Ephesians 6:10 - 12

6:10 ¶ Finally, my brethren, be strong in the Lord, and in the power of his might.
6:11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.
6:12 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.
