Leviticus 15:19-33
New International Version (NIV1984)
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. 21 Whoever touches her bed must wash his clothes and bathe with water, and he will be unclean till evening. 22 Whoever touches anything she sits on must wash his clothes and bathe with water, and he will be unclean till evening. 23 Whether it is the bed or anything she was sitting on, when anyone touches it, he will be unclean till evening.
24 “ ‘If a man lies 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. 26 Any 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. 27 Whoever touches them will be unclean; he must wash his clothes and bathe with water, and he will be unclean till evening.
28 “ ‘When she is cleansed from her discharge, she must count off seven days, and after that she will be ceremonially clean. 29 On the eighth day she must take two doves or two young pigeons and bring them to the priest at the entrance to the Tent of Meeting. 30 The priest is to sacrifice one for a sin offering and the other for a burnt offering. In this way he will make atonement for her before the Lord for the uncleanness of her discharge.
31 “ ‘You must keep the Israelites separate from things that make them unclean, so they will not die in their uncleanness for defiling my dwelling place, which is among them.’ ”
32 These are the regulations for a man with a discharge, for anyone made unclean by an emission of semen, 33 for a woman in her monthly period, for a man or a woman with a discharge, and for a man who lies with a woman who is ceremonially unclean.
