O wise and learned monks of the perl (and particularly Christian persuasion), I seek wisdom on how to join all the elements of my array that I've referenced in a hash. I've parsed out sections of a text bible into a structure that I reference by book, chapter, and verse. I have tried to save my results to a hash that looks like: 
    ...
    my @saved_verses = @verses;
    $bible{$book}{$chapter}{'verses'} = \@saved_verses;
    @verses = (); # use again for next chapter

which I try to subsequently access to get either individual verses out, or to print all the verses in a particular chapter. 2 questions: 1. Is this the right way to copy off the @verses array so that I can reuse it when parsing the next chapter? or will I have the same problem with @saved_verses being replaced with the new verses? 2. When trying to access all the verses of a particular chapter, how do I join all the verses? (i.e. I want all the verses in Genesis Chapter 1) I seem to be able to access individual verses but can't seem to join on the array: 
    my $n = 0;
    $bible{$bookname}{$chapter}{'verses'}[$n];
    # but neither of the following seem to work
    join("\n\n",$bible{$bookname}{$chapter}{'verses'}[0..$#{$bible{"$b
+ookname"}{"$chapter"}{'verses'}}]);
    join("\n\n",$bible{$bookname}{$chapter}{'verses'});
    # I get instead ARRAY(0x[0-9]*) or Argument "" isn't numeric in ar
+ray element at ...

Hoping for a revelation on the proper procedures.
