'High God' in the Bible

Upon this went Nebuchadnezzar unto the mouth of the hot burning oven: he spake also, and said, "O Shadrach, Meshach, and Abednego, ye servants of the high God: go forth, and come hither." And so Shadrach, Meshach, and Abednego went out of the fire.

I thought it good to show the tokens and marvelous works that the high God hath wrought upon me.
