Then came in the magicians, the astrologers, the Chaldeans,
and the soothsayers (See Gill on Daniel 2:2), and I told the dream before them, but they did not make known unto
me the interpretation thereof;
because they could not; before they pretended, if the dream was told, they could give the interpretation of it; but now, though it was told, they could not do it; which shows the vanity of their art, the falsehood of their pretensions, and that they were but jugglers and impostors.
