Leviticus 15:29-31

Darby Translation

²⁹ And on the eighth day she shall take two turtle-doves, or two young pigeons, and bring them unto the priest, unto the entrance of the tent of meeting.

³⁰ And the priest shall offer the one as a sin-offering, and the other as a burnt-offering; and the priest shall make atonement for her before Jehovah for the flux of her uncleanness.

³¹ And ye shall separate the children of Israel from their uncleanness, that they die not in their uncleanness, when they defile my tabernacle that is in their midst.
