Leviticus 12:4-6

New Catholic Bible

⁴ Then she shall continue for thirty-three days in the blood of her purifying. She shall not touch any holy thing nor shall she enter into the sanctuary until the days of her purification are complete. 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.
