Articles about border and the area around a Biblical region (10)

'biblical region' is the definition.
The definition suggests a singular noun which matches the answer.

'articles about border and the area around a' is the wordplay.
I cannot quite see how this works, but
'about' could be 'a' (abbreviation in Chambers) and 'a' is found in the answer.
'border' could be 'rim' (both can mean an edge) and 'rim' is located in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
'area' could be 'a' (maths abbreviation) and 'a' is found in the answer.
'a' is within the answer.
This may be the basis of the clue (or it may be nonsense).
