Reference for Keritot 4:3
רַבִּי שִׁמְעוֹן שְׁזוּרִי וְרַבִּי שִׁמְעוֹן אוֹמְרִים, לֹא נֶחְלְקוּ עַל דָּבָר שֶׁהוּא מִשּׁוּם שֵׁם אֶחָד, שֶׁהוּא חַיָּב. וְעַל מַה נֶּחְלְקוּ. עַל דָּבָר שֶׁהוּא מִשּׁוּם שְׁנֵי שֵׁמוֹת, שֶׁרַבִּי אֱלִיעֶזֶר מְחַיֵּב חַטָּאת וְרַבִּי יְהוֹשֻׁעַ פּוֹטֵר. אָמַר רַבִּי יְהוּדָה, אֲפִלּוּ נִתְכַּוֵּן לְלַקֵּט תְּאֵנִים וְלִקֵּט עֲנָבִים, עֲנָבִים וְלִקֵּט תְּאֵנִים, שְׁחוֹרוֹת וְלִקֵּט לְבָנוֹת, לְבָנוֹת וְלִקֵּט שְׁחוֹרוֹת, רַבִּי אֱלִיעֶזֶר מְחַיֵּב חַטָּאת, וְרַבִּי יְהוֹשֻׁעַ פּוֹטֵר. אָמַר רַבִּי יְהוּדָה, תָּמֵהַּ אֲנִי אִם יִפְטֹר בָּהּ רַבִּי יְהוֹשֻׁעַ. אִם כֵּן, לָמָּה נֶאֱמַר (ויקרא ד), אֲשֶׁר חָטָא בָּהּ. פְּרָט לְמִתְעַסֵּק:
Rabbi Shimon and Rabbi Shimon Shezuri say: They do not disagree regarding transgressions of the same type that an individual is liable. About what do they disagree? About transgressions of two different types: Rabbi Eliezer deems him liable for a <i>Chattat</i>, but Rabbi Yehoshua exempts [him]. Rabbi Yehudah said: Even if he intended to pick figs and he picked grapes, [or] grapes and he picked figs; [or he intended to pick] black [fruit] and he picked white ones; [or] white ones and he picked black ones, Rabbi Eliezer deems him liable for a <i>Chattat</i>, but Rabbi Yehoshua exempts [him]. Rabbi Yehudah said: I wonder whether Rabbi Yehoshua would exempt him [in such a case]. Why then is it written, “With which he has sinned” (Leviticus 4:23)? To exclude accidental action.
