Daniel 5:30 - Clarke's commentary and critical notes on the Bible

In that night was Belshazzar the king of the Chaldeans slain. In that night was Belshazzar - slain - Xenophon says, he was dispatched by two lords, Gadatas and Gobrias, who went over to Cyrus, to avenge themselves of certain wrongs which Belshazzar had done them. We have already seen that Cyrus entered the city by the bed of the Euphrates, which he had emptied, by cutting a channel for the waters, and directing them into the marshy country.
