Leviticus 12:6-8

ERV(i) 6 And when the days of her purifying are fulfilled, for a son, or for a daughter, she shall bring a lamb of the first year for a burnt offering, and a young pigeon, or a turtledove, for a sin offering, unto the door of the tent of meeting, unto the priest: 7 and he shall offer it before the LORD, 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. 8 And if her means suffice not for 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: and the priest shall make atonement for her, and she shall be clean.
