'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 powers in heavenly places might be known by the church the manifold wisdom of God,

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.
