The devil said to him, "I will give you all this authority, and their glory, for it has been delivered to me; and I give it to whomever I want.

 Jesus' authority was something quite new. When the Rabbis taught they supported every statement with quotations. They always said, "There is a saying that . . ." "Rabbi so and so said that ..."

He needed no authorities to buttress him; his was not a delegated authority; he was authority incarnate. Here was a man who spoke as one who knew.
