שבת דף סד עמוד א

¹"She'Ani Mirabeh" (Maybe I should include measuring equipment which is made from this material. Nope, since it is not twined and woven.

²Since we used "כל" for Horse equipment, maybe we should include measuring equipment as well

³The "Din" should show us the opposite. Irregardless of the word "כל", the laws should be the same for both שרץ and מת

⁴The Gemara proves that the "Din" doesn;t Dan since מת is more stringent than שרץ which is the source of the leniency by unwoven measuring items. So perhaps no such leniency would be afforded by מת.

⁵But the word או is already used to include horse stuff

⁶Now that we can use the Gzera Shava and borrow the כל of מת and apply it to שרץ, the word או by שרץis freed up for something else.

⁷I'm not sure why the existing Gzeira Shava is not in effect. Doesn't it travel both ways?

⁸A broader range of material ius asur for one day, so stuff made of horsehair, etc., while טמא for שרץ maybe should not be טמא for מת.

⁹Sre these words really free, since if they are needed for learning out a law, the Gezeira Shava won't work since Sharatz requires but a small amount to be mtamei. מת requires a כזית as opposed to an עדשה.

¹⁰And we have what to be משיבין since, as stated before since the quantity required for Tuma מת is greater, so how do we know that we can borrow כל, used to include horse equipment for מת, and apply it to שרץ?

¹¹So it's obvious that a קטנה might remove an old woman's wig, and therefore it should be אסור to wear it out on שבת!

¹²It's תנא vs. תנא, not אמורא vs. תנא.

¹³What makes these items permissable to wear in a חצר?

¹⁴The implications ar far reaching in my opinion. Rabbi Akiva makes a limus on a verse based on a forgone conclusion that he wants to uproot a previous limud which led to a gezeira that was causing difficulties. Or does he feel that the Gezeira (admittedly not a Torah law even by the implementers) was based on a poor understanding of the verse. This poor understanding led to a downgrade of women, and caused divorces. Therefore Rabbi Akiva made a limud with no Halakhik applications, just philisphical social ones, and uprooted the Gezeira. But it DID have implications: water is required to get rid of Nidda even after 7 days. But wasn't this known previously?

¹⁵Even though the Pekak is a problem because of מרעית העין, maybe the guy is taking ithe cow to be sold on Shabbat, it is still permissible in a חצר since no one can see.
