Ruth the story and its grammar lessons

I wonder how much of the paradigm of the verb to be is in the story of Ruth. I will be looking. And I am almost ready to try and recompose myself to explore the grammar and the story - we only got as far as verse 6. There is conflict in my resources as to where sections begin and end. This is because there is overlap in the story markers.  Story markers are pairs of words or word forms that begin and end a section. Does verse 6 require that it be the beginning of a second section or the end of the first? Or is it both?

Ephratites/Ephrata (1:2, 4:11) and the children/child (1:5, 4:16) are a frame for the whole story, fields of Moab seem to me a frame for this first section. We can also see the usage of prepositions (or not) around place names.Verse 6 (per Campbell's analysis) also begins a new section for Naomi - divisible into two sections as I will show later, but carrying us all the way to the end of chapter 1. Fields of Moab and Bethlehem form the frame for the chapter as a whole.
