'Kingdoms of the Earth' in the Bible

Hezekiah prayed before the LORD, and said, "The LORD, the God of Israel, who sit above the cherubim, you are the God, even you alone, of all the kingdoms of the earth. You have made heaven and earth.

Now therefore, the LORD our God, save us, I beg you, out of his hand, that all the kingdoms of the earth may know that you, LORD, are God alone."
