משנה: אָמַר רִבִּי יְהוֹשֻׁעַ שָׁמַעְתִּי שֶׁתְּמוּרַת הַפֶּסַח קְרֵיבָה וּתְמוּרַת הַפֶּסַח אֵינָהּ קְרֵיבָה וְאֵין לִי לְפָרֵשׁ. אָמַר רִבִּי עֲקִיבָה אֲנִי אֲפָרֵשׁ. הַפֶּסַח שֶׁנִּמְצָא קוֹדֶם שְׁחִיטַת הַפֶּסַח יִרְעֶה עַד שֶׁיִּסְתָּאֵב. וְיִמָּכֵר וְיָבִיא בְּדָמָיו שְׁלָמִים וְכֵן תְּמוּרָתוֹ. לְאַחַר שְׁחִיטַת הַפֶּסַח. קָרֵב שְׁלָמִים. וְכֵן תְּמוּרָתוֹ:
MISHNAH: Rebbi Joshua said, I have heard that the substitute of a Pesaḥ is sacrificed and that the substitute of a Pesaḥ is not sacrificed, and I cannot explain it. Rebbi Aqiba said, I shall explain it. The Pesaḥ which is found before the time of slaughtering the Pesaḥ shall graze until it becomes unusable, then be sold, and for the money one shall bring well-being offerings; the same holds for its substitute. After the time of slaughtering the Pesaḥ, it shall be brought as well-being offering; the same holds for its substitute.
