Principalities
are,


Chiefs, heads, royalty,
rulers, or supreme powers,
whether heavenly or earthly.
...And to make all men see what is the fellowship
of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:  To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God, According to the eternal purpose which He purposed in Christ Jesus our Lord...

Ephesians 3:9-10
...Put them in mind to be subject to principalities and powers, to obey magistrates,
to be ready to every good work,
To speak evil of no man, to be no brawlers,
but gentle, showing all meekness
unto all men.

Titus 3:1-2
