Glad to hear that AndyP, then perhaps you might help me... I too have a full grid and know N, and how it flows, separately, both from the 7 superfluous words' synonyms, and from the extra letters in other clues. I also know the Biblical reference and much of where it is in the grid.
I can even see how it's begining to look as if it might be wanting form an appropriate shape in the grid. But for all that, I can neither finish that highlighting, nor for the life of me seehow I get the Biblical reference to amount to N cells?
If you can help me resolve those questions, I may be able to offer you some parsing in return - I think I have all that though of course having said so, I'm inevitably going to find I lack the essential bit you ask for...
