Leviticus 15:25-29 New Revised Standard Version (NRSV)
25 If a woman has a discharge of blood for many days, not at the time of her impurity, or if she has a discharge beyond the time of her impurity, all the days of the discharge she shall continue in uncleanness; as in the days of her impurity, she shall be unclean. 26 Every bed on which she lies during all the days of her discharge shall be treated as the bed of her impurity; and everything on which she sits shall be unclean, as in the uncleanness of her impurity. 27 Whoever touches these things shall be unclean, and shall wash his clothes, and bathe in water, and be unclean until the evening. 28 If she is cleansed of her discharge, she shall count seven days, and after that she shall be clean. 29 On the eighth day she shall take two turtledoves or two pigeons and bring them to the priest at the entrance of the tent of meeting.
