Leviticus 12:5-7

New Revised Standard Version, Anglicised Catholic Edition

⁵ If she bears a female child, she shall be unclean for two weeks, as in her menstruation; her time of blood purification shall be sixty-six days.

⁶ When the days of her purification are completed, whether for a son or for a daughter, she shall bring to the priest at the entrance of the tent of meeting a lamb in its first year for a burnt-offering, and a pigeon or a turtle-dove for a sin-offering. ⁷ He shall offer it before the Lord, and make atonement on her behalf; then she shall be clean from her flow of blood. This is the law for her who bears a child, male or female.
