Leviticus 15:27-33

27 If any of you touch these things, you will be ceremonially unclean. You must wash your clothes and bathe yourself in water, and you will remain unclean until evening.
28 “When the woman’s bleeding stops, she must count off seven days. Then she will be ceremonially clean.
29 On the eighth day she must bring two turtledoves or two young pigeons and present them to the priest at the entrance of the Tabernacle.
30 The priest will offer one for a sin offering and the other for a burnt offering. Through this process, the priest will purify her before the LORD for the ceremonial impurity caused by her bleeding.
31 “This is how you will guard the people of Israel from ceremonial uncleanness. Otherwise they would die, for their impurity would defile my Tabernacle that stands among them.
32 These are the instructions for dealing with anyone who has a bodily discharge—a man who is unclean because of an emission of semen
33 or a woman during her menstrual period. It applies to any man or woman who has a bodily discharge, and to a man who has sexual intercourse with a woman who is ceremonially unclean.”
