(23) And if it be on her bed.--Better, and if any object be on her bed, that is, if anything happen to lie on her bed.

When he toucheth it.--Rather, if he toucheth it. Whilst the former two verses declare that if any one touches the bed itself, or the thing on which she sat, he contracts such a degree of defilement that he must wash his clothes, bathe his whole body, and remain in a state of pollution till sundown, the verse before us enacts that if he happens to touch any vessel, garment, or any other objects which are lying on the defiling bed or seat in question, he has only to remain unclean till sundown, without having to wash his garments. The defilement in this case is not primary, but secondary. It is no more the bed or seat which defiled by direct contact, but an object which the defiled bed or seat had defiled, the pollution in this case being indirect.

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 if it be on her bed, or on anything whereon she sitteth,.... That is, if any person or thing should be upon her bed or seat; a vessel on her bed, or a vessel upon a vessel, as Aben Ezra expresses it:

when he toucheth it; that person or thing that should be on her bed or seat, as well as touch her bed or seat:

shall be unclean until the even; in a ceremonial sense; so defiling was a woman in such circumstances, and to whom the Scriptures often compare unclean persons and things: and Pliny (i) speaks of menstrues as very infectious, or worse, to various creatures and things, in a natural way.
