What are the implications of the word "b'Mo'ado"?
What is the definition of "Chukosav" in this context?
Rashi #1: "Chukosav" refers to Mitzvos concerning the body of the animal - "An unblemished male lamb in its first year".
What is the definition of "Mishpatav"?
Rashi #1: It is Mitzvos related to the Korban Pesach - such as eating Matzah for seven days and destroying one's Chametz. 1
Rashi #2: Mitzvos connected with the body of the animal are "roasted ... its head, its legs and its innards"; Mitzvos outside the body - Matzah and destroying one's Chametz. 2
Why does the Torah write "Ta'asu oso" twice?
Ramban: Once with regard to the preparation of the Korban Pesach in the afternoon, and once with regard to eating it at nighttime. 1
Rashi writes that b'Mo'ado implies 'even on Shabbos' and 'even b'Tum'ah'. Pesach is not brought b'Tum'ah, rather, one offers Pesach Sheni!
Moshav Zekenim: If the entire [or majority of] the Tzibur is Tamei, they offer Pesach b'Tum'ah.
Moshav Zekenim: Some say that if all [or most of] the Kohanim are Temei'im, they offer Pesach b'Tum'ah, but if the entire Tzibur is Tamei, they do not. This requires investigation (for Pesachim 79a says that in both cases, or if most of the Klei Shares are Tamei, they offer Pesach b'Tum'ah
Rashi writes that Mitzvos related to the animal, e.g. eating Matzah for seven days and destroying one's Chametz [apply to Pesach Sheni]. These do not apply to Pesach Sheni!
Ramban, Moshav Zekenim: The correct text of Rashi is like his second version (refer to 9:3:3:2).
Moshav Zekenim: Some texts of Rashi say 'l'Shiv'ah' (without the word 'Yamim'). Really, it is l'Sovah, that it is eaten when satiated. This requires investigation. 1
Perhaps it is difficult because it should have said 'Al ha'Sova', and without a Hei at the end. And this did not explain 'destroying Chametz.' (PF)
