Biblical Exegesis is a veritable industry. But what it all boils down to is the opinion of the exegete.
What JW's fail to realise is that their leaders, the G.B and those advising the G.B, do not deserve the title of Exegete. They are woefully ignorant about the various writings that make up the "Bible" (the clue is in the name, it is a Library, not a book with a theme).
Their book "What does the Bible really Teach", by its Title, illustrates their ignorant attitude, the Bible teaches nothing, it is men who teach their particular brand of nonsense, and claim it is "Bible-based".
Why should the opinion of any man weigh more than another as to what the writer was saying ? well, true Scholars, familiar with the original languages, and with other literature contemporary with the book under discussion, must be better equipped than you or I to venture a valid opinion, but the G.B and their Writers ?
Nah, they know no more than you or I, and precious little more than the R&F JW's they feed their nonsense to.
