You are mistaken for there are numerous sources that prove the correct interpretation of Jeremiah and they are Ezra, Daniel, Zechariah and Josephus. All of these souces refer to Jeremiah's propnecy of the seventy years and the collectively demonstrate that the seventy years was aperiod of desolation, exile and servitude to Babylon.
In reference to your second question regarding verses 12-14 these words refer to Babylon the city, its ruler and the land of Chaldea. This propnecy relates to the fate of this nation both ot its immediate Fall in 539 BCE and its eventual devastation in the straits of times. The prophecy began its fulfillment after 539 BCE or to be more technically correct after 537 BCE when the seventy years had been fulfilled.
