Leviticus 15:29-31

Modern English Version

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. ³⁰ The priest shall offer one for a sin offering and the other for a burnt offering, and the priest shall make atonement for her before the Lord for her unclean discharge.

³¹ Thus you shall separate the children of Israel from their uncleanness, so that they do not die in their uncleanness by defiling My tabernacle that is among them.
