Genesis 41:8

His spirit was troubled Because he was impressed with an idea that the dreams were supernatural, that something extraordinary was intended by them, and because he understood not their meaning, and dreaded the consequences. Compare Genesis 40:6; Daniel 2:1; and Matthew 27:19. He called for the magicians, who professed to discover secret and future things, either by consulting the stars, or by other superstitious practices; but if they ever did any thing of that kind, no doubt it was by the help of evil spirits. The wise men, distinguished from these, were employed, it seems, in the study of nature, and, by their great sagacity, often made happy conjectures respecting abstruse and future things. On what principles they interpreted dreams, does not appear. In this instance, however, they were puzzled, and the rules of their art failed them. But this was intended to render Joseph's interpretation of these dreams, by the Spirit of God, the more wonderful.
