It’s fun to look at scriptures.lds.org page for 2 Nephi, with all of the headings (original and added) all in a row. It gives a sense of what the message of the book is and how the different parts build on each other.
For example, if Nephi is concerned with making the Abrahamic Covenant known to his descendants, and he does this by quoting Isaiah, then it’s helpful to see, even at a glance, what themes and topics Isaiah talks about.
I get the idea that a gathering and a restoring of Israel is primary here. But how is that accomplished? That’s the sort of question I have in mind. (That I’m only starting to think about.)
On a related note, it was helpful to see the sermon of Jacob summarized chapter by chapter. He reads Isaiah, then talks about atonement/resurrection, and then back to the Jews relationship to Christ and the fulfillment of the Covenant. Why detour to the atonement in chapter 9? Or rather, I should probably realize it’s not a detour at all and crucial to his conversation about the Abrahamic Covenant.
Again, just leads in my short study time this morning, but at it’s fun to even see a few leads.
