Leviticus 12:2–8

²“Say to the Israelites: ‘A woman who becomes pregnant and gives birth to a son will be ceremonially unclean for seven days, just as she is unclean during her monthly period.^{e 3}On the eighth day^f the boy is to be circumcised.^{g 4}Then the woman must wait thirty-three days to be purified from her bleeding. She must not touch anything sacred or go to the sanctuary until the days of her purification are over. ⁵If she gives birth to a daughter, for two weeks the woman will be unclean, as during her period. Then she must wait sixty-six days to be purified from her bleeding.

⁶“ ‘When the days of her purification for a son or daughter are over,^h she is to bring to the priest at the entrance to the tent of meeting a year-old lambⁱ for a burnt offering and a young pigeon or a dove for a sin offering.^{aj 7}He shall offer them before the Lord to make atonement for her, and then she will be ceremonially clean from her flow of blood.

“ ‘These are the regulations for the woman who gives birth to a boy or a girl. ⁸But if she cannot afford a lamb, she is to bring two doves or two young pigeons,^k one for a burnt offering and the other for a sin offering.^l In this way the priest will make atonement for her, and she will be clean.^m’ ”
