Leviticus 12:4-8

4She will continue in purification from her bleeding for thirty-three days. She must not touch any holy thing or go into the sanctuary until completing her days of purification.

5But if she gives birth to a female child, she will be unclean for two weeks as she is during her menstrual impurity. She will continue in purification from her bleeding for sixty-six days.

6“When her days of purification are complete, whether for a son or daughter, she is to bring to the priest at the entrance to the tent of meeting a year-old male lamb for a burnt offering, and a young pigeon or a turtledove for a sin offering.

7He will present them before the Lord and make atonement on her behalf; she will be clean from her discharge of blood. This is the law for a woman giving birth, whether to a male or female.

8But if she doesn’t have sufficient means for a sheep, she may take two turtledoves or two young pigeons, one for a burnt offering and the other for a sin offering. Then the priest will make atonement on her behalf, and she will be clean.”
