A foreteller of the future by astrology.
Therefore made I a decree to bring in all the wise men of Babylon before me, that they might make known unto me the interpretation of the dream. Then came in the magicians, the astrologers, the Chaldeans, and the SOOTHSAYERS: and I told the dream before them; but they did not make known unto me the interpretation thereof. ( Daniel 4:6-7 )
