Mishnah for Orlah 3:7
שֶׁהָיָה רַבִּי מֵאִיר אוֹמֵר, אֶת שֶׁדַּרְכּוֹ לִמָּנוֹת, מְקַדֵּשׁ. וַחֲכָמִים אוֹמְרִים, אֵינוֹ מְקַדֵּשׁ אֶלָּא שִׁשָּׁה דְבָרִים בִּלְבָד. וְרַבִּי עֲקִיבָא אוֹמֵר, שִׁבְעָה. וְאֵלּוּ הֵם, אֱגוֹזֵי פֶרֶךְ, רִמּוֹנֵי בָדָן, וְחָבִיּוֹת סְתוּמוֹת, וְחֻלְפוֹת תְּרָדִין, וְקֻלְסֵי כְרוּב, וּדְלַעַת יְוָנִית. רַבִּי עֲקִיבָא אוֹמֵר, אַף כִּכָּרוֹת שֶׁל בַּעַל הַבָּיִת. הָרָאוּי לְעָרְלָה, עָרְלָה. לְכִלְאֵי הַכֶּרֶם, כִּלְאֵי הַכָּרֶם:
As Rabbi Meir used to say, if it is the normal way to count [an object, individually], then it renders everything as holy [and thereby forbidden]. But the Sages say that only six things render everything as holy; while Rabbi Akiva says there are seven. They are: nuts with brittle shells, and Badan pomegranates, and sealed jars, and beet shoots, and cabbage heads, and Greek gourds. Rabbi Akiva says, also loaves of bread of homeowners. That which is fit for the [laws of] <i>Orlah</i> is <i>Orlah</i>. That which is fit for [the laws of] <i> Kilayim</i> of the vineyard is <i> Kilayim</i> of the vineyard.
