'All the Kingdoms of the Earth' in the Bible

And Hezekiah prayed before LORD, and said, O LORD, the God of Israel, who sits [above] the cherubim, thou are the God, even thou alone, of all the kingdoms of the earth. Thou have made heaven and earth.

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