Leviticus 12:2-7

²Speak with the children of Israel, saying: A woman, when she hath conceived and borne a male child, shall be unclean seven days; according to the days for the removal of her uncleanness, (or, her seclusion from her uncleanness,) she shall be unclean.

³And on the eighth day he shall be circumcised in the flesh of his foreskin;

⁴And she shall continue thirty and three days in the purification of blood; no sacred thing may she touch, nor may she come into the sanctuary, until the days of her purification be completed.

⁵But if she bear a female child, she shall be unclean fourteen days, according to (the law of) her separation; and sixty and six days she will remain for the purification of the blood.

⁶And when the days of her purification are complete, for the son or for the daughter, let her bring a lamb of its year for a burnt offering, and a young pigeon or a turtle dove for a sin offering, unto the door of the tabernacle of ordinance, unto the priest,

⁷Who shall offer it before the Lord, and make atonement for her, and she shall be cleansed from the uncleanness of her blood. This is the law for her who beareth male or female.
