Leviticus 15:27-33

²⁷And whoever toucheth them shall be unclean, and shall wash his clothes, and bathe in water, and be unclean until the even.

²⁸And if she be cleansed of her flux then she shall count seven days, and after that she shall be clean.

²⁹And on the eighth day she shall take two turtle-doves, or two young pigeons, and bring them unto the priest, unto the entrance of the tent of meeting.

³⁰And the priest shall offer the one as a sin-offering, and the other as a burnt-offering; and the priest shall make atonement for her before Jehovah for the flux of her uncleanness.

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.
