'Diviners' in the Bible

So the king gave orders to summon diviners, enchanters, sorcerers, and Chaldeans to reveal to the king what he had dreamed. When they came and stood before him,

"None of the advisors, enchanters, diviners, or astrologers can explain the secret that the king has requested to be made known. But there is a God in heaven who reveals secrets, and he is making known to King Nebuchadnezzar what will happen in the latter days.

Then the diviners, enchanters, Chaldeans, and astrologers came in, and I told them the dream. But they could not reveal its interpretation to me.

"Belteshazzar, chief of the diviners, since I know that the spirit of the holy gods is within you, and no mystery too difficult for you, explain to me the vision of my dream that I saw, along with its interpretation.
