Leviticus 15:28-30 - Purity Regulations From Female Bodily Discharges
28 When her discharge stops she must wait seven days. After that she will be clean. 29 She must take two mourning doves or two pigeons on the eighth day and bring them to the priest at the entrance to the Tent of Meeting. 30 The priest will offer one as an offering for sin and the other as a burnt offering. So in Jehovah's presence the priest will pay compensation for wrongdoing and make peace with Jehovah for the woman who had an unclean discharge.'
