Leviticus 15:33 BBE

³¹  In this way may the children of Israel be made free from all sorts of unclean conditions, so that death may not overtake them when they are unclean and when they make unclean my holy place which is among them.

³²  This is the law for the man who has a flow from his body, or whose seed goes from him so that he is unclean;

³³  And for her who has a flow of blood, and for any man or woman who has an unclean flow, and for him who has sex relations with a woman when she is unclean.
