Then the king said to the wise men that knew the times
Astrologers, as Aben Ezra, that knew the fit time for doing anything; or that had knowledge of ancient times, historians, well read in history, and knew things that had happened similar to this:
for so was the king's manner towards all that knew law and judgment;
it was customary with him in any case of difficulty to have the opinion and advice of those that were expert in the law, and well understood right and wrong. These are called by Herodotus F20 the king's judges.
