28 'And if she hath been clean from her issue, then she hath numbered to herself seven days, and afterwards she is clean; 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.
