אֲבוֹת הַטֻּמְאוֹת, הַשֶּׁרֶץ, וְשִׁכְבַת זֶרַע, וּטְמֵא מֵת, וְהַמְּצֹרָע בִּימֵי סָפְרוֹ, וּמֵי חַטָּאת שֶׁאֵין בָּהֶם כְּדֵי הַזָּיָה, הֲרֵי אֵלּוּ מְטַמְּאִין אָדָם וְכֵלִים בְּמַגָּע, וּכְלֵי חֶרֶשׂ בַּאֲוִיר, וְאֵינָם מְטַמְּאִין בְּמַשָּׂא:

The fathers of impurity are a: sheretz, semen, [an Israelite] who has contracted corpse impurity, a metzora during the days of his counting, and the waters of purification whose quantity is less than the minimum needed for sprinkling. Behold, these convey impurity to people and vessels by contact and to earthenware by presence within their airspace, But they do not convey impurity by being carried.

לְמַעְלָה מֵהֶם, נְבֵלָה, וּמֵי חַטָּאת שֶׁיֶּשׁ בָּהֶם כְּדֵי הַזָּיָה, שֶׁהֵם מְטַמְּאִין אֶת הָאָדָם בְּמַשָּׂא לְטַמֵּא בְגָדִים בְּמַגָּע, וַחֲשׂוּכֵי בְגָדִים בְּמַגָּע:

Above them are nevelah and waters of purification whose quantity is sufficient to be sprinkled, for these convey impurity to a person [even] by being carried so that he in turn conveys impurity to clothing by contact. Clothing, however, is free from impurity where there was contact alone.

לְמַעְלָה מֵהֶן, בּוֹעֵל נִדָּה, שֶׁהוּא מְטַמֵּא מִשְׁכָּב תַּחְתּוֹן כָּעֶלְיוֹן. לְמַעְלָה מֵהֶן, זוֹבוֹ שֶׁל זָב וְרֻקּוֹ וְשִׁכְבַת זַרְעוֹ וּמֵימֵי רַגְלָיו, וְדַם הַנִּדָּה, שֶׁהֵן מְטַמְּאִין בְּמַגָּע וּבְמַשָּׂא. לְמַעְלָה מֵהֶן, מֶרְכָּב, שֶׁהוּא מְטַמֵּא תַּחַת אֶבֶן מְסָמָא. לְמַעְלָה מִן הַמֶּרְכָּב, מִשְׁכָּב, שֶׁשָּׁוֶה מַגָּעוֹ לְמַשָּׂאוֹ. לְמַעְלָה מִן הַמִּשְׁכָּב, הַזָּב, שֶׁהַזָּב עוֹשֶׂה מִשְׁכָּב, וְאֵין מִשְׁכָּב עוֹשֶׂה מִשְׁכָּב:

Above them is one who had intercourse with a menstruant, for he defiles the bottom [bedding] upon which he lies as he does the top [bedding]. Above them is the issue of a zav, his spit, his semen and his urine, and the blood of a menstruant, for they convey impurity both by contact and by carrying. Above them is an object on which one can ride, for it conveys impurity even when it lies under a heavy stone. Above the object on which one can ride is that on which one can lie, for contact is the same as its carrying. Above the object on which one can lie is the zav, for a zav conveys impurity to the object on which he lies, while the object on which he lies cannot convey the same impurity to that upon which it lies.

