וְאִשָּׁ֕ה אֲשֶׁ֨ר יִשְׁכַּ֥ב אִ֛ישׁ אֹתָ֖הּ שִׁכְבַת־זָ֑רַע וְרָחֲצ֣וּ בַמַּ֔יִם וְטָמְא֖וּ עַד־הָעָֽרֶב׃
און אַ פֿרױ, אַז אַ מאַן װעט ליגן מיט איר אַ בײַשלאָף פֿון זאָמען, זאָלן זײ זיך באָדן אין װאַסער, און זײַן אומרײן ביזן אָװנט.
Mishnah Mikvaot
If a non-Jewish woman discharged semen from an Israelite, it is unclean. If an Israelite woman discharged semen from a non-Jewish man, it is clean. If a woman had intercourse and then went down and immersed herself but did not sweep out the house, it is as though she had not immersed herself. If a man who had a seminal emission immersed himself but did not first pass urine, he again becomes unclean when he passes urine. Rabbi Yose says: if he was sick or old he is unclean, but if he was young and healthy he remains clean.
