How is Sefer Yeshaya structured? It doesn't seem to be chronological. The book seems to start with chapter 6 which presumably took place during the reign of Uzziah. Rashi says chapter 1 started after the Northern Kingdom was destroyed.
One structure I saw from a teacher of Tanach is as follows:
In terms of general structure:
Perakim 1-39 are rebuke.
Perakim 40-66 are comfort.
One can then look at the details of the first half of prophecies:
Perakim 1 and 11 are actually not rebuke, and are about the end of days. Therefore, the Malbim proposes:
- If you do not repent, you will have problems
- Look how great it can be if you repent! (Perek 2)
- The downfall of the North followed by Assyria moving into the South = big problems and destruction.
- It's a lost cause, so discuss the furture again rather than rebuke. (Perek 11)
The Malbim further mentions that a discussion of the end of days and "utopia" is only relevant when bnei yisrael are in trouble.
Lastly, I vaguely remember that Perek 2 is about the end of days that could have come right then if we were good, ie it's an actual option if we repent. However Perek 11 is now only a glimpse of what is destined to come at some point, but not an immediate choice.
