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.
And the priest shall offer the one for a sin offering,.... As in the case of a man that had an issue, the offerings of one and the other were the same and for the same purpose; See Gill on "Leviticus 15:15"; there being a legal uncleanness in their case, atonement must be made by sacrifice, typical of the atonement of Christ, who by himself has purged our sins. The design of these several laws concerning uncleanness by issues, was to set forth the filthiness of sin arising from the corruption of human nature; particularly the pollution of fleshly lusts, and the necessity of purification from them by the grace of God, and blood of Christ, and of holiness of heart and life, in order to a near approach to God, particularly in public worship, as the next words suggest.
