Numbers 16:21; 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.
