15:18 A man - Or, The man, that had such an issue, which is plainly to be understood out of the whole context. For though in some special cases relating to the worship of God, men were to forbear the use of the marriage - bed, yet to affirm that the use of it in other cases did generally defile the persons, and make them unclean till even, is contrary to the whole current of scripture, which affirms the marriage - bed to be undefiled, Heb 13:4, to the practice of the Jews, which is a good comment upon their own laws, and to the light of nature and reason.
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.
