Mishnah 1א׳

הַבֶּגֶד מִטַּמֵּא מִשּׁוּם חֲמִשָּׁה שֵׁמוֹת. הַשַּׂק, מִשּׁוּם אַרְבָּעָה. הָעוֹר, מִשּׁוּם שְׁלֹשָׁה. הָעֵץ, מִשּׁוּם שְׁנַיִם. וּכְלִי חֶרֶס, מִשּׁוּם אֶחָד. כְּלִי חֶרֶס מִטַּמֵּא מִשּׁוּם כְּלִי קִבּוּל. כֹּל שֶׁאֵין לוֹ תוֹךְ בִּכְלֵי חֶרֶס, אֵין לוֹ אֲחוֹרָיִם. מוּסָף עָלָיו הָעֵץ, שֶׁהוּא מִטַּמֵּא מִשּׁוּם מוֹשָׁב. וְכֵן טַבְלָא שֶׁאֵין לָהּ לִזְבֵּז, בִּכְלֵי עֵץ, טְמֵאָה, וּבִכְלֵי חֶרֶס, טְהוֹרָה. מוּסָף עָלָיו הָעוֹר, שֶׁהוּא מִטַּמֵּא מִשּׁוּם אֹהָלִים. מוּסָף עָלָיו הַשַּׂק, שֶׁהוּא מִטַּמֵּא מִשּׁוּם אָרִיג. מוּסָף עָלָיו הַבֶּגֶד, שֶׁהוּא מִטַּמֵּא מִשּׁוּם שָׁלֹשׁ עַל שָׁלֹשׁ:

Clothing may be rendered impure due to five different reasons; sack-cloth [may be rentered impure] due to four; leather due to three; wood due to two; and an earthenware vessel due to one. An earthenware vessel may be rendered impure [only] due to [being] a receptacle. Regarding earthenware vessels, any that has no inside, has no outside [which can be rendered impure]. Wood, in addition to this, can also be rendered impure due to [being] a seat. Similarly, regarding a tablet which has no rim, if it is a wooden vessel it is [susceptible to being rendered] impure; and if it is an earthenware vessel it is pure. Leather, in addition to this, may be rendered impure due to tents [if it forms an enclosure over certain impure things]. Sack-cloth, in addition to this, may be rendered impure due to [being] a woven work. Clothing, in addition to this, may be rendered impure due to [being] a three by three [fingerbreadths piece of fabric].

Mishnah 2ב׳

הַבֶּגֶד מִטַּמֵּא מִשּׁוּם שְׁלֹשָׁה עַל שְׁלֹשָׁה, לְמִדְרָס, וּמִשּׁוּם שָׁלֹשׁ עַל שָׁלֹשׁ לִטְמֵא מֵת. הַשַּׂק אַרְבָּעָה עַל אַרְבָּעָה, הָעוֹר חֲמִשָּׁה עַל חֲמִשָּׁה, מַפָּץ שִׁשָּׁה עַל שִׁשָּׁה, שָׁוִין לְמִדְרָס וְלִטְמֵא מֵת. רַבִּי מֵאִיר אוֹמֵר, הַשַּׂק שְׁיָרָיו אַרְבָּעָה, וּתְחִלָּתוֹ מִשֶּׁיִּגָּמֵר:

Clothing may be rendered impure as a [piece which is] three by three [handbreadths] with midras impurity [a type of impurity due to being sat on by certain impure individuals, rendering something an Origin of impurity], and at three by three [fingerbreadths] with corpse impurity. Sack-cloth [may be rendered impure] at four by four [handbreadths]; Leather, five by five; matting, six by six; these are all equally [susceptible to being rendered impure] with midras and corpse impurity. Rabbi Meir says: regarding sack-cloth, its scraps [may be rendered impure] at four [by four handbreadths], but initially [it can be rendered impure only] once it is completed.
