'Royal' in the Bible

Joab fought against Rabbah of the Ammonites and captured the royal fortress.

When he shaved his head—he shaved it every year because his hair got so heavy for him that he had to shave it off—he would weigh the hair from his head and it would be five pounds according to the royal standard.

He threw stones at David and at all the royal servants, the people and the warriors on David’s right and left.
