In Alma 17 we read of Alma’s reunion with the sons of Mosiah. The next 10 chapters of the Book of Mormon are a flashback to what happened to each of them (Alma 17:5 to 27:15).
What is particularly impressive is that Alma 20:30 to Alma 21:14 is actually a flashback within the flashback. Alma 20:28-30 tells the story of Ammon rescuing Aaron and others from the land of Middoni. Then Aaron’s record of his own preaching, imprisonment, and rescue is laid out in Alma 21:1–17.
How did Joseph Smith manage to dictate this part without getting confused? Why would a first-time author like Joseph make the content so unnecessarily complex?
