Leviticus 12:4-8

4Then she shall remain in the blood of her purification for thirty-three days; she shall not touch any consecrated thing, nor enter the sanctuary until the days of her purification are completed. 5But if she bears a female child, then she shall be unclean for two weeks, as in her 1menstruation; and she shall remain in the blood of her purification for sixty-six days.

6‘2When the days of her purification are completed, for a son or for a daughter, she shall bring to the priest at the doorway of the tent of meeting a one year old lamb for a burnt offering and a young pigeon or a turtledove 3for a sin offering. 7Then he shall offer it before the Lord and make atonement for her, and she shall be cleansed from the 4flow of her blood. This is the law for her who bears a child, whether a male or a female. 8But if 5she cannot afford a lamb, then she shall take 6two turtledoves or two young pigeons, 7the one for a burnt offering and the other for a sin offering; and the 8priest shall make atonement for her, and she will be clean.’”
