'Nobles' in the Bible

In the third year of his reign, he made a feast unto all his princes and his servants; the power of Persia and Media, the nobles and princes of the provinces, being before him:

And let the clothing and the horse be given {to the man} by the officials of the king's nobles; let them cloth the man whom the king wishes to honor, and let him ride on his horse through the public square of the city, and let them proclaim before him, 'Thus, it will be done for the man whom the king wishes to honor.'"
