Job with Ezra, perhaps, entertaining gospel reader's friends? (9)

I believe the answer is:

bookmarks

'reader's friends?' is the definition.

'job with ezra perhaps entertaining gospel' is the wordplay.
'job with ezra perhaps' becomes 'books' (both are books of the Bible).
'entertaining' indicates putting letters inside.
'gospel' becomes 'mark' (Gospel of Mark).
'books' enclosing 'mark' is 'BOOKMARKS'.

I've seen this clue in The Telegraph.
