Zevachim 69A

וליטעמיך, ״שלא היה פסולו בקודש״ לאיתויי מאי?

The Talmud responds: And according to your reasoning, one could infer the opposite from the following clause: The meat of any bird whose disqualification did not occur in the sacred Temple courtyard transmits ritual impurity to one who swallows it. Here, according to R' Yoḥanan, what disqualification is added if not pinching by a non-priest?

אלא רישא לאיתויי שחיטת קדשים בפנים, סיפא לאיתויי מליקת חולין בחוץ.

Rather, both clauses add other disqualifications not mentioned in the Mishnah. The former clause, concerning an offering that was disqualified in the Temple courtyard, is written to add that the slaughter of sacrificial birds inside the Temple courtyard does not render them carcasses. The latter clause, with regard to an offering disqualified outside the Temple courtyard, is written to add that the pinching of non-sacred birds outside the Temple courtyard does render them carcasses.

תניא כוותיה דרבי יוחנן: מלקה זר, מלקה פסול, הפיגול והנותר והטמא ⁠– אין מטמאין אבית הבליעה.

It is taught in a baraita in accordance with the opinion of R' Yoḥanan: In a case where a non-priest pinched a bird offering, or a priest disqualified from the Temple service pinched it, or it became piggul, i.e., it was sacrificed with the intent to consume it beyond its designated time, or it became notar, i.e., its meat remained uneaten beyond its designated time, or it became ritually impure, in all these cases, even though the meat of these birds may not be consumed, they still do not render one who swallows them ritually impure when they are in the throat.

אמר רבי יצחק: שמעתי שתים ⁠– אחת קמיצת זר, ואחת מליקת זר; אחת תרד, ואחת לא תרד; ולא ידענא. אמר חזקיה, מסתברא: קמיצה תרד, מליקה לא תרד.

R' Yitzḥak says: I heard [shamati] two halakhot, one concerning the removal of a handful from a meal offering by a non-priest for burning on the altar, and one concerning the pinching of a bird offering by a non-priest. Although both offerings are disqualified, I heard that one should descend from the altar if it ascended, and one should not descend; but I do not know which halakha applies to which case. Ḥizkiyya said: It stands to reason that in the case of the removal of the handful the offering should descend and in the case of pinching the offering should not descend.
