Do not uncover the nakedness of ... you must not uncover her nakedness

Here the idiom "uncover the nakedness" of someone means "have sexual relations" with someone. See how you translated this idiom in Leviticus 18:6. Alternate translation: "Do not have sexual relations with ... you must not have sexual relations with her" (See: rc://en/ta/man/jit/figs-idiom)
