Numbers 16:30-33

But suppose the LORD does something that has never been done before. For example, what if a huge crack appears in the ground, and these men and their families fall into it and are buried alive, together with everything they own? Then you will know they have turned their backs on the LORD!” As soon as Moses said this, the ground under the men opened up and swallowed them alive, together with their families and everything they owned. Then the ground closed back up, and they were gone.
