Leviticus 12:3

The LORD spoke to Moses, saying,

“Speak to the children of Israel, saying, ‘If a woman conceives, and bears a male child, then she shall be unclean seven days; as in the days of her monthly period she shall be unclean.

She shall continue in the blood of purification thirty-three days. She shall not touch any holy thing, nor come into the sanctuary, until the days of her purifying are completed.

But if she bears a female child, then she shall be unclean two weeks, as in her period; and she shall continue in the blood of purification sixty-six days.

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