Bible book detailed in a movement that's tasteful (9)
I believe the answer is:
aesthetic
'tasteful' is the definition.
(similar in meaning)
'bible book detailed in a movement' is the wordplay.
'bible book' becomes 'esther' (Esther is a book of the Old Testament).
'detailed' means to remove the last letter (the word must be end-less or 'de-tailed').
'in' is an insertion indicator.
'movement' becomes 'tic' (an involuntary physical movement).
'esther' with its final letter taken away is 'esthe'.
'a'+'tic'='atic'
'esthe' placed into 'atic' is 'AESTHETIC'.
'that's' is the link.
(Other definitions for aesthetic that I've seen before include "Of pleasing appearance" , "Concerned with the appreciation of beauty" .)
