Editing Book of Isaiah (section)

== Structure ==
General scholarly consensus through most of the 20th century saw three separate collections of oracles in the book of Isaiah.{{sfn| Petersen| 2002| pp = 47–48}} A typical outline based on this understanding of the book sees its underlying structure in terms of the identification of historical figures who might have been their authors:{{sfn|Sweeney|1998|p= 78}}
* [[Isaiah 1|1]]–[[Isaiah 39|39]]: Proto-Isaiah, containing the words of the original [[Isaiah]];
* [[Isaiah 40|40]]–[[Isaiah 55|55]]: Deutero-Isaiah, the work of an anonymous Exilic author;
* [[Isaiah 56|56]]–[[Isaiah 66|66]]: Trito-Isaiah, an anthology of about twelve passages.{{sfn|Soggin|1989|p= 394}}

While one part of the general consensus still holds, this perception of Isaiah as made up of three rather distinct sections underwent a radical challenge in the last quarter of the 20th century.{{sfn|Petersen|2002|pp=47–48}} The newer approach looks at the book in terms of its literary and formal characteristics, rather than authors, and sees in it a two-part structure divided between chapters 33 and 34:{{sfn|Sweeney|1998|pp=78–79}}
* [[Isaiah 1|1]]–[[Isaiah 33|33]]: Warnings of judgment and promises of subsequent restoration for Jerusalem, Judah and the nations;
* [[Isaiah 34|34]]–[[Isaiah 66|66]]: Judgment has already taken place and restoration is at hand.
