On the case of one who is ritually impure and eats from the sacrificial foods, whether they are pure or impure, may or may not be liable for the violation. Except that Rabbi Yosi HaGalillee says that person would only be liable if the food he ate was pure. Also, a new mishnah: The stringency of slaughtering outside of the Temple and the offering up there, as well as its leniency. Plus, what happens in the case of lapses in awareness of the offering up outside of the courtyard? It's a dispute - whether that person needs to bring a sin-offering for each separate offering out of that lack of awareness, or not. Also, incomplete offerings - do they incur a liability of the sin-offering, or is one exempt because of the lack of completeness?
