Leviticus 15:31-33

31‘Thus you shall separate the children of Israel from their uncleanness, lest they die in their uncleanness when they defile My tabernacle that is among them.

32This is the law for one who has a discharge, and for him who emits semen and is unclean thereby,

33and for her who is indisposed because of her customary impurity, and for one who has a discharge, either man or woman, and for him who lies with her who is unclean.’ ”
