Balabos. What does Rebbi Yehudah say?

(d)We already learned above from the Pasuk "ve'Chi Simkeru ... O Kanoh ... Al Tonu" that both the seller and the buyer are subject to the Lav of "Al Tonu". Having taught us that ...

1. ... the seller transgresses, why does the Torah need to teach us that the buyer transgresses too?

2. ... the buyer transgresses, why does the Torah need to teach us that the seller transgresses too?

4)

(a)We learned in our Mishnah that according to Rebbi Yehudah, there is no Ona'ah by a merchant. What is the problem with that statement?

(b)Rav Nachman establishes Rebbi Yehudah by a Safsar. What is a 'Safsar'? What is then Rebbi Yehudah's reason?

(c)Rav Ashi disagrees. What does he mean when he interprets 'Ein Lo Ona'ah' to mean 'Eino be'Toras Ona'ah'?

(d)We would normally rule like Rav Ashi, because he is a later Amora. Why not in this case?

5)

(a)What does the Tana say about the purchaser who has been cheated?

(b)This does not concur with Rebbi Nasan in the Beraisa (quoted on the previous Amud), who holds 'Kanah u'Machzir Ona'ah'. Why does it also not appear to concur with Rebbi Yehudah ha'Nasi opinion there?

(c)Rebbi Elazar is at a loss to know who the author of our Mishnah is. How does Rabah amend Rebbi Nasan in the Beraisa, so as to conform with our Mishnah?

(d)Rava establishes our Mishnah like Rebbi Yehudah ha'Nasi, and the Beraisa, he says, simply complements the missing section in our Mishnah. How does Rav Ashi prove this from our Mishnah?

6)

(a)According to Rav, if Reuven sells Shimon an object adding 'al-Menas she'Ein Lecha Alai Ona'ah', his stipulation is void. What does Shmuel say?

(b)We try and connect this Machlokes with the Machlokes Tana'im. Rebbi Meir in a Beraisa, says that if a man betroths a woman 'al-Menas she'Ein Lach Alai She'er, K'sus ve'Ona'ah', his stipulation is void. Why is that?

(c)Rebbi Yehudah accepts 'Davar she'be'Mamon'. Why? Which of the above constitute Davar she'be'Mamon'?

(d)It seems that Rav holds like Rebbi Meir, and Shmuel, like Rebbi Yehudah. How do we establish ...

1. ... Rav even like Rebbi Yehudah? Why might the latter agree in Rav's case?

2. ... Shmuel even like Rebbi Meir? Why might the latter agree in Shmuel's case?

51b----------------------------------------51b

7)

(a)Rav Anan qualifies Shmuel's ruling. What distinction does he draw between 'al-Menas she'Ein Lecha Alai Ona'ah' and 'al-Menas she'Ein Bo Ona'ah? In which of these cases would his condition be invalid?

(b)Why is that?

(c)Which of the three Dinim will then apply, Mechilah Bitul Mekach or Ona'ah?

8)

(a)We learned in a Beraisa 'ha'Nosei ve'ha'Nosen ba'Amanah, ve'ha'Omer la'Chavero al-Menas she'Ein Lecha alai Ona'ah, Ein lo Alav Ona'ah'. What does 'ha'Nosei ve'ha'Nosen ba'Amanah' mean?

(b)What is the Tana coming to teach us?

(c)Why does the second case in the Beraisa pose a Kashya on Rav?

(d)How does Abaye answer the Kashya?

9)

(a)Rava abides by the alternative explanation (that Rav and Shmuel are not subject to the opinions of Rebbi Meir and Rebbi Yehudah). How does he nevertheless reconcile the Beraisa with Rav"? In which case will Rav concede that his stipulation stands?

(b)Does this distinction apply to the purchaser too, or is it confined to the seller?

10)

(a)If Reuven gives Shimon two sets of wine ba'Amanah, one a good quality wine, and one of poor quality, what condition does the Tana of the Beraisa forbid him to make? Why is that?

(b)What may he stipulate?

(c)And he is obligated to deduct the Sechar Kataf and Sechar Gamal. What is ...

1. ... 'Sechar Kataf'?

2. ... 'Sechar Gamal'?

(d)What else is he obligated to pay him?

11)

(a)Why will there be no problem regarding Ribis if Shimon does not receive part of the profits?

(b)How much did Tzadru'i, for example, get paid for their services? What are 'Tzadru'i'?

12)

(a)Our Mishnah now discusses the Shi'ur of Ona'ah regarding coins. There are four Dinrim in a Sela, and six Ma'ah in a Dinar. How many Pundeyonim are there is a Ma'ah?

(b)And how many Isrin are there in ...

1. ... a Pundiyon?

2. ... a Sela?

(c)According to Rebbi Meir, a deficient Sela is not considered Ona'ah up to four Isrin (one Isar per Dinar). What fraction of the coin is that?

(d)According to Rebbi Yehudah, it is not considered Ona'ah - up to four Pundiyonos, a Pundiyon per Dinar (which is one twelfth). What is the Shi'ur, according to Rebbi Shimon?

13)

(a)In town, the seller is permitted to retract up to the time it takes to show the coin to a banker. What is the time limit in the village?

(b)What does the Tana say about ...

1. ... a deficient coin which the seller returns, provided the purchaser recognizes it? How long after the sale must he accept it?

2. ... using a deficient coin to redeem Ma'aser Sheini?

(c)And what does the Tana mean when he permits its use on the grounds 've'Eino Choshesh, she'Eino Ela Nefesh Ra'ah' (though the connection will be explained later)?
