Leviticus 15:29-31

Revised Standard Version

²⁹ And on the eighth day she shall take two turtledoves or two young pigeons, and bring them to the priest, to the door of the tent of meeting. ³⁰ And 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 keep the people of Israel separate from their uncleanness, lest they die in their uncleanness by defiling my tabernacle that is in their midst.”
