Zevachim 111B

שחט בחוץ והעלה בחוץ ⁠– חייב.

But if one slaughtered a bird offering outside the courtyard and then offered it up outside, he is liable.

נמצא דרך הכשירו בפנים ⁠– פטורו בחוץ, דרך הכשירו מבחוץ ⁠– פטורו בפנים.

Evidently, the manner of its preparation inside the courtyard, i.e., pinching, effects its exemption outside the courtyard, and the manner of its preparation outside the courtyard, i.e., slaughter, effects its exemption inside the courtyard.

רבי שמעון אומר: כל שחייבין עליו בחוץ ⁠– חייבין על כיוצא בו בפנים שהעלה בחוץ; חוץ מן השוחט בפנים ומעלה בחוץ.

R' Shimon says: With regard to any act of killing an animal concerning which, when it was performed outside the courtyard, one is liable for subsequently offering it up outside the courtyard, one is also liable for having offered the animal up outside the courtyard after performing a similar act of killing inside the courtyard. This is the halakha except with regard to one who slaughters a bird inside the courtyard and offers it up outside the courtyard; he is exempt.

גמ׳ האי ״הכשירו״?! חיובו הוא! תני ״חיובו״.

Talmud: In summarizing its rulings the Mishnah states: The manner of its preparation outside the courtyard effects its exemption inside the courtyard. The Talmud comments: This term: The manner of its preparation, is inappropriate when referring to the slaughter of a bird offering, as a bird offering is not prepared by slaughtering; on the contrary, it is disqualified if slaughtered. The slaughter of a bird offering outside the courtyard is the reason for its liability. The Talmud concedes: Emend the Mishnah and teach: Its liability.

רבי שמעון אומר [וכו׳]. אהיכא קאי?

§ The Mishnah cites the ruling of R' Shimon: R' Shimon says: With regard to any act of killing an animal concerning which, when it was performed outside the courtyard, one is liable for subsequently offering it up outside the courtyard, one is also liable for having offered the animal up outside the courtyard after performing a similar act of killing inside the courtyard. This is the halakha except with regard to one who slaughters a bird inside the courtyard and offers it up outside the courtyard; he is exempt. The Talmud asks: To what does he refer?
