RE: It is necessary to examine closely the terms of the original and what their range of meaning might have been to those who used them.
OK, I’m all ears, what are the range of meanings of the word : “forever and ever?”
Hear is the English definition of the word — forever:
https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=meaning%3A%20forever
“for all future time; for always.”
“continually”
“lasting or permanent”
What other range of meaning are there?
