משנה: הַפֶּסַח שֶׁשְּׁחָטוֹ שֶׁלֹּא לִשְׁמוֹ בַשַּׁבָּת חַיָיב עָלָיו חַטָּאת. וּשְׁאָר כָּל הַזְּבָחִים שֶׁשְּׁחָטָן לְשֵׁם פֶּסַח אִם אֵינָן רְאוּיִין חַיָיב. וְאִם רְאוּיִין הֵן רִבִּי אֱלִיעֶזֶר מְחַיֵיב חַטָּאת. וְרִבִּי יְהוֹשֻׁעַ פּוֹטֵר. אָמַר רִבִּי אֱלִיעֶזֶר מָה אִם הַפֶּסַח שֶׁהוּא מוּתָּר לִשְׁמוֹ כְּשֶׁשִּׁינָּה שְׁמוֹ חַיָיב. זְבָחִים שֶׁהֵן אֲסוּרִין לִשְׁמָן כְּשֶׁשִּׁינָּה אֶת שְׁמָן אֵינוֹ דִין שֶׁיְּהֵא חַיָיב. אָמַר לוֹ רִבִּי יְהוֹשֻׁעַ. לֹא. אִם אָמַרְתָּ בַּפֶּסַח שֶׁשִּׁינָּהוּ אֶת שְׁמוֹ בְדָבָר אָסוּר. תֹּאמַר בַּזְּבָחִים שֶׁשִּׁנָּן בְּדָבָר מוּתָּר. אָמַר לוֹ רִבִּי אֱלִיעֶזֶר. אֵימֻרֵי צִיבּוּר יוֹכִיחַ. שֶׁהֵן מוּתָּרִין לִשְׁמָן הַשּׁוֹחֵט לִשְׁמָן חַיָיב. אָמַר לוֹ רִבִּי יְהוֹשֻׁעַ. לֹא. אִם אָמַרְתָּ בְּאֵימֻרֵי צִיבּוּר שֶׁכֵּן יֵשׁ לָהֶן קִיצְבָה. תֹּאמַר בַּפֶּסַח שֶׁאֵין לוֹ קִצְבָה. רִבִּי מֵאִיר אוֹמֵר. אַף הַשּׁוֹחֵט לְשֵׁם אֵימוֹרֵי צִיבּוּר פָּטוּר:
MISHNAH: He who slaughters the Pesaḥ not for its purpose on the Sabbath is for this liable for a purification sacrifice. For any other sacrifice which he slaughtered for the purpose of Pesaḥ, if they are not suitable he is liable, if suitable, Rebbi Eliezer declares him liable for a purification sacrifice but Rebbi Joshua declares not liable. Rebbi Eliezer said to him, since for Pesaḥ, which is permitted for its purpose, he is liable if he changed its purpose, sacrifices which are forbidden for their purpose, it should be logical that he be liable if he changed their purpose. Rebbi Joshua answered him, no. If you argue about Pesaḥ, which he changed to something forbidden, what can you infer about sacrifices which he changed to something permitted? Rebbi Eliezer said to him, public parts should prove it, which are permitted for their purpose and he who slaughters for their purpose is liable. Rebbi Joshua answered him, no. If you argue about public parts which are fixed in number, what can you infer about Pesaḥ which is not fixed in number? Rebbi Meïr says, also he who slaughters for the purpose of public parts is not liable.
