Leviticus 15:19-33

“Whenever a woman has her menstrual period, she will be ceremonially unclean for seven days. Anyone who touches her during that time will be unclean until evening. Anything on which the woman lies or sits during the time of her period will be unclean. If any of you touch her bed, you must wash your clothes and bathe yourself in water, and you will remain unclean until evening. If you touch any object she has sat on, you must wash your clothes and bathe yourself in water, and you will remain unclean until evening. This includes her bed or any other object she has sat on; you will be unclean until evening if you touch it. If a man has sexual intercourse with her and her blood touches him, her menstrual impurity will be transmitted to him. He will remain unclean for seven days, and any bed on which he lies will be unclean. “If a woman has a flow of blood for many days that is unrelated to her menstrual period, or if the blood continues beyond the normal period, she is ceremonially unclean. As during her menstrual period, the woman will be unclean as long as the discharge continues. Any bed she lies on and any object she sits on during that time will be unclean, just as during her normal menstrual period. 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. “When the woman’s bleeding stops, she must count off seven days. Then she will be ceremonially clean. 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. 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. “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. These are the instructions for dealing with anyone who has a bodily discharge—a man who is unclean because of an emission of semen 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.”
