There's some nice little mumbo-jumbo in this chapter about the New Jerusalem being established on the American continent, but I think the most interesting and most central verses here revolve around a meeting between Ether and Coriantumr.
Ether is essentially the only righteous person remaining in the Jaredite society, so he's apparently God's only option when it comes to selecting a prophet. Ether is staggeringly unpopular because of his preaching, so he's been living in a cave somewhere to avoid being beaten to death. But then God tells him to go and speak with the wicked king Coriantumr, so Ether dutifully relays the following prophecy: if Coriantumr repents, his life and his people's lives will be spared—but if he does not repent, Coriantumr will live to see his family and his entire society die, and he will be the last Jaredite left. Is it just me, or does this feel like the premise of a classical tragedy more than the premise of a book of scripture? I mean, if it had been three witches talking instead of just gloomy old Ether, it could have been Shakespeare.
But if we're following the pattern of a theatrical tragedy, it should come as no surprise that Coriantumr refuses to repent, tries to kill Ether, and then gets embroiled in an absurd, over-the-top war that fulfills the horrific prophecy. The next two chapters will go into painstaking detail about how all that comes to pass.
