Bring up Eve's son and cause a commotion (5,4)
I believe the answer is:
raise cain
'cause a commotion' is the definition.
(I've seen this before)
'bring up eve's son' is the wordplay.
'bring up' becomes 'raise' (as in bringing up children).
'eve's son' becomes 'cain' (biblical figure).
'raise'+'cain'='RAISE CAIN'
'and' acts as a link.
(Other definitions for raise cain that I've seen before include "cause trouble" , "create a disturbance" , "Make a lot of noise (in anger)" , "as Adam and Eve did" , "Create an unholy row - elevate murderer" .)
