For this cause the king was angry, and very furious,.... Not only because they could not tell his dream, and the interpretation of it; but because they represented him as requiring a thing unreasonable and impossible, which had never been done by any potentate but himself, and could never be answered but by the gods: this threw him into an excess of wrath and fury; which in those tyrannical and despotic princes was exceeding great and terrible: and commanded to destroy all the wise men of Babylon; not only those that were now in his presence, but all others; concluding from this instance that they were an useless set of men, yea, deceivers and impostors.
