Leviticus 15:28-30

American Standard Version

²⁸ But if she be cleansed of her issue, then she shall number to herself seven days, and after that she shall be clean. ²⁹ And on the eighth day she shall take unto her two turtle-doves, or two young pigeons, and bring them unto the priest, to the door of the tent of meeting. ³⁰ And the priest shall offer the one for a sin-offering, and the other for a burnt-offering; and the priest shall make atonement for her before Jehovah for the issue of her uncleanness.
