Leviticus 12:4-6

4Then she will remain thirty-three days in blood purity. She must not touch anything holy and she must not enter the sanctuary until the days of her purification are fulfilled.

5If she bears a female child, she will be impure fourteen days as during her menstrual flow, and she will remain sixty-six days in blood purity.

6“‘When the days of her purification are completed for a son or for a daughter, she must bring a one year old lamb for a burnt offering and a young pigeon or turtledove for a sin offering to the entrance of the Meeting Tent, to the priest.
