'Kings' in the Bible

But what went ye out to see? a man clothed in soft raiment? Behold, they that are gorgeously apparelled, and live delicately, are in kings courts.

for I say unto you, that many prophets and kings desired to see the things which ye see, and saw them not; and to hear the things which ye hear, and heard them not.

But before all these things, they shall lay their hands on you, and shall persecute you, delivering you up to the synagogues and prisons, bringing you before kings and governors for my name's sake.

And he said unto them, The kings of the Gentiles have lordship over them; and they that have authority over them are called Benefactors.
