Leviticus 15:24-26

New Century Version

²⁴ “‘If a man has sexual relations with a woman and her monthly period touches him, he will be unclean for seven days; every bed he lies on will be unclean.

²⁵ “‘If a woman has a loss of blood for many days and it is not during her regular monthly period, or if she continues to have a loss of blood after her regular period, she will be unclean, as she is during her monthly period. She will be unclean for as long as she continues to bleed. ²⁶ Any bed she lies on during all the time of her bleeding will be like her bed during her regular monthly period. Everything she sits on will be unclean, as during her regular monthly period.
