The narrative changes gears considerably in the last two chapters of Joshua. 

We get "the years passed" and mention that "Joshua was now very old", and it is clearly a conclusion to the story of this mighty leader. It is interesting to notice the ways in which Joshua himself can't easily see how emphases might change as God continues to lead his people. This entirely normal human limitation is perhaps just as true of any generation, and we are intrigued by the way Old Testament history proves God is more gracious than Joshua imagined.
