Leviticus 15:29-33

MSB(i) 29 On the eighth day she is to take two turtledoves or two young pigeons and bring them to the priest at the entrance to the Tent of Meeting. 30 The priest is to sacrifice one as a sin offering and the other as a burnt offering. In this way the priest will make atonement for her before the LORD for her unclean discharge. 31 You must keep the children of Israel separate from their uncleanness, so that they do not die by defiling My tabernacle, which is among them. 32 This is the law of him who has a discharge, of the man who has an emission of semen whereby he is unclean, 33 of a woman in her menstrual period, of any male or female who has a discharge, and of a man who lies with an unclean woman.’”
