Clever as Biblical victim said to be (4)
I believe the answer is:
able
'clever' is the definition.
(able can mean skilled or talented)
'biblical victim said to be' is the wordplay.
'biblical victim' becomes 'abel' (I've seen this in another clue).
'said to be' indicates a 'sounds like' (homophone) clue.
'abel' sounds like 'ABLE'.
'as' acts as a link.
(Other definitions for able that I've seen before include "Fully competent" , "Of high proficiency" , "Capable or proficient" , "showing talent" , "- -bodied; - seaman" .)
