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

'book' is the definition.
(book of the Bible)

I don't understand how the rest of the clue works.

(Other definitions for daniel that I've seen before include "-- Barenboim, -- Boone" , "- Defoe, English writer" , "Make larger" , "He did time in a den of lions" , "Lions' den survivor" .)

I've seen this clue in The Times.
