Sue a revolting brother of Jacob (4)
I believe the answer is:
esau
'brother of jacob' is the definition.
(I've seen this before)
'sue a revolting' is the wordplay.
'revolting' is an anagram indicator.
'sue'+'a'='suea'
'suea' anagrammed gives 'ESAU'.
(Other definitions for esau that I've seen before include "Jacob's brother (Gen.)" , "Twin brother of Jacob" , "Son of Isaac and Rebecca" , "Biblical brother to Jacob" , "scriptural character" .)
