Leviticus 15:31-33

31And ye shall separate the children of Israel from their uncleanness, that they die not in their uncleanness, when they defile my tabernacle that is in their midst. 32This is the law for him that hath a flux, and for the one whose seed of copulation goeth from him, and who is defiled therewith: 33and for a woman who is sick in her separation, and for him that hath his flux; for the man and for the woman, and for him that lieth with her that is unclean.
