Biblical pariah (5)
I believe the answer is:
leper
'biblical pariah' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for leper that I've seen before include "Undesirable" , "Sufferer from dread disease, once made to wear bell" , "This person unwanted by society" , "Person shunned socially" , "Someone shunned" .)
