Biblical barterer (4)
I believe the answer is:
esau
'biblical barterer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for esau that I've seen before include "wronged brother" , "Biblical twin to Jacob" , "Biblical brother to Jacob" , "Jacob's brother (OT)" , "Hairy brother to Jacob in Bible" .)
