MeAm Lo'ez

54:3  For the Jewish people shall break forth in number and shall inherit the entire Land - the nations which they had not hitherto conquered, the last three of the ten nations promised to Avraham.  But even this expansion will not be enough and they will "break forth in all directions," being forced to settle even desolate cities. 

They will also "break forth" from the limitations of nature and will be guided by G-d supernaturally.
