Ephesians 6:10 - Finally, my brethren, be strong in the Lord, and in the power of his might.

Ephesians 6:11 - Put on the whole armor of God, that ye may be able to stand against the wiles of the devil.

Ephesians 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.
