14שְׁתֵּי קֻפּוֹת אַחַת שֶׁל תְּרוּמָה וְאַחַת שֶׁל חֻלִּין וְנָפְלָה תְּרוּמָה לְתוֹךְ אַחַת מֵהֶן וְאֵין יָדוּעַ לְאֵי זוֹ נָפְלָה הֲרֵינִי אוֹמֵר לְתוֹךְ שֶׁל תְּרוּמָה נָפְלָה. אֵין יָדוּעַ אֵי זוֹ הִיא שֶׁל תְּרוּמָה אָכַל זָר אַחַת מֵהֶן הֲרֵי זֶה פָּטוּר מִן הַתַּשְׁלוּמִין שֶׁהַמּוֹצִיא מֵחֲבֵרוֹ עָלָיו הָרְאָיָה. וְהַשְּׁנִיָּה נוֹהֵג בָּהּ כִּתְרוּמָה. אָכַל אַחֵר אֶת הַשְּׁנִיָּה אַף הוּא פָּטוּר. אָכַל אֶחָד אֶת שְׁתֵּיהֶן מְשַׁלֵּם כַּקְּטַנָּה שֶׁבִּשְׁתֵּיהֶן. אִם מֵזִיד קֶרֶן. וְאִם שׁוֹגֵג קֶרֶן וְחֹמֶשׁ:
When there are two containers, one of terumah and one of ordinary produce, and terumah fell into one of them, but it is not known which one, we operate under the supposition that it fell into the one which [contained] terumah. If it is not known which one is terumah and a non-priest partakes of one of them, he is not liable for payment. [The rationale is that when a person seeks] to expropriate money from a colleague, the burden of proof is on him. He must treat the other one as if it were terumah. If another person partakes of the other one, however, he is also exempt. If, however, one person eats them both, he must make restitution for the smaller one. If he did so intentionally, he is required to make restitution for the principal. If he did so unknowingly, he is required to make restitution for the principal, plus a fifth.
