Leviticus 15:24-27

²⁴'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'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.

²⁶'All the bed on which she lieth all the days of her issue is as the bed of her separation to her, and all the vessel on which she sitteth is unclean as the uncleanness of her separation;

²⁷and any one who is coming against them is unclean, and hath washed his garments, and hath bathed with water, and been unclean till the evening.
