'Royal' in the Bible

After Saul had secured his royal position over Israel, he fought against all their enemies on all sides -- the Moabites, Ammonites, Edomites, the kings of Zobah, and the Philistines. In every direction that he turned he was victorious.

He also took off his [royal] robes [and armor] and prophesied before Samuel and lay down naked all that day and night. So they say, “Is Saul also among the prophets?”

And David said unto Achish, If I have now found grace in thine eyes, let them give me a place in some town in the country, that I may dwell there: for why should thy servant dwell in the royal city with thee?
