Mishnah 1א׳
הֵעִיד רַבִּי יְהוֹשֻׁעַ וְרַבִּי צָדוֹק עַל פִּדְיוֹן פֶּטֶר חֲמוֹר שֶׁמֵּת, שֶׁאֵין בּוֹ לַכֹּהֵן כְּלוּם, שֶׁרַבִּי אֱלִיעֶזֶר אוֹמֵר, חַיָּבִין בְּאַחֲרָיוּתָן כְּחָמֵשׁ סְלָעִים שֶׁל בֵּן. וַחֲכָמִים אוֹמְרִים, אֵין חַיָּבִין בְּאַחֲרָיוּתָן אֶלָּא כְפִדְיוֹן שֶׁל מַעֲשֵׂר שֵׁנִי:
Rabbi Yehoshua and Rabbi Tzadok testified about the redemption [sheep] of the first-born donkey, that if it had died, it is no longer the priests at all. But Rabbi Eliezer said that he is obligated in his responsibility [to give the priest the sheep], like [his obligation regarding] the five selaim [silver coins] [with which he redeems] his [first-born] son. The Sages say: He is only obligated in his responsibility in the same way [that he would be obligated] in the redemption of second tithes.
Mishnah 2ב׳
הֵעִיד רַבִּי צָדוֹק עַל צִיר חֲגָבִים טְמֵאִים, שֶׁהוּא טָהוֹר. שֶׁמִּשְׁנָה רִאשׁוֹנָה, חֲגָבִים טְמֵאִים שֶׁנִּכְבְּשׁוּ עִם חֲגָבִים טְהוֹרִים, לֹא פָסְלוּ צִירָן:
Rabbi Tzadok testified about the brine of impure locusts, that it is pure. But the first [i.e. earlier] Mishnah stated: If impure locusts were pickled along with pure locusts, their brine is not invalidated [for drinking].
