Leviticus 12:2-7

²Speak to the children of Israel, saying, If a woman hath conceived seed, and borne a male-child; then she shall be unclean seven days; according to the days of the separation for her infirmity shall she be unclean.

³And in the eighth day the flesh of his foreskin shall be circumcised.

⁴And she shall then continue in the blood of her purifying three and thirty days: she shall touch no hallowed thing, nor come into the sanctuary, until the days of her purifying be fulfilled.

⁵But if she shall bear a female-child, then she shall be unclean two weeks, as in her separation: and she shall continue in the blood of her purifying sixty six days.

⁶And 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 turtle-dove, for a sin-offering, to the door of the tabernacle of the congregation, to the priest;

⁷Who shall offer it before the LORD, and make an atonement for her; and she shall be cleansed from the issue of her blood. This is the law for her that hath borne a male or a female.
