Leviticus 15:19-31

“When a woman has a discharge of blood, the impurity of her menstrual period lasts seven days. Anyone who touches her is unclean until evening. Everything on which she lies or sits during her period is unclean. Anyone who touches her bed or anything on which she sits must wash his clothes and bathe in water; he remains unclean until evening. “If a man sleeps with her and her menstrual blood gets on him, he is unclean for seven days and every bed on which he lies becomes unclean. “If a woman has a discharge of blood for many days, but not at the time of her monthly period, or has a discharge that continues beyond the time of her period, she is unclean the same as during the time of her period. Every bed on which she lies during the time of the discharge and everything on which she sits becomes unclean the same as in her monthly period. Anyone who touches these things becomes unclean and must wash his clothes and bathe in water; he remains unclean until evening. “When she is cleansed from her discharge, she is to count off seven days; then she is clean. On the eighth day she is to take two doves or two pigeons and bring them to the priest at the entrance to the Tent of Meeting. The priest will offer one for an Absolution-Offering and the other for a Whole-Burnt-Offering. The priest will make atonement for her in the presence of GOD because of the discharge that made her unclean. “You are responsible for keeping the People of Israel separate from that which makes them ritually unclean, lest they die in their unclean condition by defiling my Dwelling which is among them.
