Prophet's body brought back (4)
I believe the answer is:
amos
'prophet's' is the definition.
(biblical prophet)
'body brought back' is the wordplay.
'body' becomes 'soma' (soma is a kind of body).
'brought back' says the letters should be written in reverse.
'soma' back-to-front is 'AMOS'.
(Other definitions for amos that I've seen before include "American wild dog" , "30th OT book" , "Prophet in the Bible" , "Old Testament book" , "Hebrew prophet" .)
