What did Job say that was so different from the 3 friends he argued with? 

How could Eliphaz be so stupid? The solution for Job’s enemies may be the same as the solution for arguments in the 21st century.: 

Some people might brush off a night vision as a bad dream. Not this King.

Particular comparisons between the parable of the Mustard seed and King Nebuchadnezzar's first dream. Rock => Seed; Mountain => Mustard Plant; Statue => Other Plants.

Nebuchadnezzar had a question. Hundreds of years later, Jesus had a question.  The questions aren't the same, but they are related.
