A divided populace in biblical land (4)
I believe the answer is:
moab
'biblical land' is the definition.
(I've seen this in another clue)
'a divided populace in' is the wordplay.
'divided populace' becomes 'mob' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'a' going inside 'mob' is 'MOAB'.
Can you help me to learn more?
(Other definitions for moab that I've seen before include "- is my Washpot, Stephen Fry autobiography" , "Part of Jordan" , "Land in OT" , "Biblical country" , "Biblical kingdom" .)
