I think you must be right, or the two spellings would not occur in such similar contexts.

select 
    substring(cmp.sim::text,1,5) sim
  , k1.text || chr(10) || 
    k2.text || chr(10)     as "txt1 vs txt2"
  , k1.book || ':' || k1.chapter || ':' || k1.verse || chr(10) ||
    k2.book || ':' || k2.chapter || ':' || k2.verse      "location"
from kjv_simil_0_25 cmp 
join kjv k1 on id1=k1.id
join kjv k2 on id2=k2.id
where sim >= 0.5
  and k1.text ~ 'Ashchenaz|Ashkenaz'
  and k2.text ~ 'Ashchenaz|Ashkenaz'
order by 1 desc ;
