'Powers' in the Bible

wherein ye once walked according to the course of this world, according to the prince of the powers of the air, of the spirit that now worketh in the sons of disobedience;

to the intent that now unto the principalities and the powers in the heavenly places might be made known through the church the manifold wisdom of God,

For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world-rulers of this darkness, against the spiritual hosts of wickedness in the heavenly places .
