'God of Heaven' in the Bible

When I heard these words, I sat down and wept. I mourned for a number of days, fasting and praying before the God of heaven.

I said,Yahweh, the God of heaven, the great and awe-inspiring God who keeps His gracious covenant with those who love Him and keep His commands,

Then the king asked me, “What is your request?”So I prayed to the God of heaven

I gave them this reply, “The God of heaven is the One who will grant us success. We, His servants, will start building, but you have no share, right, or historic claim in Jerusalem.”
