Biblical figure sounds competent (4)
I believe the answer is:
abel
'biblical figure' is the definition.
(son of Adam and Eve)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for abel that I've seen before include "Biblical murder victim" , "Early murder victim" , "The first murderee?" , "Gardener's son" , "one killed early" .)
