He has to make beer for an Israelite (6)
I believe the answer is:
hebrew
'for an israelite' is the definition.
(I've seen this in another clue)
'he has to make beer' is the wordplay.
'has' is a charade indicator (letters next to each other).
'to make beer' becomes 'brew' (I've seen this before).
'he'+'brew'='HEBREW'
(Other definitions for hebrew that I've seen before include "Tongue" , "Jewish language" , "Language of ancient Palestine, still used in Israel" , "Ancient Semitic language, used in modern version in Israel" , "Middle Eastern language" .)
