Leviticus 12:5-6

5After a girl is born, her mother will not be clean for two weeks. The rule is the same as for each month, when she is bleeding. She will not be clean then. She must wait 66 days after a girl is born. Then she will become clean.

6When the days to wait are finished, the woman must come to the door of the Tent of Meeting. She must bring to the priest a sheep that is one year old for a burnt offering. And she must bring a bird for a sin offering. The bird must be a pigeon or a dove. These are gifts to God.
