Leviticus 12:6, 8

‘When the days of her purification are fulfilled, whether for a son or a daughter, she shall bring to the priest a lamb of the first year as a burnt offering, and a young pigeon or a turtledove as a sin offering, to the door of the tabernacle of meeting.

‘And if she is not able to bring a lamb, then she may bring two turtledoves or two young pigeons—one as a burnt offering and the other as a sin offering. So the priest shall make atonement for her, and she will be clean.’ ”
