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 4:7)
The king cried aloud to bring in the astrologers, the Chaldeans, and the soothsayers. And the king spake, and said to the wise men of Babylon, Whosoever shall read this writing, and show me the interpretation thereof, shall be clothed with scarlet, and have a chain of gold about his neck, and shall be the third ruler in the kingdom. (Daniel 5:7)
A sword is upon the Chaldeans, saith the Lord, and upon the inhabitants of Babylon, and upon her princes, and upon her wise men. (Jeremiah 50:35)
