Leviticus 12:5-7

But if she bears a female child, then she shall be unclean for two weeks, as in her menstruation; and she shall remain in the blood of her purification for sixty-six days. ‘When 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 for a sin offering. Then he shall offer it before the LORD and make atonement for her, and she shall be cleansed from the flow of her blood. This is the law for her who bears a child, whether a male or a female.
