This information brought to Joshua, is an evidence that there
   were those of the country, who knew the holes and fastnesses
   of it, that were in his interests.  And the care Joshua took
   to secure them there, as it is an instance of his policy and
   presence of mind, even in the heat of action; so, in the
   success of their project, it shews how they who think to hide
   themselves from God, not only deceive, but destroy themselves.
   Their refuge of lies will but bind them over to God's
   judgment.
