וְהַדָּוָה֙ בְּנִדָּתָ֔הּ וְהַזָּב֙ אֶת־זוֹב֔וֹ לַזָּכָ֖ר וְלַנְּקֵבָ֑ה וּלְאִ֕ישׁ אֲשֶׁ֥ר יִשְׁכַּ֖ב עִם־טְמֵאָֽה׃ (פ)
불결을 앓는 여인과 유출병이 있는 남녀와 불결한 여인과 동침한 자에게 관한 것이니라
Rashi on Leviticus
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).
Sforno on Leviticus
והדוה בנדתה, the word דוה alludes to something sinful, hence she became ritually defiled.
