הלכות טומאת מת ו׳Defilement by a Corpse 6

Halacha 1א׳

עַצְמוֹת הַדָּג וְעוֹרוֹ הָעוֹשֶׂה מֵהֶן כֵּלִים אֵינָן מְקַבְּלִין טֻמְאָה כְּלָל לֹא מִדִּבְרֵי תּוֹרָה וְלֹא מִדִּבְרֵי סוֹפְרִים. וְכֵן יְרוֹקָה שֶׁעַל פְּנֵי הַמַּיִם וְכַיּוֹצֵא בָּהּ שֶׁכָּל מַה שֶּׁבַּיָּם טָהוֹר כְּמוֹ שֶׁיִּתְבָּאֵר בְּהִלְכוֹת כֵּלִים. לְפִיכָךְ הָעוֹשֶׂה אֹהֶל מֵעוֹר הַדָּג אוֹ מִצֶּמֶר שֶׁגָּדֵל בַּיָּם. אֵין עַצְמוֹ שֶׁל אֹהֶל זֶה מְקַבֵּל טֻמְאָה אַף עַל פִּי שֶׁמֵּבִיא אֶת הַטֻּמְאָה לְכָל אֲשֶׁר יִהְיֶה תַּחְתָּיו כִּשְׁאָר אֹהָלִים:

The bones of a fish and its skin, from which one makes vessels, do not receive impurity at all, neither by the words of the Torah nor by the words of the Scribes. So too the green growth upon the face of the water and the like; for everything that is in the sea is pure, as will be explained in the Laws of Vessels. Therefore one who makes a tent of a fish's skin, or of wool that grows in the sea — the substance of this tent does not receive impurity, even though it brings the impurity upon all that is beneath it, like the other tents.

Halacha 2ב׳

כְּלֵי גְּלָלִים וּכְלֵי אֲבָנִים וּכְלֵי אֲדָמָה אֵינָן מְקַבְּלִין טֻמְאָה לֹא מִדִּבְרֵי תּוֹרָה וְלֹא מִדִּבְרֵי סוֹפְרִים בֵּין טֻמְאַת מֵת בֵּין שְׁאָר הַטֻּמְאוֹת. וְכֵן כְּלִי עֵץ הֶעָשׂוּי לְנַחַת כְּגוֹן הַתֵּבָה וְהַמִּגְדָּל וְהַכַּוֶּרֶת שֶׁהֵן מַחֲזִיקִין אַרְבָּעִים סְאָה בְּלַח וְיִהְיֶה לָהֶם שׁוּלַיִם אֵינָן מְקַבְּלִין טֻמְאָה כְּלָל לֹא מִדִּבְרֵי תּוֹרָה וְלֹא מִדִּבְרֵי סוֹפְרִים. וְאֵלּוּ הֵן הַנִּקְרָאִין כְּלִי עֵץ הַבָּא בְּמִדָּה:

Vessels of dung, vessels of stone and vessels of earth do not receive impurity, neither by the words of the Torah nor by the words of the Scribes, whether corpse-impurity or the other impurities. So too wooden vessels made to remain in place, such as a chest, a cupboard and a beehive, which hold forty se'ah of liquid and have a bottom, do not receive impurity at all, neither by the words of the Torah nor by the words of the Scribes; and these are what are called wooden vessels of large capacity.

Halacha 3ג׳

כְּלֵי עֵץ פְּשׁוּטֵיהֶם טְהוֹרִים מְקַבְּלֵיהֶם טְמֵאִים. כְּלֵי חֶרֶשׂ פְּשׁוּטֵיהֶן טְהוֹרִין וּמְקַבְּלֵיהֶן טְמֵאִין וְאֵינָן טְמֵאִין אֶלָּא מֵאֲוִירָן אוֹ בְּהֶסֵּט הַזָּב. אֲפִלּוּ נָגַע כְּלִי חֶרֶשׂ בְּמֵת מִגַּבּוֹ אֵינוֹ מִתְטַמֵּא. וְאִם נִכְנְסָה טֻמְאָה מִן הַטֻּמְאוֹת בַּאֲוִירוֹ וְאַף עַל פִּי שֶׁלֹּא נָגְעָה בּוֹ נִטְמָא. הָיָה כְּלִי חֶרֶשׂ עִם הַמֵּת בְּאֹהֶל נִטְמָא שֶׁהֲרֵי הַטֻּמְאָה נִכְנְסָה בַּאֲוִירוֹ. וְאִם הָיָה מֻקָּף צָמִיד פָּתִיל הוּא וּמַה שֶּׁבְּתוֹכוֹ טָהוֹר כְּמוֹ שֶׁנִּתְפָּרֵשׁ בַּתּוֹרָה. שֶׁאֵין טֻמְאָה נִכְנְסָה לוֹ אֶלָּא מִפִּתְחוֹ וּבְהֶסֵּט הַזָּב. שֶׁהֲרֵי הוּא כְּמִי שֶׁנָּגַע בְּכֻלּוֹ:

As for wooden vessels, the flat ones among them are pure and those that hold something are impure. As for earthenware vessels, the flat ones among them are pure and those that hold something are impure; and they become impure only through their airspace, or by the shifting of a man with a flux. Even if an earthenware vessel touched a corpse on its outer side, it does not become impure; and if one of the impurities entered its airspace, even though it did not touch it, it has become impure. If an earthenware vessel was with a corpse under a tent, it has become impure, since the impurity entered its airspace. And if it was closed with a tightly sealed cover, it and what is within it are pure, as is set out explicitly in the Torah; for no impurity enters it except through its opening, and by the shifting of a man with a flux, since that is as though he had touched the whole of it.
