Mishnayos Zevachim Perek 13 Mishnah 7

מלק בחוץ – it is an un-slaughtered animal carcass, for there is no pinching of the head other than inside [the Temple courtyard], therefore he exempt on his offering/bringing it up on the altar outside, and if you should say, but aren’t all that are offered up outside are disqualified through their being taken outside, and similar a person who performs a ritual slaughter outside [of the Temple courtyard] is invalid and they are liable on its being offered on the altar, there the All-Merciful includes it but regarding the matter of the rest of invalid things, we require that it is accepted inside.

שחט בחוץ והעלה בחוץ חייב – even on the bringing up/offering on the altar. For all who are liable on its ritual slaughter outside [of the Temple courtyard] if he went back in and he or someone else brought them up/offered them, he is liable [on the ritual slaughter and on offering it up].

נמצא דרך הכשרו בפנים – In the Gemara it states (i.e., Tractate Zevakhim 111b, that it teaches that the manner of his liability by performing it inside [i.e., the Temple courtyard] exempts him outside [the Temple courtyard], and the manner of his liability by performing it outside, exempts him inside [the Temple courtyard. As for example, if he slaughtered the bird/fowl inside [the Temple courtyard] and offered it up outside [the Temple courtyard], he is exempt. If he slaughtered it outside [the Temple courtyard] and offered it up outside [the Temple courtyard], he is liable. If he pinched the head [of the bird] inside [the Temple courtyard] and offered it up outside, he is liable. If he pinched the head [of the bird] outside [the Temple courtyard] and offered it up inside [the Temple courtyard], he is exempt. It is found, that the place where he is made liable on his offering it up, if the first Divine service was performed in side, as for example with the pinching of the head that was done inside [the Temple courtyard], he is exempt for his offering it up, if the pinching of the head was done outside [the Temple courtyard]. But a person who becomes liable on his offering up, if the first Divine service was performed outside, like with the ritual slaughtering, he is exempted inside, if the animal was slaughtered inside and offered up outside.

רבי שמעון אומר כו' – the matter of the first Tanna/teacher is deficient and should be read as follows: And similarly, a person who slaughters an animal at night inside [the Temple courtyard] and offers it up outside [the Temple courtyard] is exempt, that it is not accepted inside, as it is written (Leviticus 19:6): “It shall be eaten on the day you sacrifice/ביום זבחכם,” but not at night, and it is found that the animal offering is invalid, and therefore he is not liable for his offering it up But if he did not slaughter outside [the Temple courtyard] at night but offered it up outside at night, he is liable, because since the ritual slaughter was at night outside the Temple courtyard, it was kosher/fit, therefore, he is liable for two things – on the ritual slaughter and on the offering up. But Rabbi Shimon disputes this and states: “Any act for which they are liable [when it is done] outside, for the like act are they liable [when it is done] inside and when one offered it up outside, except for him who slaughters inside and offers up [the bird offering] outside.” כל שחייבין עליו בחוץ חייבין על כיוצא בו בפנים שהעלהו בחוץ – that is to say, just as when the person who performs the ritual slaughter outside at night and the one who offers it up outside is liable, so also if he performed the ritual slaughter inside at night and offered it up outside, he is liable for the offering up [of the sacrifice], except for one who slaughters the bird/fowl inside and offered it up outside [the Temple courtyard] that he is exempt even though that if he performed the ritual slaughter and offered it up outside [the Temple courtyard], he is liable. But the Halakha is not according to Rabbi Shimon.
