Body of Jewish law (6)
I believe the answer is:
talmud
'body of jewish law' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for talmud that I've seen before include "Collection of Judaic laws and tradition" , "Sacred book of the Jewish faith" , "Body of Jewish civil and canon law" , "Body of Jewish laws and traditions" , "Sacred books of the Jews" .)
