Daniel 3:2-3

Then Nebuchadnezzar sent to gather together the princes, &c. It would be very difficult, and perhaps impossible, at this distance of time, to ascertain the proper titles and offices of the several characters that are here mentioned, and certainly would answer no valuable end to any reader. It may be sufficient to observe, that it is probable only those were summoned to attend on this occasion who held places under the government. Thousands of others, no doubt, would be present, and, when present, were required to comply with the king's injunction respecting worshipping the image, though they had not been summoned. And they came and stood before the image They made their personal appearance, and showed themselves ready to perform the worship required of them.
