Leviticus 15:25-30

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. 28“ ‘When she is cleansed from her discharge, she must count off seven days, and after that she will be ceremonially clean. 29On 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.

30The 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.
