Rif Shabbat 32a


{we have currently digressed to Shabbat 95a, but will shortly return to Shabbat 73b}

He who makes cheese is liable on account of building.
{The solidifying of the liquid is regarded as similar to the act of putting together an edifice.}

{Shabbat 73b resumes}
"BINDING SHEAVES": {vehamaamar}
Rava said: He who collects salt out of a salina {=a salt deposit, formed by causing sea water to flow into a trench} is liable on the score of binding sheaves.
{t partakes of the same nature, and ranks as a derivative thereof.}

Abaye said: Binding sheaves applies only to products of the soil.

They learnt {tana}: Threshing, beating [flax in their stalks], and beating [cotton] are all the same form of work.

{Shabbat 74a}
The Sages learnt {in a brayta}: If various (in parens, in Rif - so should be crossed out: two) kinds of food lie before one, he may select and eat, select and put aside; but he must not select, and if he does, he incurs a sin-offering.

What does this mean?
He may select and eat immediately, and he may select and put aside for immediate use; but he may not select for [later consumption on] the same day, and if he does, it is regarded as though he were selecting for [making] a store, and he incurs a sin-offering.
{But the former does not constitute sifting and is entirely permissible.}

They reported this {statement of Abaye} before Rava, and he said to them: Nachmani {=Abaye} has spoken well.

If two kinds of food lie before a person, and he selects and eats or selects and puts aside {for another to eat}, Rav Ashi learned {matni - I would render had a girsa in this brayta}: He is not culpable; and Rav Yirmiya of Difti learned: he is culpable.
"Rav Ashi learned: He is not culpable":
But it was taught {in a brayta}: he is culpable?!
There is no difficulty: the one treats of a reed-basket and a plate {when the selecting is done by these, he is not culpable}; the other refers to a sieve and a basket-sieve.

Chizkia said: One who picks lupines [after boiling] out of their husks is culpable.
Shall we say that Chizkia holds that it is forbidden to select the eatable from the non-eatable?
Lupines are different,

{Shabbat 74b}
because they are boiled seven times, and if one does not remove it [the edible portion], it goes rancid, hence it is like [picking] the non-edible out of the edible {which is forbidden}.

Rav Papa said: He who cuts up beets very fine is liable on account of grinding.
And Rav Menashia said: He who cuts chips [for fuel] {desalit siltei} is liable on account of grinding.
Rav Ashi said: If he is particular about their size, he is liable on account of cutting {hides - a different labour mentioned in the Mishna}.

By way of explanation of desalit siltei -- this is wood from palms that has a vein-like structure {shivei shivei -- that is, nimin nimin} and when you separate these nimin there goes out from among them something resembling fine flour, and because of this, it as considered like grinding.

Rav Acha bar Ashi bar Avira {our gemara: Rav Acha bar Avira} said: He who throws sikta into a stove {to dry it} is liable on account of cooking.
But that is obvious?
You might say, His intention is to strengthen [harden] the article {whereas cooking softens}, therefore we are informed that it [first] softens and then hardens.

The explanation of sikta -- cakes of animal dung. {Rashi translates - a peg.}

Rava {our gemara: Rabba bar Rav Huna} said: He who boils pitch is liable on account of cooking.

The Sages learnt {in a brayta}: He who plucks the wing [of a bird], trims it [the feather], and plucks it [the down], is liable to three sin offerings.
