Leviticus 15:29

27Whoever touches these things shall be unclean, and shall wash his clothes and bathe himself in water, and be unclean until the evening.

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

29On 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.

30The 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.

31“‘Thus you shall separate the children of Israel from their uncleanness, so they will not die in their uncleanness when they defile my tabernacle that is among them.’”
