Daniel 2:48-49

48Then the king made Daniel an important officer. He also gave Daniel many valuable gifts. He gave Daniel authority to rule over the whole region of Babylon. Daniel also became the most important officer with authority over all the wise men in Babylon.

49Daniel asked the king to give important jobs to Shadrach, Meshach and Abednego. So the king gave them authority over the region of Babylon. But Daniel himself stayed in the king's palace.
