Biblical wise men (4)
I believe the answer is:
magi
'biblical wise men' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for magi that I've seen before include "Travellers in NT" , "Star witnesses" , "Wise men who were guided by a star" , "Caspar, Melchior and Balthasar" , "present suppliers" .)
