Hairy biblical twin (4)
I believe the answer is:
esau
'hairy biblical twin' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for esau that I've seen before include "man tricked by kid brother" , "Isaac's hairy son" , "Twin brother of Jacob" , "Cunning hunter" , "Biblical character who sold birthright for pottage" .)
