The sense is easy: the translator is a traitor. The proverb is the near-rhyme. Move it, and the moral arrives while the music stops.
Italian proverb. Not pinned here to an author. The proverb is the joke, and the joke is the sound.

The joint
The proverb says that to translate is to betray. Plenty of languages can say that in a plain clause. Italian refuses the plain clause. Traduttore and traditore are two different verbs wearing the same suit. The ear holds them up as a pair and the mind supplies the accusation.
English “translator, traitor” is the best ordinary saving. The first syllables match, and then “traitor” ends early. Spanish traductor, traidor keeps the family resemblance. French traître is the right word and the wrong length. German Übersetzer, Verräter tells the truth and loses the music completely. Japanese 翻訳者は裏切り者 is crystal-clear and not a proverb. It is a sentence someone made in order to explain a proverb.
That last difference is the plate. A gloss can carry a moral. It cannot carry a form that was the moral’s only reason for being memorable. This site is full of glosses. The proverb is looking at them, unkindly, and not without cause.
Why this break matters to a reader
A reader given the sense has been told a theory of translation. A reader given the rhyme has been made to feel the theory click shut, like a latch. The click is the reason anyone repeats it. Without the click it is a warning label. With the click it is an accusation you can hear.
