English: “And it shall be the kohen’s like the meal-offering” — if this sinner is an ordinary Israelite, its remainder is eaten by the kohen; if this sinner is a kohen, it is like a kohen’s voluntary mincha — wholly burnt, not eaten.
In Menachos / Sifra: The plain sense gives the remainder to the kohen. The midrashic reading adds: when the offerer himself is a kohen, the flour-chatas follows the rule of a kohen’s own mincha and is entirely consumed on the altar.
Type of Learning
Custom (status of the offerer changes the fate of the remainder).
What Is Learned
A non-kohen’s flour-chatas leaves edible remainder for the kohen; a kohen’s own flour-chatas is burned entirely and may not be eaten.
