(Mishnah): If Reuven sold wine to Shimon and it soured, Reuven is exempt;

If it is known that Reuven's wine sours, the sale is invalid.

If Reuven said that the wine is scented, it must last until Shavu'os.

'Old wine' is from the previous year;

'Aged wine' must be in its third year.

(Gemara - R. Yosi b'Rebbi Chanina): This is only if the wine was put in Shimon's Keli, but if it remained in Reuven's Kelim, he is responsible (his wine or Kelim are to blame)!

Question: Shimon is to blame for not drinking the wine sooner!

Answer: The case is, he asked to buy wine for cooking.

Question: Why does R. Yosi b'Rebbi Chanina establish the Mishnah when it was put in Shimon's Keli and he asked to buy wine for cooking? He should establish it to discuss Reuven's Keli, and Shimon did not ask to buy wine for cooking!

Answer (Rava): The Mishnah was difficult. It says, if it is known that Reuven's wine sours, the sale is invalid;

Shimon is to blame for not drinking the wine sooner!

We must say that he asked to buy wine for cooking.

R. Yosi b'Rebbi Chanina argues with Rav Chiya bar Yosef.

(Rav Chiya bar Yosef): "Ha'Yayin Boged Gever Yahir" - wine spoils due to its owner.

(Rav Mari): A haughty person is disgraceful even in the eyes of his household - "Gever Yahir v'Lo Yinveh".

"V'Lo Yinveh" hints at people of his Naveh (home).

(Rav Yehudah): If one (who is not a Chacham) wears the Talis of a Chacham (it totally covers his cloak), he does not enter Hash-m's place;

It says here "v'Lo Yinveh", just like "El Neve Kodshecha."

(Rava): If Reuven sold a barrel of wine to a grocer (Shimon) in order to sell it over time (Tosfos; Rashbam - the grocer is merely a Shali'ach to sell Reuven's wine for him) and it spoiled, Reuven suffers the entire loss.

This is only if Shimon did not make a new spout. If he did, it is his fault.

This is only if the market day did not come yet. If it did, Shimon is at fault (he should have sold it then).

(Rava): If Reuven gave wine to Shimon to take to a certain place to sell it, and the price declined by the time he arrived, Reuven suffers the entire loss.

Question: If it soured, what is the law?

Version #1 - Answer (Rav Hillel): Shimon shares the loss (it spoiled due to both of them). This is unlike R. Yosi b'Rebbi Chanina (who blames the spoilage on the owner of the wine and Kelim).

Version #2 - Answer (Rav Hillel): Reuven bears the entire loss, like R. Yosi b'Rebbi Chanina.

(Mishnah): 'Old wine' is from the previous year.

(Beraisa): 'Aged wine' must last until the coming Sukos.

(Mishnah - R. Akiva): If Reuven sold or accepted to build a Chasan's house for Shimon's son or a widow's house for Shimon's daughter, it must be at least four Amos by six Amos;

R. Yishmael says, that is proper for a cattle pen!

One who wants to build a cattle pen should make it four Amos by six Amos.

A small house is six by eight Amos. A large house is eight by 10. A Traklin must be 10 by 10.

The height (of each of these) should be half the sum of the length and width - R. Shimon ben Gamliel says, a proof of this is the Heichal.

(Gemara) Question: Why does the Mishnah mention a Chasan's house for Shimon's son or a widow's house for his daughter? Both apply to sons and daughters!

Answer: This teaches a matter by the way, that it is improper for a Chasan to live in his mother-in-law's house.

(Sefer ben Sira): The lowliest thing is a Chasan who lives in his father-in-law's house;

Worse than this is a guest who invites other guests. Worse than this is one who answers before the other person finished speaking - "Meshiv Davar b'Terem Yishma Iveles Hi Lo u'Chlimah".

(Mishnah): R. Yishmael says, that is proper for a cattle pen!

Question: Who taught the proper dimensions for a cattle pen?

Answer: Some say that R. Yishmael did. Others say that R. Akiva did.

Some say that R. Akiva did. He admits that four by six is proper for a cattle pen, and sometimes a person lives in such a dwelling.

Others say that R. Yishmael did, but R. Akiva would say that a cattle pen should be smaller.

(Mishnah): A Traklin must be 10 by 10.

A Traklin is a hall in which roses are put.

(Beraisa): A Chatzer (for officers) should be 12 by 12.

(Mishnah): The height (of each of these) should be half the sum of the length and width. A proof of this - R. Shimon ben Gamliel says, we learn from the Heichal.

Question: Who taught 'a proof of this'?

Answer #1: R. Shimon ben Gamliel did;

The first Tana asked 'what is a proof of this?' R. Shimon ben Gamliel answered 'we learn from the Heichal.'

Answer #2: The first Tana taught it;

R. Shimon ben Gamliel asked 'Do you learn from the Heichal? Does everyone build like the Heichal?!'

(Beraisa - Others): The height should be like the length of the beams (that span the width of the house).

Question: Why didn't they say 'the height should be like width?

Answer #1: The walls are thicker (so the interior is narrower) at the bottom. He teaches that the height should be like the (greater) width at the top.

Answer #2: There are indentations in which the beams fit. They are slightly longer than the (interior) width of the house.
