'Royal' in the Bible

And it came to pass in the seventh month, that Ishmael the son of Nethaniah the son of Elishama, of the royal seed, and one of the king's chief men, and ten men with him, came to Gedaliah the son of Ahikam unto Mizpah, and there they ate bread together, in Mizpah.

and say unto them, Thus saith Jehovah of hosts, the God of Israel: Behold, I will send and take Nebuchadrezzar the king of Babylon, my servant, and will set his throne upon these stones which I have hidden, and he shall spread his royal pavilion over them.
