Prophet, priest, god (6)

I believe the answer is:

elijah

I'm a little stuck... Click here to teach me more about this clue!

'prophet' is the definition.
(I know that Elijah is a prophet)

'priest god' is the wordplay.
'priest' becomes 'eli' (biblical figure).
'god' becomes 'jah' (I am not sure about this - if you are sure you should believe this answer much more).
'eli'+'jah'='ELIJAH'

Can you help me to learn more?

(Other definitions for elijah that I've seen before include "Biblical prophet" , "Hebrew prophet in the time of Jezebel" , "Mendelssohn oratorio" , "O.T. prophet who disappeared in fiery chariot" , "Hebrew prophet who rebuked Ahab and Jezebel" .)

I've seen this clue in The Sunday Times and The Times.
