'Menstrual' in the Bible

"Speak to the {Israelites}, saying, 'When a woman becomes pregnant and she gives birth to a male, then she shall be unclean seven days--as [in] the time of her menstrual bleeding, she shall become unclean.

" 'And you must not {have sex with} a woman to expose her nakedness {during} her menstrual uncleanness.

And we all have become like the unclean, and all our deeds of justice like a menstrual cloth, And we all wither like leaf, and our iniquities take us away like the wind.
