"Beware __ anyone cheat you": Colossians (4)

I believe the answer is:

lest

(Other definitions for lest that I've seen before include "For fear that (something happens)" , "To avoid the risk that - let's do it" , "For fear that (something should happen)" , "In case" , "In order not to, to avoid the risk that" .)

I've seen this clue in the Newsday.
