When Nebuchadnezzar is troubled by his dreams, he summons:
“the magicians, the astrologers, the sorcerers and the Chaldeans” (Daniel 2.2).
These men are to:
“tell him his dreams” (Daniel 2.2).
The passage therefore brings together several categories of specialists around a single immediate function: to answer the sovereign’s demand concerning his dream.
Daniel 2.27 uses a comparable list when Daniel declares:
“The mystery that the king is asking about, neither the wise men, nor the astrologers, nor the magicians, nor the diviners can reveal to the king.”
The diversity of terms shows that, in the book’s representation, the royal court had several categories of specialized advisers.
