Mishnah 1א׳
חֲמִשָּׁה לֹא יִתְרֹמוּ, וְאִם תָּרְמוּ, אֵין תְּרוּמָתָן תְּרוּמָה. הַחֵרֵשׁ, וְהַשּׁוֹטֶה, וְהַקָּטָן, וְהַתּוֹרֵם אֶת שֶׁאֵינוֹ שֶׁלּוֹ. נָכְרִי שֶׁתָּרַם אֶת שֶׁל יִשְׂרָאֵל, אֲפִלּוּ בִרְשׁוּת, אֵין תְּרוּמָתוֹ תְרוּמָה:
Five [types of people] may not set aside Terumah [produce consecrated for priestly consumption], and if they did set aside Terumah, their Terumah is not [valid] Terumah: the deaf-mute, and the shoteh, and the minor, and one who sets aside Terumah from what does not belong to him. If a non-Jew who set aside Terumah from what belongs to a Jew even with permission, [the non-Jew's] Terumah is not [valid] Terumah.
Mishnah 2ב׳
חֵרֵשׁ הַמְדַבֵּר וְאֵינוֹ שׁוֹמֵעַ, לֹא יִתְרֹם. וְאִם תָּרַם, תְּרוּמָתוֹ תְרוּמָה. חֵרֵשׁ שֶׁדִּבְּרוּ בוֹ חֲכָמִים בְּכָל מָקוֹם, שֶׁאֵינוֹ לֹא שׁוֹמֵעַ וְלֹא מְדַבֵּר:
A deaf person who can speak but cannot hear may not set aside Terumah. But if one did set aside Terumah, one's Terumah is valid Terumah. A deaf person that the Sages refer to in all cases can neither hear nor speak.
