Le Lévitique 15:33 Commentaire : Rashi, Sforno, Rabbeinu Bahya & Siftei Chakhamim

והזב את זובו — This refers to anyone who has two appearances and to anyone who has three appearances, the law regarding whom is set forth above (cf. Rashi on v. 3).

והדוה בנדתה, the word דוה alludes to something sinful, hence she became ritually defiled.

והדוה בנדתה, “concerning a woman experiencing this flow, etc.” The sequence in which the Torah has arranged all the paragraphs describing these sources of impurity originating in our bodies is this: the Torah first listed the male who experiences an involuntary discharge of something similar to seminal fluid (verse 2); next the Torah writes about the result of cohabitation between man and woman (verse 18) resulting in contamination, seeing that also the first example (verse 16) of man having a nocturnal emission had resulted in such contamination. As a result, the Torah here can write: “this is the legislation concerning the male who experiences a discharge” (verse 32). This is followed by the woman who experiences a vaginal discharge at times other than her menstrual cycle, followed by the woman who experiences her regular menstrual cycle (verse 33). At the very conclusion of our portion the Torah speaks about someone who defies this legislation by cohabiting with a woman while she is contaminated through vaginal discharge of either kind.
