Leviticus 12:7-8

New Century Version

⁷ He will offer them before the Lord to make her clean so she will belong to the Lord again; then she will be clean from her loss of blood. These are the teachings for a woman who gives birth to a boy or girl.

⁸ “‘If she cannot afford a lamb, she is to bring two doves or two young pigeons, one for a burnt offering and one for a sin offering. In this way the priest will make her clean so she will belong to the Lord again, and she will be clean.’”
