In the last Mishnah, we spoke about menachot (meal-offerings) that are split between the Mizbeach (altar) and the Kohanim (priests). The kometz (a handful) is burned on the Mizbeach, and whatever is left over is eaten by the Kohanim. This Mishnah will talk about menachot that are not shared whatsoever. Either they are completely burned on the Mizbeach or completely eaten by the Kohanim.
The Mishnah says that all of these four menachot that we mentioned are burned completely on the Mizbeach, and no part of them goes to the Kohanim at all. So we see that, for this group of korbanot (offerings), the privilege the Mizbeach gets from the fact that all of the menachot are burned on it is greater than the privilege the Kohanim get, because the Kohanim do not get any part of this korban (offering) to eat whatsoever.
But now the opposite. The lechem hapanim (showbread), which are offered every single Shabbat, are given fully to the Kohanim to be eaten, and no part of them is burned on the Mizbeach. For this group of korbanot, the privilege of the Kohanim is greater than the privilege of the Mizbeach, in that the Kohanim eat the entire portion of it, and none of it is offered on the Mizbeach.
