Leviticus 12:2-6

“Speak to the sons of Israel, saying: ‘When a woman gives birth and delivers a male child, then she shall be unclean for seven days; as she is in the days of her menstruation, she shall be unclean.

Then on the eighth day the flesh of his foreskin shall be circumcised.

And she shall stay at home in her condition of blood purification for thirty-three days; she shall not touch any consecrated thing, nor enter the sanctuary until the days of her purification are completed.

But if she gives birth to a female child, then she shall be unclean for two weeks, as in her menstruation; and she shall stay at home in her condition of blood 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 as a burnt offering and a young pigeon or a turtledove as a sin offering.
