A job for the French disciples (8)
I believe the answer is:
apostles
'disciples' is the definition.
(I know this)
'a job for the french' is the wordplay.
'job' becomes 'post' (post is a kind of job).
'for' means one lot of letters go next to another.
'the french' becomes 'les' ('the' in French).
'a'+'post'+'les'='APOSTLES'
(Other definitions for apostles that I've seen before include "Disciples chosen by Jesus" , "Christ sent twelve of them to preach the gospel" , "Followers of Jesus" , "Jesus's disciples" , "preachers" .)
