SEV Biblia, Chapter 15:23
Y si alguna cosa estuviere sobre la cama, o sobre la silla en que ella se hubiere sentado, el que lo tocare será inmundo hasta la tarde.
John Gill's Bible Commentary
Ver. 23. And if it [be] on [her] bed, or on anything whereon she sitteth , etc.] 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 speaks of menstrues as very infectious, or worse, to various creatures and things, in a natural way.
Matthew Henry Commentary
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, no need ceremonial and burdensome purifications. These laws remind us tha 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 ou souls for our justification, and his grace for our sanctification __________________________________________________________________
