Mishnah Tevul Yom 4:4: Regarding a bottle which is a tevul yom which was filled from a cask of [first] tithes which are tevel [produce from which terumah has not yet been taken], if one said, "Let this become terumah of the tithe once night falls," it thereby is terumah of the tithe [once night falls]. If one [then] said, "Let this [food] be for an eruv [an amount of food set aside in a designated place in order to merge separate domains for the purposes of carrying and traveling on Shabbat]," he has said nothing. If the cask was broken, the content of bottle remains in its state of tevel [i.e. as though the terumah of the tithe has not yet been taken]. If the bottle was broken, the content of the cask remains it its state of tevel.

לָגִין שֶׁהוּא טְבוּל יוֹם, וּמִלְאָהוּ מִן הֶחָבִית מַעֲשֵׂר טֶבֶל, אִם אָמַר, הֲרֵי זוֹ תְרוּמַת מַעֲשֵׂר מִשֶּׁתֶּחְשָׁךְ, הֲרֵי זוֹ תְּרוּמַת מַעֲשֵׂר. אִם אָמַר, הֲרֵי זֶה עֵרוּב, לֹא אָמַר כְּלוּם. נִשְׁבְּרָה הֶחָבִית, הַלָּגִין בְּטִבְלוֹ. נִשְׁבַּר הַלָּגִין, הֶחָבִית בְּטִבְלָהּ:

Mishnah Tevul Yom 4:5: Initially they would say: One may redeem [fruits of the second tithe] for the produce of an am ha'aretz [one who is lax in observing tithes and purity laws]. They then went back and said: also for his money [without fearing that the money may itself be of second-tithe products]. Initially they would say: One who is being taken out [for sentencing] in shackles, if he said, “Write a divorce document for my wife,” they may thereby write one and give it [to her]. They then went back and said: even one who sets out [on a sea voyage], or who departs in a caravan. Rabbi Shimon Shezuri says: even one who is dangerously ill.

בָּרִאשׁוֹנָה הָיוּ אוֹמְרִים, מְחַלְּלִין עַל פֵּרוֹת עַם הָאָרֶץ. חָזְרוּ לוֹמַר, אַף עַל מְעוֹתָיו. בָּרִאשׁוֹנָה הָיוּ אוֹמְרִים, הַיּוֹצֵא בַקּוֹלָר וְאָמַר, כִּתְבוּ גֵט לְאִשְׁתִּי, הֲרֵי אֵלּוּ יִכְתְּבוּ וְיִתְּנוּ. חָזְרוּ לוֹמַר, אַף הַמְפָרֵשׁ וְהַיּוֹצֵא בִשְׁיָרָא. רַבִּי שִׁמְעוֹן שְׁזוּרִי אוֹמֵר, אַף הַמְסֻכָּן:
