Wise men importing Bible version for barbarians (7)
I believe the answer is:
savages
'for barbarians' is the definition.
('savage' can be a synonym of 'barbarian')
'wise men importing bible version' is the wordplay.
'wise men' becomes 'sages' (I've seen this before).
'importing' means one lot of letters goes inside another.
'bible version' becomes 'AV' (Authorised Version of the Bible).
'sages' placed around 'av' is 'SAVAGES'.
(Other definitions for savages that I've seen before include "More than one brutal person" , "Barbarians" .)
