'Clothed in Purple' in the Bible

The king called out loudly to summon the astrologers, wise men, and diviners. The king proclaimed to the wise men of Babylon that anyone who could read this inscription and disclose its interpretation would be clothed in purple and have a golden collar placed on his neck and be third ruler in the kingdom.

Then, on Belshazzar's orders, Daniel was clothed in purple, a golden collar was placed around his neck, and he was proclaimed third ruler in the kingdom.
