Mishnah for Demai 5:10
עָצִיץ נָקוּב, הֲרֵי זֶה כָּאָרֶץ. תָּרַם מֵהָאָרֶץ עַל עָצִיץ נָקוּב, מֵעָצִיץ נָקוּב עַל הָאָרֶץ, תְּרוּמָתוֹ תְּרוּמָה. מִשֶּׁאֵינוֹ נָקוּב עַל הַנָּקוּב, תְּרוּמָה, וְיַחֲזֹר וְיִתְרֹם. מִן הַנָּקוּב עַל שֶׁאֵינוֹ נָקוּב, תְּרוּמָה, וְלֹא תֵאָכֵל עַד שֶׁיּוֹצִיא עָלֶיהָ תְּרוּמוֹת וּמַעַשְׂרוֹת:
A perforated pot is [considered] like land. [If one] took <i>Terumah</i> from [produce grown in] the earth for [produce grown in] a perforated pot, or from a perforated pot for the earth, his <i>Terumah</i> is [valid] <i>Terumah</i>. From a non-perforated pot for a perforated pot, [this is treated with the stringencies of valid] <i>Terumah</i> [but] one must return and retake the <i>Terumah</i> [in a valid manner]. From a perforated pot for a non-perforated pot is [valid] <i>Terumah</i>, and cannot be eaten until <i>Terumot</i> and <i>Ma'asrot</i> have been removed for it.
