אהלות ז׳Oholot 7

Mishnah 1א׳

הַטֻּמְאָה בַכֹּתֶל, וּמְקוֹמָהּ טֶפַח עַל טֶפַח עַל רוּם טֶפַח, כָּל הָעֲלִיּוֹת שֶׁעַל גַּבָּהּ, אֲפִלּוּ הֵן עֶשֶׂר, טְמֵאוֹת. הָיְתָה עֲלִיָּה אַחַת עַל גַּבֵּי שְׁנֵי בָתִּים, הִיא טְמֵאָה, וְכָל הָעֲלִיּוֹת שֶׁעַל גַּבָּהּ, טְהוֹרוֹת. כֹּתֶל שָׁנִית, טֻמְאָה בוֹקַעַת וְעוֹלָה, בּוֹקַעַת וְיוֹרָדֶת. נֶפֶשׁ אֲטוּמָה, הַנּוֹגֵעַ בָּהּ מִן הַצְּדָדִין, טָהוֹר, מִפְּנֵי שֶׁטֻּמְאָה בוֹקַעַת וְעוֹלָה, בּוֹקַעַת וְיוֹרָדֶת. אִם הָיָה מְקוֹם הַטֻּמְאָה טֶפַח עַל טֶפַח עַל רוּם טֶפַח, הַנּוֹגֵעַ בָּהּ מִכָּל מָקוֹם, טָמֵא, מִפְּנֵי שֶׁהִיא כְקֶבֶר סָתוּם. סָמַךְ לָהּ סֻכּוֹת, טְמֵאוֹת. רַבִּי יְהוּדָה מְטַהֵר:

If there was impurity in the wall and its place was a handbreadth by a handbreadth by a handbreadth height, all upper stories that are above it, even if they were ten, are impure. If there was one upper story above two houses it is impure and all the upper stories that are above it are pure. A second wall, the impurity pierces and goes up, pierces and goes down. A solid gravestone, if one touches it from the sides he is pure because the impurity pierces and goes up, pierces and goes down. If the place of the impurity was a handbreadth by a handbreadth by a handbreadth height, one who touches it in any place is impure because it is like a sealed grave. If he supported booths with it, they are impure, but Rabbi Yehuda declares [them] pure.

Mishnah 2ב׳

כָּל שִׁפּוּעֵי אֹהָלִין, כָּאֹהָלִין. אֹהֶל שֶׁהוּא שׁוֹפֵעַ וְיוֹרֵד, וְכָלֶה עַד כְּאֶצְבַּע, טֻמְאָה בָאֹהֶל, כֵּלִים שֶׁתַּחַת הַשִּׁפּוּעַ, טְמֵאִים. טֻמְאָה תַחַת הַשִּׁפּוּעַ, כֵּלִים שֶׁבָּאֹהֶל, טְמֵאִין. טֻמְאָה מִתּוֹכוֹ, הַנּוֹגֵעַ בּוֹ מִתּוֹכוֹ, טָמֵא טֻמְאַת שִׁבְעָה. וּמֵאֲחוֹרָיו, טָמֵא טֻמְאַת עָרֶב. טֻמְאָה מֵאֲחוֹרָיו, הַנּוֹגֵעַ בּוֹ מֵאֲחוֹרָיו, טָמֵא טֻמְאַת שִׁבְעָה. מִתּוֹכוֹ, טָמֵא טֻמְאַת עָרֶב. כַּחֲצִי זַיִת מִתּוֹכוֹ וְכַחֲצִי זַיִת מֵאֲחוֹרָיו, הַנּוֹגֵעַ בּוֹ, בֵּין מִתּוֹכוֹ בֵּין מֵאֲחוֹרָיו, טָמֵא טֻמְאַת עָרֶב. מִקְצָתוֹ מְרֻדָּד עַל הָאָרֶץ, טֻמְאָה תַחְתָּיו אוֹ עַל גַּבָּיו, טֻמְאָה בוֹקַעַת וְעוֹלָה, בּוֹקַעַת וְיוֹרָדֶת. אֹהֶל שֶׁהוּא נָטוּי בָּעֲלִיָּה, מִקְצָתוֹ מְרֻדָּד עַל הָאֲרֻבָּה שֶׁבֵּין בַּיִת לָעֲלִיָּה, רַבִּי יוֹסֵי אוֹמֵר, מַצִּיל. רַבִּי שִׁמְעוֹן אוֹמֵר, אֵינוֹ מַצִּיל, עַד שֶׁיְּהֵא נָטוּי כִּנְטִיַּת הָאֹהֶל:

All sloping tents are like [other] tents. If the tent sloped downwards and ended less than a finger from the ground, if there was impurity in the tent, vessels underneath the slope are impure, if there was impurity under the slope vessels in the tent are impure. If there is impurity inside it, one who touches its inside is impure for seven days and [one who touches] its outside is impure until evening. If there is impurity outside it, one who touches its outside is impure for seven days and [one who touches] its inside is impure until evening. If there is [a piece the size of] half an olive inside and half an olive outside, one who touches it, whether he touches its inside or its outside, is impure until evening. If part of it is spread flat on the ground, if there is impurity underneath it or on top of it, the impurity pierces and goes up, pierces and goes down. A tent which is pitched in an upper story, and part of it is spread flat over the hatch that is between the house and the upper story, Rabbi Yossi says it protects [from spreading impurity], but Rabbi Shimon says it does not protect, until it is pitched like the pitching of a tent.
