The devil/satan is called the prince of the air.
        Ephesians 2:2  Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience

        Prince speaks of the exalted position of his 
        rulership.
        Power speaks of the area of his rulership, above 
        and around the earth.
