For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age... Eph 6:12f

Take up the whole armor of God

For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places. Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand. Ephesians 6:12-13
