Leviticus 15:27

“‘If any man lies with her, and her monthly flow is on him, he shall be unclean seven days; and every bed he lies on shall be unclean.

“‘If a woman has a discharge of her blood many days not in the time of her period, or if she has a discharge beyond the time of her period, all the days of the discharge of her uncleanness shall be as in the days of her period. She is unclean.

Every bed she lies on all the days of her discharge shall be to her as the bed of her period. Everything she sits on shall be unclean, as the uncleanness of her period.

“‘But if she is cleansed of her discharge, then she shall count to herself seven days, and after that she shall be clean.

On the eighth day she shall take two turtledoves, or two young pigeons, and bring them to the priest, to the door of the Tent of Meeting.

The priest shall offer the one for a sin offering, and the other for a burnt offering; and the priest shall make atonement for her before the LORD for the uncleanness of her discharge.
