Leviticus 15:28-30

Darby Translation

²⁸ And if she be cleansed of her flux then she shall count seven days, and after that she shall be clean.

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.
