dan tentang perempuan yang sedang sakit dalam masa haidnya, dan tentang orang yang mengeluarkan lelehan, baik laki-laki maupun perempuan, dan tentang laki-laki yang tidur dengan perempuan yang najis.

תזרם כמו (אשה) דוה – that is to say, it should be in your eyes like foreigners like depressed like a menstruant woman, as it is written (Leviticus 15:33): “and concerning her who is in menstrual infirmity” and the Biblical verse is speaking about idolatry.
German Commentary
untersucht man ihn nicht. wenn er das dritte Mal den Fluss sieht. Mag auch das dritte Sehen durch eine der sieben Ursachen hervorgerufen sein, so muss er doch das Opfer bringen. Dies wird aus Lev. 15, 33 gedeutet (Talmud 65 b).
Tosafot Yom Tov
AND THEIR WORDS ARE ALL LIKE BURNING COALS. Even the slightest one of them, for in transgressing them one breaches the boundary the Sages have set. Let us take the prohibition of secluding oneself with a single woman. A single woman is assumed to be ritually impure due to menstruation, because the Sages interpret the phrase “in her impurity” (Leviticus 15:33) to mean that a menstruating woman remains impure until she immerses in water (Shabbat 64b).82And the assumption is that single women do not go to the mikveh to immerse. [And the mishna in Niddah 3:5 considers a day-old baby already legally capable of becoming impure.] But the rabbinic prohibition of seclusion applies even to a single woman who has gone and immersed herself, because the prohibition was “seclusion with a single woman”—whether pure or impure—Rashi.
