The second Asaf collection paints a depressing picture of the destruction of the Temple, the exile of the Jews and the victory of their enemies. How could these mizmorim have been put to music and even be called songs?
The second Asaf collection A2 (73-83) remembers King David (72) and the history of the Jewish people in order to face the destruction and the exile. Influenced by Megilat Eicha and the prophet Isaiah, Asaf builds new hope for the future as reflected in Books IV and V.
