'God of Heaven' in the Bible

that they would desire mercies of the God of heaven concerning this secret; that Daniel and his companions should nor perish with the rest of the wise men of Babylon.

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

Thou, O king, art king of kings, unto whom the God of heaven hath given the kingdom, the power, and the strength, and the glory;

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