זבים א׳Zavim 1

Mishnah 1א׳

הָרוֹאֶה רְאִיָּה אַחַת שֶׁל זוֹב, בֵּית שַׁמַּאי אוֹמְרִים, כְּשׁוֹמֶרֶת יוֹם כְּנֶגֶד יוֹם. וּבֵית הִלֵּל אוֹמְרִים, כְּבַעַל קֶרִי. רָאָה אַחַת, וּבַשֵּׁנִי הִפְסִיק, וּבַשְּׁלִישִׁי רָאָה שְׁתַּיִם אוֹ אַחַת מְרֻבָּה כִשְׁתַּיִם, בֵּית שַׁמַּאי אוֹמְרִים, זָב גָּמוּר. וּבֵית הִלֵּל אוֹמְרִים, מְטַמֵּא מִשְׁכָּב וּמוֹשָׁב, וְצָרִיךְ בִּיאַת מַיִם חַיִּים, וּפָטוּר מִן הַקָּרְבָּן. אָמַר רַבִּי אֱלִיעֶזֶר בֶּן יְהוּדָה, מוֹדִים בֵּית שַׁמַּאי בָּזֶה שֶׁאֵינוֹ זָב גָּמוּר. וְעַל מַה נֶּחְלְקוּ, עַל הָרוֹאֶה שְׁתַּיִם אוֹ אַחַת מְרֻבָּה כִשְׁתַּיִם, וּבַשֵּׁנִי הִפְסִיק, וּבַשְּׁלִישִׁי רָאָה אַחַת, בֵּית שַׁמַּאי אוֹמְרִים, זָב גָּמוּר. וּבֵית הִלֵּל אוֹמְרִים, מְטַמֵּא מִשְׁכָּב וּמוֹשָׁב, וְצָרִיךְ בִּיאַת מַיִם חַיִּים, וּפָטוּר מִן הַקָּרְבָּן:

One who has seen one abnormal genital discharge, Beit Shammai say, he is like a [woman] who observes [for emissions] a day against a day [whatever he lies or sits on becomes unclean]. Beit Hillel say he is like a ba'al keri [one who had an emission of semen whether by nocturnal emission or by sexual activity; whatever he lies or sits on does not become unclean]. If he saw [a discharge] one day and on the second day it stopped and then on the third day saw two [discharges] or one [discharge] as profuse as two, Beit Shammai say he is a full fledged zav [a male who has seen the discharge which renders him unclean]. Beit Hillel say, he renders unclean those item he sits or lies upon and he requires immersion in running water but he does not have to bring a sacrifice. Rabbi Elazar the son of Yehuda said, Beit Shammai agree in this case that he is not a full fledged zav, rather they disagree in a case where [on the first day] he sees two [discharges] or one [discharge] as profuse [the volume] as two , and on the second day it stopped and then on the third day [he once again] had one discharge, [in this case] Beit Shammai say he is a full fledged zav and Beit Hillel say, he renders unclean those items he sits or lies upon and he requires immersion in running water but he does not have to bring a sacrifice.

Mishnah 2ב׳

הָרוֹאֶה קֶרִי בַּיּוֹם הַשְּׁלִישִׁי לִסְפִירַת זוֹבוֹ, בֵּית שַׁמַּאי אוֹמְרִים, סוֹתֵר שְׁנֵי יָמִים שֶׁלְּפָנָיו. וּבֵית הִלֵּל אוֹמְרִים, לֹא סָתַר אֶלָּא יוֹמוֹ. רַבִּי יִשְׁמָעֵאל אוֹמֵר, הָרוֹאֶה בַשֵּׁנִי, סוֹתֵר אֶת שֶׁלְּפָנָיו. רַבִּי עֲקִיבָא אוֹמֵר, אֶחָד הָרוֹאֶה בַשֵּׁנִי וְאֶחָד הָרוֹאֶה בַשְּׁלִישִׁי, שֶׁבֵּית שַׁמַּאי אוֹמְרִים, סָתַר שְׁנֵי יָמִים שֶׁלְּפָנָיו. וּבֵית הִלֵּל אוֹמְרִים, לֹא סָתַר אֶלָּא יוֹמוֹ. וּמוֹדִים בְּרוֹאֶה בָרְבִיעִי שֶׁלֹּא סָתַר אֶלָּא יוֹמוֹ, בְּרָאָה קֶרִי. אֲבָל אִם רָאָה זוֹב, אֲפִלּוּ יוֹם שְׁבִיעִי, סָתַר אֶת שֶׁלְּפָנָיו:

One who sees a keri [seminal discharge] on the third day of counting after after his abnormal genital discharge, Beit Shammai say, it voids the two [clean] days that preceded it [and he must start counting again], Beit Hillel say it only voids that day [and he can continue his count the next day]. Rabbi Yishmael says, If he saw it on the second day it voids the preceding day. Rabbi Akiva says, it makes no difference if he saw it on the second day or third day, [in either case] Beit Shammai say it voids the two preceding days, and Beit Hillel say it only voids that day. They agree, however, that if he saw it on the fourth day [of his counting] it only voids that day [provided that what] he saw was a seminal emission. If, however, if he saw an abnormal seminal discharge emission, even on the seventh day, it voids [all] previous days.
