'Clothed in Purple' in the Bible

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.

And I have had news of you, that you have the power of making things clear, and of answering hard questions: now if you are able to make out the writing and give me the sense of it, you will be clothed in purple and have a gold chain round your neck and be a ruler of high authority in the kingdom.
