Leviticus 12:6-8

“When the time of purification is completed for either a son or a daughter, the woman must bring a one-year-old lamb for a burnt offering and a young pigeon or turtledove for a purification offering. She must bring her offerings to the priest at the entrance of the Tabernacle. The priest will then present them to the LORD to purify her. Then she will be ceremonially clean again after her bleeding at childbirth. These are the instructions for a woman after the birth of a son or a daughter. “If a woman cannot afford to bring a lamb, she must bring two turtledoves or two young pigeons. One will be for the burnt offering and the other for the purification offering. The priest will sacrifice them to purify her, and she will be ceremonially clean.”
