'Royal' in the Bible

So Jesus came again to Cana of Galilee, where He had turned the water into wine. And there was a certain royal official whose son was sick in Capernaum.

Jesus replied, “My kingdom is not of this world [nor does it have its origin in this world]. If My kingdom were of this world, My servants would be fighting [hard] to keep Me from being handed over to the Jews; but as it is, My kingdom is not of this world.”
