That man prepares book (7)
I believe the answer is:
hebrews
'book' is the definition.
(book of bible)
'that man prepares' is the wordplay.
'that man' becomes 'he' (pronoun for a man).
'prepares' becomes 'brews'.
'he'+'brews'='HEBREWS'
(Other definitions for hebrews that I've seen before include "Memers of an ancient Semitic peoples" , "book before James" , "Jews" , "An NT epistle" .)
