I agree the NWT is quite hilarious in its earlier iterations, I do not have a 2013 Copy to compare.
On the matter of "the true god" in the O.T they accidently end up underlining that the Israelites early on were not monotheistic, at best they were henotheistic, not something the org. would wish to be highlighted !
I still find the Translation throughout to be clunky and difficult to the modern ear, but they have, perhaps wisely, erred on the side of accuracy rather than readability !
I always enjoy your Posts ! have you read the Paper that Doug Mason posted on his Nehemiah and Ezra Thread ? entitled " Persia and Creation of Judaism" , it is VERY enlightening as to when the Hebrew Bible was written, and by whom, not that it is all brand new info. but it sheds more light on it, and expands what we should think of as myth in the O.T.
