(30) And the priest shall offer.--Exactly in the same manner as described in Leviticus 15:15.

15:1-33 Laws concerning ceremonial uncleanness. - We need not be curious in explaining these laws; but have reason to be thankful that we need fear no defilement, except that of sin, nor need ceremonial and burdensome purifications. These laws remind us that God sees all things, even those which escape the notice of men. The great gospel duties of faith and repentance are here signified, and the great gospel privileges of the application of Christ's blood to our souls for our justification, and his grace for our sanctification.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.
