טבול יום א׳Tevul Yom 1

Mishnah 1א׳

הַמְכַנֵּס חַלּוֹת עַל מְנָת לְהַפְרִישׁ, וְנָשְׁכוּ, בֵּית שַׁמַּאי אוֹמְרִים, חִבּוּר בִּטְבוּל יוֹם. וּבֵית הִלֵּל אוֹמְרִים, אֵינוֹ חִבּוּר. מִקְרָצוֹת נוֹשְׁכוֹת זוֹ בָזוֹ, וְכִכָּרוֹת נוֹשְׁכוֹת זוֹ בָזוֹ, הָאוֹפֶה חֲמִיטָה עַל גַּבֵּי חֲמִיטָה עַד שֶׁלֹּא קָרְמוּ בַתַּנּוּר, וְקוֹלִית שֶׁל מַיִם הַמְחֻלְחֶלֶת, וּרְתִיחַת גְּרִיסִין שֶׁל פּוֹל רִאשׁוֹנָה, וּרְתִיחַת יַיִן חָדָשׁ, רַבִּי יְהוּדָה אוֹמֵר, אַף שֶׁל אֹרֶז, בֵּית שַׁמַּאי אוֹמְרִים, חִבּוּר בִּטְבוּל יוֹם. בֵּית הִלֵּל אוֹמְרִים, אֵינוֹ חִבּוּר. וּמוֹדִים בִּשְׁאָר כָּל הַטֻּמְאוֹת, בֵּין קַלּוֹת בֵּין חֲמוּרוֹת:

If one [i.e. a priest] gathered portions of challah [a portion of a batch of bread dough given to a Kohen which becomes holy upon separation, and can only be consumed by Kohanim or their household] with the intention of separating them, and they become stuck together, Beit Shammai say: this is [considered] a connection [for impurity if any part of them is touched] regarding a tevul yom [one who has immersed that day in a mikvah, but who must wait until nightfall to become fully pure, and is of a second degree impurity until then]. Beit Hillel says: it is not [considered] a connection. Regarding pieces of dough [of terumah] that have become stuck to one another, or loaves that have become stuck to one another, [or] if one bakes one flat batter-cake on top of another and they have not yet crusted over in the oven, or the froth on water that is bubbling, or the first froth that rises when boiling groats of beans, or the froth from boiling new wine, and Rabbi Yehuda says: also that of rice, Beit Shammai say: they are [considered] a connection [for impurity] with regard to a tevul yom; Beit Hillel say: they are not [considered] a connection. And they [both] concede regarding all other impurities, whether of minor or major degrees [that these are considered connections].

Mishnah 2ב׳

הַמְכַנֵּס חַלּוֹת עַל מְנָת שֶׁלֹּא לְהַפְרִישׁ, הָאוֹפֶה חֲמִיטָה עַל גַּבֵּי חֲמִיטָה מִשֶּׁקָּרְמוּ בַתַּנּוּר, וְקוֹלִית שֶׁל מַיִם שֶׁאֵינָהּ מְחֻלְחֶלֶת, וּרְתִיחַת גְּרִיסִין שֶׁל פּוֹל שְׁנִיָּה, וּרְתִיחַת יַיִן יָשָׁן, וְשֶׁל שֶׁמֶן לְעוֹלָם, וְשֶׁל עֲדָשִׁים, רַבִּי יְהוּדָה אוֹמֵר, אַף שֶׁל טֹפַח, טְמֵאִים בִּטְבוּל יוֹם, וְאֵין צָרִיךְ לוֹמַר בְּכָל הַטֻּמְאוֹת:

If one gathered portions of challah with the intention not to separate them, [or] if one bakes a flat batter-cake on top of another and they have crusted over in the oven, or the froth on water that is not bubbling, or the second froth that rises when boiling groats of beans, or the froth from boiling of old wine, or that of any oil, or of lentils, Rabbi Yehudah says: even of beans, [all of these] are rendered impure [if touched] by a tevul yom; and it is needless to say [that this is the case] regarding all other impurities.
