Zevachim 45 - October 29, 7 Cheshvan

The halakha was decided according to the opinion of Rabbi Elazar in the name of Rabbi Shimon regarding pigul in the inner sin offerings. Rava (and some say Rav Yosef) wondered: Why is halacha being decided on a matter that is no longer relevant in our times? To this, Abaye responded: "Expound and receive reward." Is there a difference between offerings brought by non-Jews and those brought by Jews? Rabbi Shimon and Rabbi Yosi disagree on this matter. From which verses does Rabbi Shimon derive that certain laws do not apply to offerings brought by non-Jews? A baraita is brought which states that the tzitz (forehead plate of the High Priest) does not atone for offerings brought by non-Jews. Does this baraita align with the opinion of Rabbi Yosi as well? The prohibition against eating notar (leftover sacrificial meat) and tamei (impure items) applies even to offerings that do not have elements permitting consumption. What is the source for these halakhot?
