Shabbos 78


(a) Why did the Rabbanan give the Shiur of wine and milk as the amounts that are Chashuv for drinking, rather than the smaller Shiur that went into the eye-cure for which they sometimes used them?

(d) Abaye answers 'bi'Gelila Shanu'.
What does that mean?

(e) How does Rava answer the question - even for people who do not live in the Galil?

(a) The Tana Kama includes blood in the list of liquids whose Shiur is a Revi'is.
Rebbi Shimon ben Elazar and Rabban Shimon ben Gamliel each give the Shiur as enough to paint the eye, the former for a Barkis, the latter for a Ya'arod.

2. ... a Ya'rod?

(c) Our Mishnah gives the Shiur for carrying out Shofchin as a Revi'is. What use do Shofchin have?

(a) The Shiur of the toll-chief's receipt is two large letters.
Does this also require a margin surrounding it?

(b) Rav Sheishes explains that the Beraisa, which gives the Shiur of plain paper as 'large enough to write on it two letters', means two *large* letters, the size that one writes on the receipt.
How does Rava, who explains that the Beraisa means two ordinary-size letters, resolve the Beraisa with the Shiur of 'Kesher Muchsin', given by our Mishnah?

(c) What is the Kashya on Rava from the Beraisa, which writes that 'ha'Motzi Neyar Machuk ... Im Yesh be'Loven Shelo, Kedei Lichtov Shetei Osi'os ... Chayav'?

(a) What does the Tana Kama say about carrying a receipt that he has already shown to the toll-collector?

(b) Rebbi Yehudah maintains that he is still Chayav. According to Abaye, this is on account of the 'Rehitei, Muchsin'; according to Rava, because of 'Moches Gadol u'Moches Katan', and according to Rav Ashi, 'Chad Moches Ika Beinaihu'. What is the meaning of ...

  3. ... 'Chad Moches Iki Beinaihu'?
(a) Someone who carries a paid document in the street is Patur, according to the Tana Kama of the Beraisa.

(c) Will the borrower be Chayav for carrying out the document - according to Rebbi Yehudah?

What will their Machlokes then be?

(b) Rava, like Abaye, establishes the Beraisa when the borrower has not actually paid yet, and both Tana'im hold that without the borrower's admission, the document is worthless to the creditor. Rebbi Yehudah and the Rabbanan argue over whether, or not, one writes a receipt.
What is Rebbi Yehudah's opinion regarding writing a receipt, and why should one therefore be Chayav for carrying out the document?

(c) According to Rav Ashi, it is when the *borrower* carries out the document that Rebbi Yehudah and the Rabbanan argue.
