21 
   It should seem that Dathan and Abiram had set up a spacious
   tabernacle in the midst of the tents of their families, where
   they kept court, met in council, and hung out their flag of
   defiance against Moses; it is here called the tabernacle of
   Korah, Dathan, and Abiram.  There, as in the place of
   rendezvous, Dathan and Abiram stayed, when Korah and his
   friends went up to the tabernacle of the Lord, waiting the
   issue of their trial; but here we are told how they had their
   business done, before that trial was over.  God will take what
   method he pleases in his judgments.
