'God of Heaven' in the Bible

that they should beseech the God of heaven for grace in this secret, that Daniel and his fellows with others such as were wise in Babylon, perished not.

Then was the mystery showed unto Daniel in a vision by night. And Daniel praised the God of heaven.

O king, thou art a king of kings: For the God of heaven hath given thee a kingdom, riches, strength, and majesty:

In the days of these kings, shall the God of heaven set up an everlasting kingdom, which shall not perish, and his kingdom shall not be given over to another people. Yea, the same shall break and destroy all these kingdoms, but it shall endure forever.