לְמַעְלָה מִן הַזָּב, זָבָה, שֶׁהִיא מְטַמְּאָה אֶת בּוֹעֲלָהּ. לְמַעְלָה מִן הַזָּבָה, מְצֹרָע, שֶׁהוּא מְטַמֵּא בְּבִיאָה. לְמַעְלָה מִן הַמְּצֹרָע, עֶצֶם כַּשְּׂעֹרָה, שֶׁהוּא מְטַמֵּא טֻמְאַת שִׁבְעָה. חָמוּר מִכֻּלָּם, הַמֵּת, שֶׁהוּא מְטַמֵּא בְאֹהֶל, מַה שֶּׁאֵין כֻּלָּם מְטַמְּאִין:

Above the zav is the zavah, for she conveys impurity to the man who has intercourse with her. Above the zavah is the metzora, for he conveys impurity by entering into a house. Above the metzora is a [human] bone the size of a barley grain, for it conveys impurity for seven days. More strict than all these is a corpse, for it conveys impurity by ohel (tent) whereby all the others convey no impurity.

עֶשֶׂר טֻמְאוֹת פּוֹרְשׁוֹת מִן הָאָדָם. מְחֻסַּר כִּפּוּרִים, אָסוּר בַּקֹּדֶשׁ וּמֻתָּר בַּתְּרוּמָה וּבַמַּעֲשֵׂר. חָזַר לִהְיוֹת טְבוּל יוֹם, אָסוּר בַּקֹּדֶשׁ וּבַתְּרוּמָה וּמֻתָּר בַּמַּעֲשֵׂר. חָזַר לִהְיוֹת בַּעַל קֶרִי, אָסוּר בִּשְׁלָשְׁתָּן. חָזַר לִהְיוֹת בּוֹעֵל נִדָּה, מְטַמֵּא מִשְׁכָּב תַּחְתּוֹן כָּעֶלְיוֹן. חָזַר לִהְיוֹת זָב שֶׁרָאָה שְׁתֵּי רְאִיּוֹת, מְטַמֵּא מִשְׁכָּב וּמוֹשָׁב, וְצָרִיךְ בִּיאַת מַיִם חַיִּים, וּפָטוּר מִן הַקָּרְבָּן. רָאָה שָׁלֹשׁ, חַיָּב בַּקָּרְבָּן. חָזַר לִהְיוֹת מְצֹרָע מֻסְגָּר, מְטַמֵּא בְּבִיאָה, וּפָטוּר מִן הַפְּרִיעָה וּמִן הַפְּרִימָה וּמִן הַתִּגְלַחַת וּמִן הַצִּפֳּרִים. וְאִם הָיָה מֻחְלָט, חַיָּב בְּכֻלָּן. פֵּרַשׁ מִמֶּנּוּ אֵבָר שֶׁאֵין עָלָיו בָּשָׂר כָּרָאוּי, מְטַמֵּא בְמַגָּע וּבְמַשָּׂא, וְאֵינוֹ מְטַמֵּא בְאֹהֶל. וְאִם יֵשׁ עָלָיו בָּשָׂר כָּרָאוּי, מְטַמֵּא בְמַגָּע וּבְמַשָּׂא וּבְאֹהֶל. שִׁעוּר בָּשָׂר כָּרָאוּי, כְּדֵי לְהַעֲלוֹת אֲרוּכָה. רַבִּי יְהוּדָה אוֹמֵר, אִם יֵשׁ בְּמָקוֹם אֶחָד כְּדֵי לְהַקִּיפוֹ בְחוּט עֵרֶב, יֶשׁ בּוֹ לְהַעֲלוֹת אֲרוּכָה:

There are ten [grades of] impurity that emanate from a person:A person before the offering of his obligatory sacrifices is forbidden to eat holy things but permitted to eat terumah and [second] tithe. If he is a tevul yom he is forbidden to eat holy things and terumah but permitted to eat [second] tithe. If he emitted semen he is forbidden to eat any of the three. If he had intercourse with a menstruant he defiles the bottom [bedding] upon which he lies as he does the top [bedding]. If he is a zav who has seen two discharges he conveys impurity to that on which he lies or sits and is required to undergo immersion in running water, but he is exempt from the sacrifice. If he saw three discharges he must bring the sacrifice. If he is a metzora that was only enclosed he conveys impurity by entry [into an ohel] but is exempt from loosening his hair, from rending his clothes, from shaving and from the birds offering. But if he was a confirmed metzora, he is liable for all these. If a limb on which there was not the proper quantity of flesh was severed from a person, it conveys impurity by contact and by carriage but not by ohel. But if it has the proper quantity of flesh it conveys impurity by contact, by carriage and by ohel. A "proper quantity of flesh" is such as is capable of healing. Rabbi Judah says: if in one place it has flesh sufficient to surround it with [the thickness of] a thread of the woof it is capable of healing.

