Bethlehem visitors (4)
I believe the answer is:
magi
'bethlehem visitors' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for magi that I've seen before include "Wise men who were guided by a star" , "Three Wise Men from the East" , "Sorcerers in ancient times" , "Christmas travellers" , "Wise men, visitors to Bethlehem" .)
