Leviticus 12:7-8

Young's Literal Translation

⁷ and he hath brought it near before Jehovah, and hath made atonement for her, and she hath been cleansed from the fountain of her blood; this [is] the law of her who is bearing, in regard to a male or to a female.

⁸ `And if her hand find not the sufficiency of a sheep, then she hath taken two turtle-doves, or two young pigeons, one for a burnt-offering, and one for a sin-offering, and the priest hath made atonement for her, and she hath been cleansed.'