עֶשֶׂר קְדֻשּׁוֹת הֵן, אֶרֶץ יִשְׂרָאֵל מְקֻדֶּשֶׁת מִכָּל הָאֲרָצוֹת. וּמַה הִיא קְדֻשָּׁתָהּ, שֶׁמְּבִיאִים מִמֶּנָּה הָעֹמֶר וְהַבִּכּוּרִים וּשְׁתֵּי הַלֶּחֶם, מַה שֶּׁאֵין מְבִיאִים כֵּן מִכָּל הָאֲרָצוֹת:

There are ten grades of holiness: the land of Israel is holier than all other lands. And what is the nature of its holiness? That from it are brought the omer, the firstfruits and the two loaves, which cannot be brought from any of the other lands.

עֲיָרוֹת הַמֻּקָּפוֹת חוֹמָה מְקֻדָּשׁוֹת מִמֶּנָּה, שֶׁמְּשַׁלְּחִים מִתּוֹכָן אֶת הַמְּצֹרָעִים, וּמְסַבְּבִין לְתוֹכָן מֵת עַד שֶׁיִּרְצוּ. יָצָא, אֵין מַחֲזִירִין אוֹתוֹ:

Cities that are walled are holier, for metzoras must be sent out of them and a corpse, though it may be carried about within them as long as it is desired, may not be brought back once it has been taken out.

בֵּין הָאוּלָם וְלַמִּזְבֵּחַ מְקֻדָּשׁ מִמֶּנָּה, שֶׁאֵין בַּעֲלֵי מוּמִין וּפְרוּעֵי רֹאשׁ נִכְנָסִים לְשָׁם. הַהֵיכָל מְקֻדָּשׁ מִמֶּנּוּ, שֶׁאֵין נִכְנָס לְשָׁם שֶׁלֹּא רְחוּץ יָדַיִם וְרַגְלָיִם. קֹדֶשׁ הַקֳּדָשִׁים מְקֻדָּשׁ מֵהֶם, שֶׁאֵין נִכְנָס לְשָׁם אֶלָּא כֹהֵן גָּדוֹל בְּיוֹם הַכִּפּוּרִים בִּשְׁעַת הָעֲבוֹדָה. אָמַר רַבִּי יוֹסֵי, בַּחֲמִשָּׁה דְבָרִים בֵּין הָאוּלָם וְלַמִּזְבֵּחַ שָׁוֶה לַהֵיכָל, שֶׁאֵין בַּעֲלֵי מוּמִין, וּפְרוּעֵי רֹאשׁ, וּשְׁתוּיֵי יַיִן, וְשֶׁלֹּא רְחוּץ יָדַיִם וְרַגְלַיִם נִכְנָסִים לְשָׁם, וּפוֹרְשִׁין מִבֵּין הָאוּלָם וְלַמִּזְבֵּחַ בִּשְׁעַת הַקְטָרָה:

The area between the porch (ulam) and the altar is holier, for [priests] who have blemishes or unkempt hair may not enter it. The Hekhal is holier, for no one whose hands or feet are unwashed may enter it. The Holy of Holies is holier, for only the high priest, on Yom Kippur, at the time of the service, may enter it. Rabbi Yose said: in five respects the area between the porch and the altar is equal to the Hekhal, for those afflicted with blemishes or with a wild growth of hair, or who have drunk wine or whose hands or feet are unwashed may not enter there, and the people must keep away from the area between the porch and the altar when the incense is being burned.
