'High God' in the Bible

Then Nebuchadnezzar came near the door of the burning fiery furnace. He answered and said, Shadrach, Meshach, and Abednego, servants of the Most High God, come forth and come here. Then Shadrach, Meshach, and Abednego, came forth from the middle of the fire.

It seemed good before me to declare the signs and wonders that the Most High God has done with me.

O king, the Most High God gave Nebuchadnezzar your father a kingdom, and majesty, and glory, and honor.

And he was driven from the sons of men. And his heart was made like the animals, and his dwelling was with the wild asses. They fed him with grass like oxen, and his body was wet with the dew of the heavens, until he knew that the Most High God rules in the kingdom of men, and that He appoints over it whomever He will.
