Biblical renegade in a book before Biblical dancer? Not entirely (7)
I believe the answer is:
absalom
'biblical renegade' is the definition.
(son who rebelled against his father in the Bible)
'a book before biblical dancer? not entirely' is the wordplay.
'book' becomes 'b' (abbreviation for book).
'before' is a charade indicator (letters next to each other).
'biblical dancer?' becomes 'salome' (figure who famously dances in the Bible).
'not entirely' means to remove the last letter.
'salome' with its last letter taken away is 'salom'.
'a'+'b'+'salom'='ABSALOM'
'in' is the link.
(Other definitions for absalom that I've seen before include "King's rebellious son" , "Son of King David (OT)" , "David's third son (OT)" , "Son of King David (Bible)" , "King David's rebellious son" .)
