אהלות ט׳Oholot 9

Mishnah 3ג׳

בַּמֶּה דְבָרִים אֲמוּרִים, בִּזְמַן שֶׁהִיא כְלִי מְחֻלְחָלֶת. הָיְתָה פְחוּתָה וּפְקוּקָה בְקַשׁ אוֹ אֲפוּצָה, אֵיזוֹ הִיא אֲפוּצָה, כֹּל שֶׁאֵין לָהּ טֶפַח מִמָּקוֹם אֶחָד, כַּזַּיִת מִן הַמֵּת נָתוּן תַּחְתֶּיהָ, כְּנֶגְדּוֹ עַד הַתְּהוֹם טָמֵא. עַל גַּבָּהּ, כְּנֶגְדּוֹ עַד הָרָקִיעַ טָמֵא. בַּבַּיִת, אֵין טָמֵא אֶלָּא הַבַּיִת. בְּתוֹכָהּ, אֵין טָמֵא אֶלָּא תוֹכָהּ:

When does this case apply? When it is a hollow vessel. If it was broken and plugged with straw or if it was pressed - what is considered pressed? Anything that does not have a hand-breadth from another place - if a [piece the size of] an olive is placed beneath it, opposite it down to the depths is impure. If on top of it, opposite it up to the firmament is impure. If [it is] in the house only the house is impure, if [it is] inside it only inside it is impure.

Mishnah 4ד׳

הָיְתָה גְבוֹהָה מִן הָאָרֶץ טֶפַח, טֻמְאָה תַחְתֶּיהָ אוֹ בַבַּיִת, תַּחְתֶּיהָ וְהַבַּיִת טָמֵא, תּוֹכָהּ וְגַבָּהּ טָהוֹר. בְּתוֹכָהּ, אֵין טָמֵא אֶלָּא תוֹכָהּ. עַל גַּבָּהּ, כְּנֶגְדּוֹ עַד הָרָקִיעַ טָמֵא:

If it [the basket] was a hand-breadth above the ground and there was impurity beneath it or in the house, beneath it and the house is impure, but its inside and on top of it is pure. [If it was] inside it, only its inside is impure. [If it was] on top of it, opposite it up to the firmament is impure.
