Leviticus 15:29-31

Young's Literal Translation

²⁹ and on the eighth day she taketh to herself two turtle-doves, or two young pigeons, and hath brought them in unto the priest, unto the opening of the tent of meeting;

³⁰ and the priest hath made the one a sin-offering, and the one a burnt-offering, and the priest hath made atonement for her before Jehovah, because of the issue of her uncleanness.

³¹ `And ye have separated the sons of Israel from their uncleanness, and they die not in their uncleanness, in their defiling My tabernacle which [is] in their midst.
