Leviticus 15
24 Ref `And if a man really lie with her, and her separation is on him, then he hath been unclean seven days, and all the bed on which he lieth is unclean.
25 Ref `And when a woman's issue of blood floweth many days within the time of her separation, or when it floweth over her separation -- all the days of the issue of her uncleanness are as the days of her separation; she `is' unclean.
