The Chaldeans answered, There is not a man upon the earth that can show the king's matter Here the wise men are driven to acknowledge their inability, and their excuse is, that they could indeed tell what dreams signified, if the dreams were told them; but as to telling what a person had dreamed, it was above the power of any art or knowledge but that of the gods, who knew all things. But this reasoning was weak, and showed the king's accusation to be just, namely, that they had prepared lying and corrupt words to speak before him; or, that their business and skill were only to invent or affix such interpretations of dreams as they thought suitable, without having any real knowledge at all of future things.

Daniel 2:10-11
10 The Chaldeans answered before the king, and said, There is not a man upon the earth that can shew the king's matter: therefore there is no king, lord, nor ruler, that asked such things at any magician, or astrologer, or Chaldean.
11 And it is a rare thing that the king requireth, and there is none other that can shew it before the king, except the gods, whose dwelling is not with flesh.
