Leviticus 12:6-8

“ ‘After she has a son or daughter and her days of cleansing are over, the new mother must bring certain sacrifices to the Meeting Tent. She must give the priest at the entrance a year-old lamb for a burnt offering and a dove or young pigeon for a sin offering. 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. “ ‘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.’ ”
