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