'Royal' in the Bible

And the king {ordered} Ashpenaz, the commander of his court officials, to bring {some of the Israelites} from {the royal family} and from the lords,

{He asked} and said to Arioch, the royal official of the king, "{Why} is the decree from the king [so] severe?" Then Arioch explained the matter to Daniel.

At the end of twelve months he was walking on the [roof of] {the royal palace} of Babylon.

And the king answered and said, "Is this not the great Babylon which I have built as a royal palace by the strength of my own power, and for the glory of my own majesty?"

And those who eat of his royal rations will break him and his army will be overwhelmed, and many will fall, slain.
