Detailing the anti-Semitic slur about proverbial saver (1,6,2,4)
I believe the answer is:
a stitch in time
'proverbial saver' is the definition.
(I've seen this in another clue)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for a stitch in time that I've seen before include "prompt repair" , "Something that proverbially saves nine" , "Nine saver?" .)
