'God of Heaven' in the Bible

Daniel was seeking mercy, in order to ask about this mystery in the presence of the God of heaven, so that Daniel and his friends might not be executed along with the rest of the advisors of Babylon.

When the mystery was revealed to Daniel in a vision later that night, Daniel blessed the God of heaven

You, your majesty, king of kings to whom the God of heaven has given the kingdom, the power, the strength, and the glory,

"During the reigns of those kings, the God of heaven will set up a kingdom that will never be destroyed, nor its sovereignty left in the hands of another people. It will shatter and crush all of these kingdoms, and it will stand forever.
