Daniel 5:29

Then commanded Belshazzar. The king fulfilled the promise he had made to Daniel, although Daniel clearly indicated that he was not interested in the proffered honors. Because of Belshazzar’s drunken condition it may not have been possible to deter him from his course. Some have objected that the dignity of being third ruler was not possible, because, according to v. 30, Belshazzar was slain that very night. The objection is based on the supposition that the proclamation was publicly made in the streets of the city. But the words do not necessitate such a supposition. The proclamation may have been made only before the notables assembled in the palace. It could not become effective because of succeeding events.
