'Clothed with Purple' in the Bible

Wherefore the king cried mightily, that they should bring him the charmers, Chaldeans, and the conjurers of devils. The king spake also to the wise men of Babylon, and said, "Whoso can read this writing, and show me the plain meaning thereof: shall be clothed with purple, have a chain of gold about his neck, and rule the third part of my kingdom."

Then heard I say, that thou can expound dark things, and declare hard doubts. Well then, if thou can read this writing, and show me the meaning thereof: thou shalt be clothed with purple, have a chain of gold about thy neck, and rule the third part of my kingdom."
