אהלות ד׳Oholot 4

Mishnah 1א׳

מִגְדָּל שֶׁהוּא עוֹמֵד בָּאֲוִיר, טֻמְאָה בְתוֹכוֹ, כֵּלִים שֶׁבְּעָבְיוֹ טְהוֹרִים. טֻמְאָה בְעָבְיוֹ, כֵּלִים שֶׁבְּתוֹכוֹ טְהוֹרִים. רַבִּי יוֹסֵי אוֹמֵר, מֶחֱצָה לְמֶחֱצָה. הָיָה עוֹמֵד בְּתוֹךְ הַבַּיִת, טֻמְאָה בְתוֹכוֹ, הַבַּיִת טָמֵא. טֻמְאָה בַבַּיִת, מַה שֶּׁבְּתוֹכוֹ טָהוֹר, שֶׁדֶּרֶךְ הַטֻּמְאָה לָצֵאת וְאֵין דַּרְכָּהּ לְהִכָּנֵס. כֵּלִים שֶׁבֵּינוֹ לְבֵין הָאָרֶץ, שֶׁבֵּינוֹ לְבֵין הַכֹּתֶל, שֶׁבֵּינוֹ לְבֵין הַקּוֹרוֹת, אִם יֶשׁ שָׁם פּוֹתֵחַ טֶפַח, טְמֵאִין. וְאִם לָאו, טְהוֹרִין. טֻמְאָה שָׁם, הַבַּיִת טָמֵא:

A cupboard standing [outside] in the open air: If there is impurity within it, vessels in the thickness [of its walls] are pure. If there is impurity in its thickness, vessels inside [the cupboard] are pure. Rabbi Yose says: half and half. If it is standing inside a house: If there is impurity inside [the cupboard], the house is impure; If there is impurity in the house, that which is within [the cupboard] is pure, for the manner of impurity is to go out and its manner is not to go in. Vessels that are between [the cupboard] and the ground, or that are between it and the wall, or that are between it and the roof-beams: If there is a handbreadth's space there, they are impure. If not, they remain pure. If there is impurity there, the house becomes impure.

Mishnah 2ב׳

תֵּבַת הַמִּגְדָּל, יֶשׁ בָּהּ פּוֹתֵחַ טֶפַח וְאֵין בִּיצִיאָתָהּ פּוֹתֵחַ טֶפַח, טֻמְאָה בְתוֹכָהּ, הַבַּיִת טָמֵא. טֻמְאָה בַבַּיִת, מַה שֶּׁבְּתוֹכָהּ טָהוֹר, שֶׁדֶּרֶךְ הַטֻּמְאָה לָצֵאת וְאֵין דַּרְכָּהּ לְהִכָּנֵס. רַבִּי יוֹסֵי מְטַהֵר, מִפְּנֵי שֶׁהוּא יָכוֹל לְהוֹצִיאָהּ לַחֲצָאִים אוֹ לְשָׂרְפָהּ בִּמְקוֹמָהּ:

A drawer of a cupboard that has a handbreadth's space, but whose outlet does not have a handbreadth's space, if there is impurity inside it, the house becomes impure; if there is impurity in the house, that which is within [the drawer] is pure, for the manner of impurity is to go out and its manner is not to go in. Rabbi Yose declares [the house] pure, since he can remove [the impurity] in halves or burn it in its place.
