'High God' in the Bible

Then Nebuchadnezzar came near to the opening of the burning fiery furnace; he spoke and said, Shadrach, Meshach, and Abed-nego, ye servants of the Most High God, come forth, and come hither. Then Shadrach, Meshach, and Abed-nego came forth from the midst of the fire.

It hath seemed good unto me to declare the signs and wonders that the Most High God hath wrought toward me.

O thou king, the Most High God gave Nebuchadnezzar thy father the kingdom, and greatness, and glory, and majesty;

and he was driven from the sons of men, and his heart was made like the beasts, and his dwelling was with the wild asses; they fed him with grass like oxen, and his body was bathed with the dew of heaven; till he knew that the Most High God ruleth over the kingdom of men, and that he appointeth over it whomsoever he will.
