Explanation: He should have done so that people would not miss so much time from their work.

Explanation: This is not needed so much for the building.

Implied question: It was needed for the building, so they (ravens) will not bring Tum'ah (carcasses)!

Answer #1: This is not such a big need.

Answer #2: Also, while building it, when the Shechinah did not yet dwell there, it was not needed.

Explanation: Doing the Mitzvah is preferable. Even R. Shimon bar Yochai [who holds that one should not interrupt Talmud Torah to engage in earning a living] holds that one interrupts to make a Sukah and [prepare] a Lulav, like the Yerushalmi says;

However, he holds that one does not interrupt for Tefilah or Keri'as Shema.

Note: This is difficult, for in Shabbos 11a, he holds that we interrupt for Keri'as Shema! (R. Akiva Eiger)

Citation (Yerushalmi): It says about both of these (Talmud Torah and Keri'as Shema) 'Shinenu' ("v'Shinantam", i.e. you will teach them to your children). We do not interrupt one Shinenu for another.

Opinion #1 (Rashi here): This is fixing hair, so it will not scatter.

Question #1: In Shabbos (94b), we say that one is liable for this on Shabbos due to spinning.

Question #2: It should have taught combing, like was taught regarding a Nazir (Nazir 42a)!

Opinion #2 (Rashi Kesuvos 4b): Pokeses is braiding hair.

Question: In Shabbos, we taught Godeles (braiding) and Pokeses! (I.e. they are different.)

Suggestion: Perhaps Pokeses is putting rouge on her face.

Rejection: Both of these were taught [separately] here, and also in Kesuvos!

Opinion #3: We can say that Pokeses is fixing her hair with her hands, outside the kerchief.

Opinion #4 (Riva): Pokeses is putting thin strands of dough on her face to redden the skin. This is why [one is liable for] spinning.

Implied question: Why does the Yerushalmi call this dying?

Answer: It is because it reddens the skin;

Building applies to adorning a woman, based on what it says explicitly in Shabbos (95a) that [Pokeses is liable] due to building. We learn from a verse "va'Yiven [Hash-m Elokim] Es ha'Tzela."

Explanation: In Menachos (86a), it explains that Mor oil (Megilas Esther 2:12) is Sateches. (It seems that this is balsam oil);

[Also] in Megilah (13a), Rav Huna taught in the name of R. Chiya that Mor oil is Sateches.

Note: This is brought also in our Gemara! It seems that this was not in Tosfos' text (Rashash).
