In both cases, the twin passages are separated only by several chapters, and share the same narrator/speaker. Perhaps a modified version of this phenomenon, however, can also be found between different books and speakers in the Book of Mormon. As an example, I submit a comparison of Mosiah 3 (part of King Benjamin's address), and Alma 7 (the discourse of Alma the Younger to the people of Gideon). This juxtaposition is both more expansive than the previous examples, as it encompasses both chapters in their entirety, and less robust, as there are many elements that don't match at all. I believe the parallels that are present, however, merit consideration.
I'll begin my presenting both chapters side-by-side in their entirety, highlighting the similar elements of each with matching colors:
