Leviticus 15:19-27

19“ ‘When a woman has her regular flow of blood, the impurity of her monthly period will last seven days, and anyone who touches her will be unclean till evening. 20“ ‘Anything she lies on during her period will be unclean, and anything she sits on will be unclean. 21Anyone who touches her bed will be unclean; they must wash their clothes and bathe with water, and they will be unclean till evening. 22Anyone who touches anything she sits on will be unclean; they must wash their clothes and bathe with water, and they will be unclean till evening. 23Whether it is the bed or anything she was sitting on, when anyone touches it, they will be unclean till evening. 24“ ‘If a man has sexual relations with her and her monthly flow touches him, he will be unclean for seven days; any bed he lies on will be unclean. 25“ ‘When a woman has a discharge of blood for many days at a time other than her monthly period or has a discharge that continues beyond her period, she will be unclean as long as she has the discharge, just as in the days of her period. 26Any bed she lies on while her discharge continues will be unclean, as is her bed during her monthly period, and anything she sits on will be unclean, as during her period. 27Anyone who touches them will be unclean; they must wash their clothes and bathe with water, and they will be unclean till evening.
