Leviticus 12:5-6

5“When a woman gives birth to a girl, she will be unclean as in her monthly period. However, she will be unclean for two weeks. Then she must stay at home for 66 days in order to be made clean from her bleeding.

6“When the days needed to make her clean are over, she must bring a one-year-old lamb for a burnt offering and a pigeon or a mourning dove as an offering for sin. She must bring them to the priest at the entrance to the tent of meeting.
