אִ֥ישׁ אִישׁ֙ מִבֵּ֣ית יִשְׂרָאֵ֔ל אֲשֶׁ֨ר יִשְׁחַ֜ט שׁ֥וֹר אוֹ־כֶ֛שֶׂב אוֹ־עֵ֖ז בַּֽמַּחֲנֶ֑ה א֚וֹ אֲשֶׁ֣ר יִשְׁחַ֔ט מִח֖וּץ לַֽמַּחֲנֶֽה׃
Qualquer homem dos Filhos de Yisrael que abater um boi, ou um cordeiro, ou uma cabra no acampamento, ou que abater fora do acampamento,
Mishnah Zevachim
If one nips a bird [offering] inside and offers it up outside, he is liable; If one nips it outside and offers it up outside, he is exempt. If one slaughters a bird inside and offers it up outside, he is exempt. If one slaughters [it] outside and offers [it] up outside, he is liable. Thus its prescribed rite inside exempts him [if he does it] outside, while its prescribed rite outside exempts him [if he does it] inside. Rabbi Shimon says: whatever he is liable for outside, he is liable in similar circumstances inside when one [subsequently] offers it up outside; except when one slaughters [a bird] inside and offers [it] up outside.
Mishnah Zevachim
When they came to Gilgal, bamot (local altars) were [again] permitted. Most holy sacrifices were eaten within the curtains, and less holy sacrifices [were eaten] anywhere.
