Leviticus 12:6-7

ASV(i) 6 And when the days of her purifying are fulfilled, for a son, or for a daughter, she shall bring a lamb a year old for a burnt-offering, and a young pigeon, or a turtle-dove, for a sin-offering, unto the door of the tent of meeting, unto the priest: 7 and he shall offer it before Jehovah, and make atonement for her; and she shall be cleansed from the fountain of her blood. This is the law for her that beareth, whether a male or a female.
