'Chief' in the Bible

saying, "Belteshazzar, chief of the magicians, in whom I know there to be a spirit of the holy gods and whom no mystery baffles, consider my dream that I saw and set forth its interpretation!

There is a man in your kingdom who has within him a spirit of the holy gods. In the days of your father, he proved to have insight, discernment, and wisdom like that of the gods. King Nebuchadnezzar your father appointed him chief of the magicians, astrologers, wise men, and diviners.
