We treated Babylon medically, but she would not heal.
Let us forsake her, and let each move to his country.
(Jeremiah 28:9, Septuagint)

In prophecy the future is well joined to the past, whereby both are signified.
Since things which are prophesied of as yet to come in reference to time are future;
but in reference to the knowledge of those who prophesy they are already viewed as done. 
St. Augustine, Explanation of the Psalms
