'Royal' in the Bible

Jehu met the relatives of Ahaziah king of Judah and said, “Who are you?” They answered, “We are the relatives of Ahaziah; and we came down to greet the royal princes and the sons of the queen mother [Jezebel].”

When Athaliah the mother of Ahaziah [king of Judah] saw that her son was dead, she arose and destroyed all the royal offspring.

Then Eliakim the son of Hilkiah, who was in charge of the [royal] household, and Shebna the scribe and Joah the son of Asaph the secretary, came to Hezekiah with their clothes torn [in grief and despair] and told him what the Rabshakeh had said.

But in the seventh month Ishmael the son of Nethaniah, the son of Elishama, of the royal family [who had a claim to be governor], came with ten men and struck and killed Gedaliah and the Jews and the Chaldeans who were with him at Mizpah.
