Daniel 2:48

The king also promoted Daniel to be head man over the province of Babylon, and chief of the wise men. He evidently became the ruler in charge of this most important province (cf. Daniel 3:2). Normally this position would have gone to a Chaldean, a member of the "master race" of Babylonian society. The fact that Nebuchadnezzar gave it to a Jewish captive shows the tremendous respect that Daniel had earned with this revelation.
