Biblical son getting some stick, we hear (4)
I believe the answer is:
cain
'biblical son' is the definition.
(son of Adam)
'some stick we hear' is the wordplay.
'some stick' becomes 'cane' (cane is a kind of stick).
'we hear' shows a homophone (sound like).
'cane' sounds like 'CAIN'.
'getting' acts as a link.
(Other definitions for cain that I've seen before include "Slayer of Abel" , "First murderer reported in the Bible" , "Eve's firstborn" , "Eldest son of Adam, Eve" , "The first known murderer" .)
