Leviticus 15:29-30

New International Version

²⁹ On the eighth day she must take two doves or two young pigeons^(A) and bring them to the priest at the entrance to the tent of meeting. ³⁰ The priest is to sacrifice one for a sin offering and the other for a burnt offering. In this way he will make atonement for her before the Lord for the uncleanness of her discharge.^(B)
