הַבַּדָּדִין וְהַבּוֹצְרִין, כֵּיוָן שֶׁהִכְנִיסָן לִרְשׁוּת הַמְּעָרָה, דַּיּוֹ, דִּבְרֵי רַבִּי מֵאִיר. רַבִּי יוֹסֵי אוֹמֵר, צָרִיךְ לַעֲמֹד עֲלֵיהֶן עַד שֶׁיִּטְבֹּלוּ. רַבִּי שִׁמְעוֹן אוֹמֵר, אִם טְהוֹרִין לָהֶן, צָרִיךְ לַעֲמֹד עֲלֵיהֶם עַד שֶׁיִּטְבֹּלוּ. אִם טְמֵאִים לָהֶן, אֵינוֹ צָרִיךְ לַעֲמֹד עֲלֵיהֶם עַד שֶׁיִּטְבֹּלוּ:
Regarding olive press workers and olive harvesters, once he [the owner of the olive press] brings them into the area of the cave [containing a <i>mikvah</i> for ritual immersion], that is sufficient [for him to assume that they immersed themselves and their vessels, and are all pure], according to Rabbi Meir. Rabbi Yose says: he must stand over them until they immerse. Rabbi Shimon says: if they consider them [themselves and the vessels requiring immersion] to be pure, he must stand over them until they immerse; but if they consider them impure, he does not have to stand over them until they immerse.
Jerusalem Talmud Chagigah
Rebbi Jeremiah was of the opinion, only heave prepared in the purity of sancta. Therefore not in its own. Rebbi Yose said, even if prepared in its own. A Mishnah disagrees with Rebbi Yose: “He has to watch them until they immersed themselves.” Explain it: not in the time of the olive harvest. Could you say not in the time of the grape harvest? Rebbi Isaac ben Rebbi Eleazar said, if food prepared in purity touched it before three people used it, at the time of olive and grape harvests the food prepared in purity remains pure, not at the time of olive and grape harvests the food prepared in purity becomes impure. Does there exist any clay vessel which is pure and then makes impure? Are not all these of the same kind? But it must be the following: if food prepared in purity touched it before the time of olive and grape harvests the food prepared in purity remains pure. Does there exist any clay vessel which is impure and then pure? Are not all these of the same kind? But it must be the following: if food prepared in purity touched it when it was full the food prepared in purity remains pure. If he cleared it, the food prepared in purity becomes impure. Does there exist any clay vessel which is pure and then makes impure? Are not all these of the same kind? But it must be the following: if food prepared in purity touched it when it was empty the food prepared in purity becomes impure. If he filled it, the food prepared in purity remains pure. Does there exist any clay vessel which is pure and then makes impure? Are not all these of the same kind?
