'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 not perish with the rest of the wise men of Babylon.

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

Thou, O king, art a king of kings: for the God of heaven hath given thee a kingdom, power, and strength, and glory.

And in the days of these kings shall the God of heaven set up a kingdom, which shall never be destroyed: and the kingdom shall not be left to other people, but it shall break in pieces and consume all these kingdoms, and it shall stand for ever.
