'Royal' in the Bible

In the seventh month, Ishmael son of Nethaniah, son of Elishama, of the royal family and one of the king’s chief officers, came with 10 men to Gedaliah son of Ahikam at Mizpah. They ate a meal together there in Mizpah,

From the city he took a court official who had been appointed over the warriors; seven trusted royal aides found in the city; the secretary of the commander of the army, who enlisted the people of the land for military duty; and 60 men from the common people who were found within the city.
