Leviticus 15:29-31

Living Bible

²⁹ “On the eighth day, she shall take two turtledoves or two young pigeons and bring them to the priest at the entrance of the Tabernacle, ³⁰ and the priest shall offer one for a sin offering and the other for a burnt offering, and make atonement for her before the Lord for her menstrual defilement. ³¹ In this way you shall cleanse the people of Israel from their defilement, lest they die because of defiling my Tabernacle that is among them.”
