God spoke to Moses:
"Tell the People of Israel: A woman who conceives and gives birth to a boy is ritually unclean for seven days, the same as during her menstruation.
On the eighth day circumcise the boy.
The mother must stay home another thirty-three days for purification from her bleeding. She may not touch anything consecrated or enter the Sanctuary until the days of her purification are complete.
If she gives birth to a girl, she is unclean for fourteen days, the same as during her menstruation. She must stay home for sixty-six days for purification from her bleeding.
"When the days for her purification for either a boy or a girl are complete, she will bring a yearling lamb for a Whole-Burnt-Offering and a pigeon or dove for an Absolution-Offering to the priest at the entrance of the Tent of Meeting.
He will offer it to God and make atonement for her. She is then clean from her flow of blood. "These are the instructions for a woman who gives birth to either a boy or a girl.
"If she can't afford a lamb, she can bring two doves or two pigeons, one for the Whole-Burnt-Offering and one for the Absolution-Offering. The priest will make atonement for her and she will be clean."
