'Signs' in the Bible

Then Daniel said in answer to the king, No wise men, or users of secret arts, or wonder-workers, or readers of signs, are able to make clear to the king the secret he is searching for;

I thought it good to shew the signs and wonders that the high God hath wrought toward me.

How great are his signs! and how mighty are his wonders! his kingdom is an everlasting kingdom, and his dominion is from generation to generation.

Then the wonder-workers, the users of secret arts, the Chaldaeans, and the readers of signs came in to me: and I put the dream before them but they did not make clear the sense of it to me.

The king, crying out with a loud voice, said that the users of secret arts, the Chaldaeans, and the readers of signs, were to be sent for. The king made answer and said to the wise men of Babylon, Whoever is able to make out this writing, and make clear to me the sense of it, will be clothed in purple and have a chain of gold round his neck, and will be a ruler of high authority in the kingdom.

There is a man in your kingdom in whom is the spirit of the holy gods; and in the days of your father, light and reason like the wisdom of the gods were seen in him: and King Nebuchadnezzar, your father, made him master of the wonder-workers, and the users of secret arts, and the Chaldaeans, and the readers of signs;

He delivereth and rescueth, and he worketh signs and wonders in heaven and in earth, who hath delivered Daniel from the power of the lions.
