'Kingdoms' in the Bible

And Hezekiah prayed before the LORD, and said, O LORD God of Israel, which dwellest between the cherubims, thou art the God, even thou alone, of all the kingdoms of the earth; thou hast made heaven and earth.

Now therefore, O LORD our God, I beseech thee, save thou us out of his hand, that all the kingdoms of the earth may know that thou art the LORD God, even thou only.
