Reference for Maaser Sheni 3:12
הַמַּשְׁאִיל קַנְקַנִּין לְמַעֲשֵׂר שֵׁנִי, אַף עַל פִּי שֶׁגָּפָן, לֹא קָנָה מַעֲשֵׂר. זָלַף לְתוֹכָן סְתָם, עַד שֶׁלֹּא גָפָן, לֹא קָנָה מַעֲשֵׂר. מִשֶּׁגָּפָן, קָנָה מַעֲשֵׂר. עַד שֶׁלֹּא גָפָן, עוֹלוֹת בְּאֶחָד וּמֵאָה, וּמִשֶּׁגָּפָן, מְקַדְּשׁוֹת בְּכָל שֶׁהֵן. עַד שֶׁלֹּא גָפָן, תּוֹרֵם מֵאַחַת עַל הַכֹּל, וּמִשֶּׁגָּפָן, תּוֹרֵם מִכָּל אַחַת וְאֶחָת:
One who lends his jugs for <i>Maaser Sheni</i> [wine], even though he sealed them [after pouring the wine into them], they did not acquire [the status of] <i>Ma'aser</i> [<i>Sheni</i>]. If one simply pours into them [without specifying that he is lending them], as long as he does not seal them, they did not acquire [the status of] <i>Ma'aser</i> [<i>Sheni</i>]. But from when they are sealed, they acquire [the status of] <i>Ma'aser</i> [<i>Sheni</i>]. As long as he does not seal them, they are nullified [if a jug of <i>Terumah</i> wine is lost] in one hundred and one [jugs]. But from when they are sealed, they can make any amount [of jugs] sacred. As long as he does not seal them, he can separate <i>Terumah</i> from one jug for all [the jugs]. But from when they are sealed, he must separate <i>Terumah</i> from each one on its own.
