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?
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)
