That said, in a really simple, structural level, there emerges a pattern. Namely, Iyyov's life starts out wonderful, the middle is filled with pain, angst, and suffering; but finally his previous, prosperous life is restored to something even better than before.
Does not this structure resemble the pattern of
1 Paradise [Gan Eden]
2 Paradise Lost [Geirush]
3 Paradise Regained? [Moshi'ach or Hashivenu?]
