Leviticus 12:5-7

New Catholic Bible

⁵ But if she gives birth to a girl, she shall be unclean for two weeks as during her menstruation. She shall continue in the blood of her purifying for sixty-six days.^[a]

⁶ “When the days of her purification for a son or a daughter are complete, she shall bring a year-old lamb as a burnt offering and a pigeon or a turtledove as a sin offering to the priest at the entrance to the meeting tent. ⁷ He shall offer it before the Lord and make atonement for her. She shall be cleansed from the flow of her blood. This is the law for a woman who has borne a male or female child.
