And the devil took (Jesus) up and showed him all the kingdoms of the world in a moment of time, and said to him, ‘to you I will give all this authority and their glory, for it has been delivered to me, and I give it to whom I will.  If you, then, will worship me, it will all be yours.’  (Luke 4:5-7)

‘Authority’ is ἐξουσία exousia and it means licensed power, the right to act, to have charge of, or dominion over.
