Biblical hunter (6)
I believe the answer is:
nimrod
'biblical hunter' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nimrod that I've seen before include "OT hunter" , "Might hunter of Genesis" , "One of Elgar's Enigma Variations" , "Old hunter" , "Best-known of Elgar's Enigma Variations" .)
