²⁹ Then on the eighth day she shall take for herself two turtledoves or two young pigeons and bring them to the priest at the doorway of the Tent of Meeting; ³⁰ and the priest shall offer one as a sin offering and the other as a burnt offering; and he shall make atonement for her before the Lord for her unclean discharge.’
