הַכֹּל מִטַּמְּאִין בְּזִיבָה, אַף הַגֵּרִים, אַף הָעֲבָדִים, בֵּין מְשֻׁחְרָרִין בֵּין שֶׁאֵינָן מְשֻׁחְרָרִין, חֵרֵשׁ, שׁוֹטֶה, וְקָטָן, סְרִיס אָדָם, סְרִיס חַמָּה. טֻמְטוּם וְאַנְדְּרוֹגִינוֹס, נוֹתְנִין עֲלֵיהֶן חֻמְרֵי הָאִישׁ וְחֻמְרֵי הָאִשָּׁה, מִטַּמְּאִין בְּדָם כָּאִשָּׁה וּבְלֹבֶן כָּאִישׁ, וְטֻמְאָתָן בְּסָפֵק: All persons become unclean through zivah, even converts, even slaves whether freed or not, a deaf-mute, a person of unsound senses, and a minor, a eunuch whether [he had been castrated] by man, or was a eunuch from [the time of seeing] the sun. With regard to a tumtum and an androgynous [person], they place upon him the stringencies for a man and the stringencies for a woman: they defile through blood like a woman, and through eggy [substance] like a man. Their uncleanness still remains in doubt.
בְּשִׁבְעָה דְרָכִים בּוֹדְקִין אֶת הַזָּב עַד שֶׁלֹּא נִזְקַק לְזִיבָה. בְּמַאֲכָל, בְּמִשְׁתֶּה, וּבְמַשָּׂא, בִּקְפִיצָה, בְּחֹלִי, וּבְמַרְאֶה וּבְהִרְהוּר. הִרְהֵר עַד שֶׁלֹּא רָאָה אוֹ שֶׁרָאָה עַד שֶׁלֹּא הִרְהֵר. רַבִּי יְהוּדָה אוֹמֵר, אֲפִלּוּ רָאָה בְהֵמָה, חַיָּה וָעוֹף מִתְעַסְּקִין זֶה עִם זֶה, אֲפִלּוּ רָאָה בִגְדֵי צֶבַע הָאִשָּׁה. רַבִּי עֲקִיבָא אוֹמֵר, אֲפִלּוּ אָכַל כָּל מַאֲכָל, בֵּין רַע בֵּין יָפֶה, וְשָׁתָה כָל מַשְׁקֶה. אָמְרוּ לוֹ, אֵין כָּאן זָבִין מֵעָתָּה. אָמַר לָהֶם, אֵין אַחֲרָיוּת זָבִים עֲלֵיכֶם. מִשֶּׁנִּזְקַק לְזִיבָה, אֵין בּוֹדְקִין אוֹתוֹ. אָנְסוֹ וּסְפֵקוֹ וְשִׁכְבַת זַרְעוֹ טְמֵאִים, שֶׁרַגְלַיִם לַדָּבָר. רָאָה רְאִיָּה רִאשׁוֹנָה, בּוֹדְקִין אוֹתוֹ. בַּשְּׁנִיָּה, בּוֹדְקִין אוֹתוֹ. בַּשְּׁלִישִׁית, אֵין בּוֹדְקִין אוֹתוֹ. רַבִּי אֱלִיעֶזֶר אוֹמֵר, אַף בַּשְּׁלִישִׁית בּוֹדְקִין אוֹתוֹ, מִפְּנֵי הַקָּרְבָּן: There are seven ways in which a zav is examined as long as he had not become subject to zivah: With regard to food, drink, as [to what] he had carried, whether he had jumped, whether he had been ill, what he had seen, or what he had thought. [It doesn't matter] whether he had thoughts before seeing [a woman], or whether he had seen [a woman] before his thoughts. Rabbi Judah says: even if he had watched beasts, wild animals or birds having intercourse with each other, and even when he had seen a woman's dyed garments. Rabbi Akiva says: even if he had eaten any kind of food, be it good or bad, or had drunk any kind of liquid. They said to him: Then there will be no zavim in the world!’ He replied to them: you are not held responsible for the existence of zavim!’ Once he had become subject to zivah, no further examination takes place. [Zov] resulting from an accident, or that was at all doubtful, or an issue of semen, these are unclean, since there are grounds for the assumption [that it is zivah]. If he had at a first [issue] they examine him; On the second [issue] they examine him, but on the third [issue] they don't examine him. Rabbi Eliezer says: even on the third [issue] they examine him because of the sacrifice.
הָרוֹאֶה קֶרִי, אֵינוֹ מִטַּמֵּא בְזִיבָה מֵעֵת לְעֵת. רַבִּי יוֹסֵי אוֹמֵר, יוֹמוֹ. נָכְרִי שֶׁרָאָה קֶרִי וְנִתְגַּיֵּר, מִיָּד הוּא מִטַּמֵּא בְזִיבָה. הָרוֹאָה דָם וְהַמַּקְשָׁה, מֵעֵת לְעֵת. וְהַמַּכֶּה אֶת עַבְדּוֹ יוֹם יוֹמַיִם, מֵעֵת לְעֵת. כֶּלֶב שֶׁאָכַל בְּשַׂר הַמֵּת, שְׁלשָׁה יָמִים מֵעֵת לְעֵת, הֲרֵי הוּא כִבְרִיָּתוֹ: One who had [a discharge of] semen does not defile due to zivah for a period of twenty-four hours. Rabbi Yose says: [only] that day. A non-Jew who had a discharge of semen and then converted, he immediately becomes unclean due to zivah. [A woman] who had [an issue] of blood, or had experienced difficulty [in childbirth], [the time prescribed] is twenty-four hours. One who strikes his slave, the "day or two" is twenty-four hours. A dog that eats a corpse's flesh, for three days from one time of day to the same time of day, it is considered to be in its natural state.
הַזָּב מְטַמֵּא אֶת הַמִּשְׁכָּב בַּחֲמִשָּׁה דְרָכִים, לְטַמֵּא אָדָם לְטַמֵּא בְגָדִים. עוֹמֵד, יוֹשֵׁב, שׁוֹכֵב, נִתְלֶה וְנִשְׁעָן. וְהַמִּשְׁכָּב מְטַמֵּא אֶת הָאָדָם בְּשִׁבְעָה דְרָכִים לְטַמֵּא בְגָדִים. עוֹמֵד, יוֹשֵׁב, שׁוֹכֵב, נִתְלֶה, וְנִשְׁעָן, בְּמַגָּע וּבְמַשָּׂא: A zav defiles the objects that are lain upon (or sat upon) in five ways, so that they defile people and garments: by standing, sitting, lying, hanging or leaning. What he lies upon defiles a person in seven ways, so that he [in turn] defiles garments: by standing, sitting, lying, hanging, or leaning upon it, or by touching or carrying it.
