Leviticus 15:25-30

²⁵ 'And when a woman's issue of blood floweth many days within the time of her separation, or when it floweth over her separation—all the days of the issue of her uncleanness are as the days of her separation; she 'is' unclean. ²⁶ 'All the bed on which she lieth all the days of her issue is as the bed of her separation to her, and all the vessel on which she sitteth is unclean as the uncleanness of her separation; ²⁷ and any one who is coming against them is unclean, and hath washed his garments, and hath bathed with water, and been unclean till the evening. ²⁸ 'And if she hath been clean from her issue, then she hath numbered to herself seven days, and afterwards she is clean; ²⁹ and on the eighth day she taketh to herself two turtle-doves, or two young pigeons, and hath brought them in unto the priest, unto the opening of the tent of meeting; ³⁰ and the priest hath made the one a sin-offering, and the one a burnt-offering, and the priest hath made atonement for her before Jehovah, because of the issue of her uncleanness.
