Leviticus 15:16-28

16“Whenever a man has an emission of semen, he must bathe his entire body in water, and he will remain ceremonially unclean until the next evening.

17Any clothing or leather with semen on it must be washed in water, and it will remain unclean until evening.

18After a man and a woman have sexual intercourse, they must each bathe in water, and they will remain unclean until the next evening.

19“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.

20Anything on which the woman lies or sits during the time of her period will be unclean.

21If any of you touch her bed, you must wash your clothes and bathe yourself in water, and you will remain unclean until evening.

22If 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.

23This includes her bed or any other object she has sat on; you will be unclean until evening if you touch it.

24If 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.

25“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.

26Any bed she lies on and any object she sits on during that time will be unclean, just as during her normal menstrual period.

27If 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.
