Reference for Tevul Yom 2:5
בְּשַׂר הַקֹּדֶשׁ שֶׁקָּרַם עָלָיו הַקִּפָּה, נָגַע טְבוּל יוֹם בַּקִּפָּה, חֲתִיכוֹת מֻתָּרוֹת. נָגַע בַּחֲתִיכָה, חֲתִיכָה וְכָל הָעוֹלִים עִמָּהּ, חִבּוּר זֶה לָזֶה. רַבִּי יוֹחָנָן בֶּן נוּרִי אוֹמֵר, שְׁנֵיהֶם חִבּוּר זֶה לָזֶה. וְכֵן בְּקִטְנִיּוֹת שֶׁקָּרְמוּ עַל גַּבֵּי פְרוּסוֹת. מַעֲשֵׂה קְדֵרָה בַקִּטְנִיּוֹת, בִּזְמַן שֶׁהֵן פְּרוּדִים, אֵינָן חִבּוּר. בִּזְמַן שֶׁהֵן גּוּשׁ, חִבּוּר. אִם הָיוּ גוּשִׁין הַרְבֵּה, הֲרֵי אֵלּוּ יִמָּנוּ. שֶׁמֶן שֶׁהוּא צָף עַל גַּבֵּי הַיַּיִן וְנָגַע טְבוּל יוֹם בַּשֶּׁמֶן, לֹא פָסַל אֶלָּא הַשֶּׁמֶן. רַבִּי יוֹחָנָן בֶּן נוּרִי אוֹמֵר, שְׁנֵיהֶם חִבּוּר זֶה לָזֶה:
Regarding sanctified meat over which a film [from the juices and seasonings] has congealed, if a <i>tevul yom</i> touched the film, the slices [of meat] are permitted [i.e. are not considered connected to the film]. If he touched a slice, the slice and all that comes with it are considered connected to one another. Rabbi Yochanan ben Nuri says: they both [i.e. in the first case as well] are considered connected to one another. And similarly regarding beans which have congealed over slices of bread. Regarding beans cooked in a pot, when they are separated, they are not considered connected [to each other]; when they are in a single mass, they are considered connected; and if there were several masses, they must be counted [i.e. the one that touched the source of impurity retains a primary degree of impurity, and the next mass to touch it retains a second degree impurity, and so on]. Regarding oil which floats on wine, if a <i>tevul yom</i> touched the oil, he has only invalidated the oil. Rabbi Yohanan ben Nuri says: they both are considered connected to one another.
