Leviticus 15:22-25

²²'And any one who is coming against any vessel on which she sitteth doth wash his garments, and hath washed with water, and been unclean till the evening.

²³'And if it is on the bed, or on the vessel on which she is sitting, in his coming against it, he is unclean till the evening.

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.
