'God of Heaven' in the Bible

that they would seek mercy from the God of heaven concerning this secret; that Daniel and his companions should not perish with the rest of the wise men of Babylon.

Then was the secret revealed to Daniel in a vision of the night. Then Daniel blessed the God of heaven.

You, O king, are king of kings, to whom the God of heaven has given the kingdom, the power, and the strength, and the glory;

In the days of those kings shall the God of heaven set up a kingdom which shall never be destroyed, nor shall its sovereignty be left to another people; but it shall break in pieces and consume all those kingdoms, and it shall stand forever.
