Why does the Torah add the (otherwise superfluous) word "Zevach Todah"?
Sifra: To incorporate all Korbanos that can be eaten for one day in the Din of Pigul. 1
Such as Chatas and Asham.
What does "li'Retzonchem Tizbachu" mean?
Rashi #1: It means that one should Shecht the Korban Todah with the correct intention - that he will eat it within the one-day time frame prescribed by the Torah in the following Pasuk. 1
Rashi #2: Refer also to Kedoshim, 19:5:2:2*.
Rashi: Since the Torah has already issued the prohibition against eating a Todah after one day (Nosar), in 7:15.
Having already taught the Din of Pigul in Tzav, 7:18 and 19:5, why does the Torah see fit to repeat it here?
Rashi and Seforno (in Pasuk 25): Whereas on the previous occasions, it was referring to a Shelamim, which may be eaten for two days, here, it is teaching us that the same applies to a Todah, which can only be eaten for one day. 1
What is the reason for the Lav of Pigul?
Why does the Torah insert this Pasuk here?
Ibn Ezra and Moshav Zekenim: It is because Todah is eaten for one day, similar to the Isur of Shechitah of a mother and baby in one day. 1
There is a difference however - regarding Todah, 'day' includes the following night, whereas regarding Oso Ve'es B'no, the night is like the following day. (PF)
