Charles Ellicott Commentary Daniel 2:48

"Then the king made Daniel great, and gave him many great gifts, and made him to rule over the whole province of Babylon, and to be chief governor over all the wise men of Babylon." — Daniel 2:48 (ASV)

The Province. According to Daniel 3:2, the Babylonian empire consisted of several provinces, each of which had its own ruler or Shilton. Daniel became ruler of this one province of Babylon. What the other office was to which he was advanced may possibly be explained when further discoveries have been made. Until now it has been inexplicable.
