Leviticus 12:6

4She 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.

5But 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.

6“‘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.

7He shall offer it before the LORD, and make atonement for her; then she shall be cleansed from the fountain of her blood. “‘This is the law for her who bears, whether a male or a female.

8If she cannot afford a lamb, then she shall take two turtledoves or two young pigeons: the one for a burnt offering, and the other for a sin offering. The priest shall make atonement for her, and she shall be clean.’”
