Question: Citing the Riva, the Ri quotes the Yerushalmi, which asks why Erev Pesach should be different than every other Yom-Tov?

Answer: And it answers that it is because the time to bring the Korban Pesach is from midday and onwards; in fact, an individual who brings a Korban on any day of the year is obligated to abstain from work the entire day.

Question: In that case, asks the Yerushalmi, why does the Minhag not to work on Erev Pesach not also extend to the entire day, like a Yachid on any other day?

Answer: And the Gemara answers there, that because a Yachid on any other day is eligible to bring his Korban already from the morning, whereas the Pesach can only be brought after midday, as we learn from the Pasuk " ... bein ha'Arbayim".

Question: That being the case, the Korban Tamid, which is brought every day by the whole of Yisrael, every day work ought to be prohibited.

Answer: And the Gemara there answers precludes the Tamid from the general rule, when it writes " ... and you shall gather your corn". Now if of Yisrael were sitting idle, who would be gathering the corn?

Conclusion: It is implied there that the prohibition is mi'd'Oraysa. Consequently, t would seem, that even nowadays when the Korban Pesach is not brought, since work was forbidden then, it remains forbidden forever.

Clarification: The Ri explains it in accordance with the Yerushalmi, which states that 'The Minhag that women have not to perform Melachah on Motza'ei Shabbos is not a Minhag; whereas the Minhag not to do Melachah until the completion of the 'Sidra', is.

Clarification (cont.): This means that (not to do Melachah) until the termination of the Tefilah is a Kasher Minhag. And that is what the Gemara is referring to here.

Question: Rava himself says in the second Perek of B'rachos (Daf 17.) that whoever studies Torah 'she'Lo li'Shemah' (for the wrong motives), it would have been better had he not been born?

Answer: The Ri explains that it speaks there about someone who learns in order to boast, and to chide his colleagues and to prove them wrong, rather than to fulfil the Mitzvos.

Answer (cont.): Whereas here it is speaking in a case similar to what we learned earlier 'There are some who are laid back and benefit' - with reference to someone who does not work the entire week and who dos not work on erev Shabbos either.

Answer (concl.): They intend no evil, and what they do is based on laziness. Nevertheless "Your kindness reaches up to the Heaven!"

Clarification: This refers to spinning. And the reason that it is called 'Maskulta' (from the root od 'Mask'la' - weight) is because she hires herself out by the weight of wool that she spins.

Source: As we learned in the Mishnah in Kesuvos (Daf 64:) 'How much must she spin for him? A weight of five Sela'im ... '.

Conclusion: Rabeinu Chananel explains that she is shamed by this job, since her arms tends to become uncovered whilst she spins.

Question #1: Rabeinu Tam asks from the Gemara in Chulin (Daf 84:), which states that 'Someone who wishes to become rich should deal with small animals (i.e.sheep)'?

Question #2: And likewise, commenting on the word "Asht'ros", they explain there 'that they enrich their owners'.

Answer: Those Gemaros are speaking about the forests, which are not inhabited.

Clarification: The Ri explains that it is specifically those who write in order to sell that made tis request, since they will always find customers ...

Proof: As the Beraisa says 'They and their merchants ... '.

Conclusion: But they did not make the request with regard to those Sofrim who hire themselves out to Ba'alei-Batim, in order not to interfere with their source of income, since one cannot always find people who want to hire a Sofer.

Question: How can one possibly err, seeing as it is anyway forbidden to separate one species on another one?

Answer: When the species are mixed it is possible to err, since there is no prohibition against separating one kind on the other, as we explained in Perek Kol Sha'ah (above on Daf 35.).

Conclusion: And it is in such a case one suspects that perhaps the dough is larger on the side where the rice is, and one comes to take from that side to cover the other one.
