Leviticus 12:7-8

Amplified Bible

⁷ and he shall offer it before the Lord and make atonement for her, and she shall be cleansed from the flow of her blood. This is the law for her who gives birth to a child, whether a male or a female child. ⁸ If she cannot afford a lamb then she shall take two turtledoves or young pigeons, one as a burnt offering, the other as a sin offering; the priest shall make atonement for her, and she will be clean.’”^(A)
