Mishnah Parah 10:5: If one [who was sufficiently pure for chatat] was standing beyond the oven, and he stretched out his hand to a window and he took the jug and passed it over the oven, Rabbi Akiva considers it impure, and the Sages consider it pure. But one who is pure for chatat may stand on an oven with an empty vessel which is pure for chatat in his hand, or with water that had not [yet] been sanctified [and they will remain pure].

הָיָה עוֹמֵד חוּץ לַתַּנּוּר וּפָשַׁט יָדָיו לַחַלּוֹן וְנָטַל אֶת הַלָּגִין וְהֶעֱבִירוֹ עַל גַּבֵּי הַתַּנּוּר, רַבִּי עֲקִיבָא מְטַמֵּא, וַחֲכָמִים מְטַהֲרִין. אֲבָל עוֹמֵד הוּא הַטָּהוֹר לְחַטָּאת עַל גַּבֵּי תַנּוּר וּבְיָדוֹ כְּלִי רֵיקָן הַטָּהוֹר לְחַטָּאת, וּבְמַיִם שֶׁאֵין מְקֻדָּשִׁין:

Mishnah Parah 10:6: Jugs of chatat that touched jugs of sanctified property or of trumah [a portion of produce which must be given to a priest and must be kept ritually pure], [the jug] of chatat is [made] impure and that of the sanctified property or of trumah is pure. If [he holds] both of them in two hands [i.e. the chatat jug in one hand and one of the other types in the other], both of them [the jugs] are impure. If the two of them were [wrapped] in two pieces of paper [as he held them in each hand], they are both pure. If that of chatat were in paper and that of trumah was in his hand, they are both impure. If that of trumah was in paper and that of chatat was in his hand, both of them are pure; Rabbi Yehoshua says: "that of the chatat is impure." If they were placed on the ground and one touched them [both, simultaneously], that of the chatat is impure, and that of the sanctified property or of the trumah are pure. If he moved them [without touching them], Rabbi Yehoshua considers [them] impure, and the Sages consider [them] pure.
