Leviticus 15:23-25

Young's Literal Translation

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.
