Jesus' glory is revealed more fully before some disciples, which convinces them and makes them wonder when Elijah came.
Jesus casts out a demon that His disciples couldn't. He obviously didn't give them ALL His power.
Jesus rather cynically points out that rulers exempt their families but tax their people; He provides the tax for Peter and Himself miraculously.
How this is about Jesus
Jesus is the Son of the King, glorious and... exempt from paying taxes since He agreed to the heaviest tax penalty and audit of all time.
