Finally, my brethren, be strong in the Lord, and in the power of his might. [11] Put on the whole armour 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. [13] Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.

Ephesians 6:10-13 KJV
