15:19 And if a woman - Heb. And a woman when she shall have an issue of blood, and her issue shalt be in her flesh, that is, in her secret parts, as flesh is taken, Lev 15:2. So it notes her monthly disease. Put apart - Not out of the camp, but from converse with her husband and others, and from access to the house of God. Seven days - For sometimes it continues so long; and it was decent to allow some time for purification after the ceasing of her issue. Whosoever toucheth her - Of grown persons. For the infant, to whom in that case she might give suck, was exempted from this pollution by the greater law of necessity, and by that antecedent law which required women to give suck to their own children.
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.
