Leviticus 15:32-33

Amplified Bible

³² This is the law for the one who has a discharge and for the one who has a seminal emission, so that he is unclean by it; ³³ and for the woman who is ill because of her monthly period, and for the one who has a discharge, whether man or woman, or for a man who lies with a woman who is [ceremonially] unclean.
