Mishnah 3ג׳

הַמֵּטִיל טִפִּין עָבוֹת מִתּוֹךְ הָאַמָּה, טָמֵא, דִּבְרֵי רַבִּי אֶלְעָזָר חִסְמָא. הַמְהַרְהֵר בַּלַּיְלָה וְעָמַד וּמָצָא בְשָׂרוֹ חַם, טָמֵא. הַפּוֹלֶטֶת זֶרַע בַּיּוֹם הַשְּׁלִישִׁי, טְהוֹרָה, דִּבְרֵי רַבִּי אֶלְעָזָר בֶּן עֲזַרְיָה. רַבִּי יִשְׁמָעֵאל אוֹמֵר, פְּעָמִים שֶׁהֵם אַרְבַּע עוֹנוֹת, פְּעָמִים שֶׁהֵם חָמֵשׁ, פְּעָמִים שֶׁהֵם שֵׁשׁ. רַבִּי עֲקִיבָא אוֹמֵר, לְעוֹלָם חָמֵשׁ:

One who discharges thick drops from his member is impure, according to Rabbi Elazar Chisma. One who had [sexual] thoughts at night, and woke up and found his flesh was warm, is impure. A woman who discharges semen on the third day [since intercourse, including that day] is pure [i.e. even with only two nights and one day in between intercourse and the discharge], according to Rabbi Elazar ben Azarya. Rabbi Yishmael says: there are times [when she is pure] when there must be four time periods [in between; i.e. according to Rabbi Yishmael she is not pure until the fourth day, meaning there have to have been at least two nights and two days between intercourse and having the discharge], times when there must be five time periods [in between, i.e. two nights and three days], and times when there must be six time periods [in between, i.e. three nights and three days, for example if she had intercourse at the start of Shabbat night, she is only pure if she has the discharge on Tuesday night or later]. Rabbi Akiva says: there must always be five [time periods in between, before she is considered pure].

Mishnah 4ד׳

נָכְרִית שֶׁפָּלְטָה שִׁכְבַת זֶרַע מִיִּשְׂרָאֵל, טְמֵאָה. בַּת יִשְׂרָאֵל שֶׁפָּלְטָה שִׁכְבַת זֶרַע מִנָּכְרִי, טְהוֹרָה. הָאִשָּׁה שֶׁשִּׁמְּשָׁה בֵיתָהּ, וְיָרְדָה וְטָבְלָה, וְלֹא כִבְּדָה אֶת הַבַּיִת, כְּאִלּוּ לֹא טָבְלָה. בַּעַל קֶרִי שֶׁטָּבַל וְלֹא הֵטִיל אֶת הַמַּיִם, כְּשֶׁיָטִיל אֶת הַמַּיִם, טָמֵא. רַבִּי יוֹסֵי אוֹמֵר, בְּחוֹלֶה וּבְזָקֵן, טָמֵא. בְּיֶלֶד וּבְבָרִיא, טָהוֹר:

A gentile woman who discharges semen from a Jew is impure. A Jewish woman who discharges semen from a gentile is pure. If a woman had intercourse with her husband, [literally: her house] and she descended and immersed but did not clean herself [literally: clean the house], it is as though she did not immerse. If ba'al keri immersed before urinating, when he urinates he becomes impure. Rabbi Yose says: [only] regarding one who was sick or elderly is he impure; but a child or a healthy person is pure.
