A common Latin
saying meaning "Let the Jew Apella
believe it; not I". The phrase means, roughly, tell it to someone else
, not me.
The reference is taken from the work Satires (book one, satire five) by ancient poet Horace. It is derived from a scene where people try to convince travellers of miracles happening at their shrines. The phrase is uttered to convey the disbelief and that they should tell their stories to someone else.
