'Kingly' in the Bible

Then another sign [of warning] was seen in heaven: behold, a great fiery red dragon (Satan) with seven heads and ten horns, and on his heads were seven royal crowns (diadems).

And he took up a position upon the sands of the sea-shore. Then I saw a Wild Beast coming up out of the sea, and he had ten horns and seven heads. On his horns were ten kingly crowns, and inscribed on his heads were names full of blasphemy.

And the woman whom you have seen is the great city which has kingly power over the kings of the earth."

And I heard as a voice of a great crowd, and as a voice of many waters, and as a voice of strong thunders, saying, Hallelujah, for the Lord our God the Almighty has taken to himself kingly power.

His eyes are a flame of fire, and on His head are many royal crowns; and He has a name inscribed [on Him] which no one knows or understands except Himself.
