Regarding "The Dark Side of the Force"

The "spiritual wickedness" known anciently as
"principalities of darkness"

The Epistle of Paul, The Apostle to the
EPHESIANS

(King James version)

CHAPTER 6

Verses 10-12

10 - Finally, my brethren, be strong in the Lord, and in the power of his might.

11- Put on the whole armor of God, that ye may be able to stand against
      the wiles of the devil.

12 - For we wrestle not against flesh and blood, but against principalities,
      against powers, against the rulers of the darkness of this world,
      against spiritual wickedness in high places.
