Leviticus 12:2-6

“Speak to the children of Israel, saying, ‘ I f a woman conceives and gives birth to a male child, she shall be [ceremonially] unclean for seven days, unclean as during her monthly period. On the eighth day the flesh of the male child’s foreskin shall be circumcised. Then she shall remain [intimately separated] thirty-three days to be purified from the blood; she shall not touch any consecrated thing nor enter the [courtyard of the] sanctuary until the days of her purification are over. But if she gives birth to a female child, then she shall be unclean for two weeks, as during her monthly period, and she shall remain [intimately separated] sixty-six days to be purified from the blood. ‘When the days of her purification are completed, whether 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
