Leviticus 12:5-7

12:5 If 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.

12:6 “‘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. 12:7 The priest is to present it before the Lord and make atonement on her behalf, and she will be clean from her flow of blood. This is the law of the one who bears a child, for the male or the female child.
