Leviticus 12:4-6

4And she shall stay at home in her condition of 1blood purification for thirty-three days; she shall not touch any consecrated thing, nor enter the sanctuary until the days of her purification are completed. 5But 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 2blood purification for sixty-six days.

6‘3When 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 4as a 5sin offering.
