'Ruler' in the Bible

The Chaldeans answered the king directly, "There's not a single man on earth who can do what the king has commanded. No king, lord, or ruler has ever asked such a thing from any diviner, enchanter, or Chaldean.

Then the king promoted Daniel to a high position and lavished many great gifts on him, including making him ruler over the entire province of Babylon and chief administrator over the advisors of Babylon.

The king cried out to bring in enchanters, Chaldeans, and astrologers. He announced to the advisors of Babylon, "Whoever can read this writing and tell me its meaning will be clothed in purple, have a gold chain placed around his neck, and will become the third highest ruler in the kingdom."

However, I've heard that you can provide meaning and interpretation, and that you can solve difficult problems. If you are able to read the writing and report its meaning, you will be clothed in purple, have a gold chain placed around your neck, and you will become the third highest ruler in the kingdom."

Then Belshazzar gave orders to clothe Daniel in purple, to place a chain of gold around his neck, and to proclaim him the third highest ruler of the kingdom.
