Rif Shabbat 18a



HIDE/SHOW IMAGE
18a

{Shabbat 38b continues}

A kippah has room for placing one pot.

MISHNA:
ONE MUST NOT PLACE AN EGG AT THE SIDE OF A BOILER FOR IT TO BE ROASTED {lit. 'that it should be rolled'}, AND ONE MUST NOT BREAK IT INTO A [HOT] CLOTH; BUT R. JOSE PERMITS IT.
AND ONE MAY NOT PUT IT AWAY IN [HOT] SAND OR ROAD DUST FOR IT TO BE ROASTED.

Gemara:
It was a question to them: If he did roast it {lit. roll it} what {is the law}?
Rav Assi {our gemara: Rav Yosef} said: If one roasts it, he is liable to a sin-offering.
Mar Zutra {our gemara: Mar the son of Ravina} said: We learnt likewise {in a brayta}:

{Shabbat 39a}
That which came into hot water before the Sabbath may be steeped in hot water on the Sabbath; but whatever did not come into hot water before the Sabbath, may be rinsed with hot water on the Sabbath, except old salted [pickled] fish and the colias of the Spaniards, because their rinsing completes their preparation.

"AND HE MUST NOT BREAK IT INTO A [HOT] CLOTH. AND RABBI YOSSI PERMITS":
And this that we learnt {tnan}: "We may place cold water in the sun to be heated" - shall we say this is Rabbi Yossi, and not the Sages {who argue with him in the Mishna}?
Rav Nachman bar Yitzchak said: In the sun, all agree that it is permitted. In a fire-heated object, all agree that it is forbidden. When do they argue? In a sun-heated object. The Sages hold that we decree on a sun-heated object because of a fire-heated object, and Rabbi Yossi holds that we do not decree.

And the halacha is like the first Tanna {that is, the Sages}.

"AND ONE MAY NOT PUT IT AWAY IN [HOT] SAND":
And in this, even Rabbi Yossi agrees.
What is the reason?
Rabba said: It is a decree lest he insulate in hot ashes.
And Rav Yosef said: It is a decree lest he move earth [sand] from its place.
What is the difference between them?
In respect of crushed earth. {Where Rav Yosef's reason does not apply, since it is already before him}

MISHNA:
IT ONCE HAPPENED THAT THE PEOPLE OF TIBERIAS DID THUS: THEY CONDUCTED A PIPE OF COLD WATER THROUGH AN ARM OF THE HOT SPRINGS.
SAID THE SAGES TO THEM: IF ON THE SABBATH {the water is drawn through the pipe}, IT IS LIKE HOT WATER HEATED ON THE SABBATH, AND IS FORBIDDEN BOTH FOR WASHING AND FOR DRINKING;
IF ON A FESTIVAL, IT IS LIKE WATER HEATED ON A FESTIVAL, WHICH IS FORBIDDEN FOR WASHING BUT PERMITTED FOR DRINKING.

{Shabbat 39b}
Gemara:
Ulla said: The halachah agrees with the inhabitants of Tiberias.
Rav Nachman said to him: The Tiberians have broken their pipe long ago! {and thus they have retracted from their opinion}

And the halacha is like Rav Nachman.
