Leviticus 15:28-30

Revised Standard Version

²⁸ But if she is cleansed of her discharge, she shall count for herself seven days, and after that she shall be clean. 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.
