תרומות ב׳Terumot 2

Mishnah 1א׳

אֵין תּוֹרְמִין מִטָּהוֹר עַל הַטָּמֵא. וְאִם תָּרְמוּ, תְּרוּמָתָן תְּרוּמָה. בֶּאֱמֶת אָמְרוּ, הָעִגּוּל שֶׁל דְּבֵלָה שֶׁנִּטְמָא מִקְצָתוֹ, תּוֹרֵם מִן הַטָּהוֹר שֶׁיֶּשׁ בּוֹ עַל הַטָּמֵא שֶׁיֶּשׁ בּוֹ. וְכֵן אֲגֻדָּה שֶׁל יָרָק, וְכֵן עֲרֵמָה. הָיוּ שְׁנֵי עִגּוּלִים, שְׁתֵּי אֲגֻדּוֹת, שְׁתֵּי עֲרֵמוֹת, אַחַת טְמֵאָה וְאַחַת טְהוֹרָה, לֹא יִתְרֹם מִזֶּה עַל זֶה. רַבִּי אֱלִיעֶזֶר אוֹמֵר, תּוֹרְמִין מִן הַטָּהוֹר עַל הַטָּמֵא:

One may not set aside Terumah [produce set aside for priestly consumption] from the pure for the impure. And if they set the Terumah aside, their Terumah is [valid] Terumah. Truly they said, the fig round, some of which has been made impure, one may set aside Terumah from the pure that is in it for the impure that is in it. And so too with a bundle of greenery, and so too with a pile. If there were two rounds, two bundles, or two piles--one impure and one pure--one may not set aside Terumah from one for the other. Rabbi Eliezer says: one may set aside Terumah from the pure for the impure.

Mishnah 2ב׳

אֵין תּוֹרְמִין מִן הַטָּמֵא עַל הַטָּהוֹר. וְאִם תָּרַם, שׁוֹגֵג, תְּרוּמָתוֹ תְּרוּמָה, וּמֵזִיד, לֹא עָשָׂה כְלוּם. וְכֵן בֶּן לֵוִי שֶׁהָיָה לוֹ מַעֲשֵׂר טֶבֶל, הָיָה מַפְרִישׁ עָלָיו וְהוֹלֵךְ, שׁוֹגֵג, מַה שֶׁעָשָׂה, עָשׂוּי, מֵזִיד, לֹא עָשָׂה כְלוּם. רַבִּי יְהוּדָה אוֹמֵר, אִם הָיָה יוֹדֵעַ בּוֹ בַּתְּחִלָּה, אַף עַל פִּי שֶׁהוּא שׁוֹגֵג, לֹא עָשָׂה כְלוּם:

One may not set aside Terumah from the impure for the pure. And if he accidentally set the Terumah aside, their Terumah is [valid] Terumah. If intentionally, [it is as if] he has done nothing. And so too with a Levite who had tithes from which Terumah had not been taken, and was continuously designating [parts of these impure tithes as the Terumah of other tithes]: if accidentally, what he did is done [with validity]. If intentionally, [it is as if] he has done nothing. Rabbi Yehudah said, if he knew that it was [impure] in the beginning, even if he [forgot and designated] accidentally, [it is as if] he has done nothing.
