If the Passover was slaughtered for a different purpose on the Sabbath, he [the slaughterer] is liable to a sin-offering on its account. While all other sacrifices which he slaughtered as a Passover, if they are not eligible, he is culpable; while if they are eligible, R. Eliezer rules him liable to a sin-offering, while R. Joshua rules him not culpable, said R. Eliezer to him: if the Passover, which is permitted for its own purpose, yet when he changes its purpose he is culpable; then [other] sacrifices, which are forbidden [even] for their own purpose, if he changes their purpose is it not logical that he is culpable! R. Joshua answered him, not so. If you say [thus] of the Passover, [He is culpable] because he changed it for something that is forbidden; will you say [the same] of [other] sacrifices, where he changed them for something that is permitted? Said R. Eliezer to him, let the public sacrifices prove it, which are permitted for their own sake, yet he who slaughters [other sacrifices] in their name is culpable. R. Joshua answered him: not so. If you say [thus] of public sacrifices, [that is] because they have a limit; Will you say [the same] of the Passover, which has no limit? R. Meir said: He too who slaughters [other sacrifices] in the name of public sacrifice is not liable.         פסחים 6.5
הפסח ששחטו שלא לשמו בשבת, חייב עליו חטאת׃ ושאר כל הזבחים ששחטן לשם הפסח-- אם אינן ראויים, חייב; ואם ראויים הם-- רבי אליעזר מחייב חטאת, ורבי יהושוע פוטר׃ אמר רבי אליעזר, מה אם הפסח שהוא מותר לשמו, כששינה את שמו-- חייב; זבחים שהן אסורין לשמן, כששינה את שמן-- אינו דין שיהא חייב׃ אמר לו רבי יהושוע, לא, אם אמרת בפסח ששינהו לדבר אסור, תאמר בזבחים ששינן לדבר מותר׃ אמר לו רבי אליעזר, אימורי הציבור יוכיחו, שהן מותרין לשמן, והשוחט לשמן, חייב׃ אמר לו רבי יהושוע, לא, אם אמרת באימורי ציבור שיש להן קצבה, תאמר בפסח שאין לו קצבה׃ רבי מאיר אומר, אף השוחט לשם אימורי ציבור, פטור
If he slaughtered it for those who are not its eaters, or for those who were not registered, for Uncircumcised or for unclean [persons], he is culpable; [if he slaughtered it] for its eaters and for those who are not its eaters, for those who are registered for it and for those who are not registered for it, for circumcised and for Uncircumcised, for unclean and for clean [persons], he is not liable. If he slaughtered it, and it was found to possess a blemish, he is liable. If he slaughtered it and it was found terefah internally, he is not liable. If he slaughtered it, and [then] it became known that its owners had withdrawn their hands from it, or that they had died, or that they had become unclean, he is not culpable, because he slaughtered with permission.         פסחים 6.6
שחטו שלא לאוכליו ושלא למנוייו, לערלים ולטמאים-- חייב׃ לאוכליו ושלא לאוכליו, למנוייו ושלא למנוייו, למולים ולערלים, לטהורים ולטמאים-- פטור׃ שחטו, ונמצא בעל מום-- חייב; שחטו, ונמצא טריפה בסתר-- פטור׃ שחטו, ונודע שמשכו הבעלים את ידם, או שמתו או שנטמאו-- פטור, מפני ששחט ברשות
