What are the implications of the words "be'Yom Zivchachem Ye'achel ? "?
Rashi #1: It implies that, when Shechting the Korban, one should have in mind to eat it within the prescribed time-period. 1
Rashi #2 (in Yoma, 27b): It implies that the Shechitah of a Korban may only be performed by day but is Pasul by night.
Moshav Zekenim (in Pasuk 5): When you slaughter your Yeitzer ha'Ra, to make peace between you and Hashem, you will eat the Peiros today (in this world), but the principal will be intact for you tomorrow (in the world to come).
Megilah, 20b: It implies that the entire day is Kasher to bring Korbanos. 2
What time-frame is implied by "be'Yom Zivchachem Ye'achel u'mi'Mocharas"?
Rashi, in Yoma, 27b & 28a: Two days and the intervening night.
Hat are the implications of "ve'ha'Nosar ad Yom Shelishi ... "?
Zevachim 56b: It implies that the Shelamm may only be eaten on the second day, but not on the following night. 1
See Torah Temimah, note 18.
The Dinim of Nosar and Pigul are mentioned twice- here and in Tzav, 7:17 & 18. Why, in both locations, does the Torah refer specifically, to the Korban Shelamim.
Oznayim la'Torah: Because regarding other Korbanos that are either entirely burned on the Mizbe'ach or eaten by the Kohanim - who are Zerizim, it is less common to find meat being left over or thoughts that render the Korban Pasul, than by a Shelamim, which are eaten by the owners, who are also likely to ask the Kohen to extend the time of eating by an extra day. 1
See Oznayim la'Torah who elaborates. In any event, he adds, we learn all Korbanos from Shelamim.
