Isaiah

Isaiah is a preexilic book of prophecies warning Israel about the coming conquest of Babylon and guiding them through their struggles. It contains some of the most beautiful scriptures in the Bible, which no one has ever actually heard because the book is just so damn long.

It was one of the most significant finds among the Wadi Qumran scrolls, proving once and for all that the entire book could indeed fit on a single page.

Structure
Isaiah is a prophetic book that can be divided into three distinct parts. The first warns Israel about the coming judgement while the next two parts tell of the return from exile and the future realization of a new Earth. The entire book is attributed to Isaiah Ben Amoz but modern scholars have seen the latter two parts as being a later Isaiah because it presupposes the return from exile, and also because scholars don't see how a prophet could somehow prophesy a future event.

Contents and interpretation
Isaiah's prophecy is 90% concerned with how Israel and it's surrounding nations are going to get utterly brutalized by Babylon, but you probably prefer that verse about the wings of eagles.

Isaiah has long been a controversial book considering how peaceful it was to the original readers and how violent it is to modern ones.

Jesus prophecy
Several passages throughout Isaiah, most notably chapter 53, use strong Christological terminology. As such Christians have long argued that Isaiah is the most unequivocal prefiguring of Jesus in the Old Testament on the grounds of specific references to the virgin birth (7:14), a divine son (9:6), sin-bearing (53:4,5,10,12), innocent sacrifice (53:5,7,10,12), being buried in a rich man's tomb (53:9), and divine appointment (61:1); while critics have taken the longstanding Jewish opinion of "No it isn't."

Guide to reading
Due to the book's extreme length, experts recommend the popular strategy of not reading it but saying you did.
