'Royal' in the Bible

And Solomon planned to build a house for the name of Yahweh and a {royal palace for himself}.

Then Huram said, "Blessed be Yahweh, the God of Israel, who has made the heavens and the earth, who has given to King David a wise son knowing discretion and understanding, who will build for Yahweh a house and a royal palace for himself.

Now [when] Athaliah the mother of Ahaziah saw that her son [was] dead, she arose and murdered all the {royal descendants} of the house of Judah.
