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.

“ ‘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.’ ”
