Leviticus 15:30

And the priest shall offer the one for a sin offering, and the other for a burnt offering; and the priest shall make an atonement for her before the LORD for the issue of her uncleanness.

The priest shall offer the one for a sin offering, and the other for a burnt offering; and the priest shall make atonement for her before Yahweh for the uncleanness of her discharge.

And the priest shall offer the one for a sin-offering, and the other for a burnt-offering; and the priest shall make atonement for her before Jehovah for the issue of her uncleanness.

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.

The priest is to sacrifice one as a sin offering and the other as a burnt offering. In this way the priest will make atonement for her before the LORD for her unclean discharge.
