E il re Nebukadnetsar mandò a radunare i satrapi, i prefetti e i governatori, i giudici, i tesorieri, i consiglieri, i magistrati e tutti i governanti delle province, perché venissero alla dedicazione della statua che il re Nebukadnetsar aveva innalzato.
Ibn Ezra
[Daniel 3:2] And Nebuchadnezzar... to gather (לְמִכְנַשׁ - l'michnash): To assemble (l'kabetz) and to bring together (ul'chaber). The satraps (אֲחַשְׁדַּרְפְּנַיָּא - achashdarpenaya) and those mentioned after them [the list of officials]: These are [like] seven levels [of administration] in the language of Ishmael [i.e., in Arabic administrative systems], but we do not know the [precise] meaning of counselors (אֲדַרְגָּזְרַיָּא - adargazraya) and those that come after them [i.e., treasurers, judges, officers]. And there was a sage in Spain who interpreted counselors (אֲדַרְגָּזְרַיָּא - adargazraya) as "mighty deciders" (adirei g'zerin - combining Hebrew/Aramaic roots a-d-r 'mighty' and g-z-r 'decree/decide'). But there is no need [for such speculation]. Therefore, we will leave them [uninterpreted], as it will not be beneficial [to guess].
Rashi
the judges, the treasurers, etc. They are all names of nations.
