First they came for the Communists, and I didn't speak up, because I wasn't a Communist.

Then they came for the Jews, and I didn't speak up, because I wasn't a Jew.

Then they came for the Catholics, and I didn't speak up, because I was a Protestant.

Then they came for me, and by that time there was no one left to speak up for me.
by Rev. Martin Niemöller, 1945

Aquí la versión más común que se ha traducido al castellano:

"Cuando vinieron a buscar a los judíos,callé: yo no era judío.

Cuando vinieron a buscar a los comunistas,callé: yo no era comunista.

Cuando vinieron a buscar a los sindicalistas,callé: yo no era sindicalista

Cuando vinieron a por mí,ya no había nadie para protestar"
