'God of Heaven' in the Bible

So that they might make a request for the mercy of the God of heaven in the question of this secret; so that Daniel and his friends might not come to destruction with the rest of the wise men of Babylon.

Then the secret was made clear to Daniel in a vision of the night. And Daniel gave blessing to the God of heaven.

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

And in the days of those kings, the God of heaven will put up a kingdom which will never come to destruction, and its power will never be given into the hands of another people, and all these kingdoms will be broken and overcome by it, but it will keep its place for ever.
