There are interminable debates about this going one way and then the other, it seems that scholarly opinion has reached a consensus that lacking proof to the contrary, i.e the discovery of a very early N.T manuscript containing the Tetragrammaton, or some name derived from those four letters, we must presume it was never in the N.T
Some do err on the side of it perhaps being used in quotes by N.T from the Septuagint, but one scholar I read pointed out the difference between the actual words quoted and the ones found in the Septuagint as suggesting the N.T writer was remembering the words rather than copying them from a Manuscript that he had to hand.
Which means you would have to assume he heard the words read at a Synagogue, and would the reader utter the Name as he read, and cause a riot ? I doubt it.
It all boils down to the JW religion making much of this usage for their own aggrandisement, with no real basis for doing so, and really it simply DOESN'T MATTER !
