Person who digs up scripture about deity (7)
I believe the answer is:
minerva
'deity' is the definition.
(Minerva is an example)
'person who digs up scripture' is the wordplay.
'person who digs' becomes 'miner' (miners dig into the ground).
'up scripture' becomes 'va' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'miner'+'va'='MINERVA'
'about' acts as a link.
(Other definitions for minerva that I've seen before include "Divine female" , "female of great wisdom" , "deity of wisdom" , "Roman goddess of learning" , "Roman counterpart of Athene" .)
