First they came for the Socialists..

First they came for the Socialists, and I did not speak out— 
Because I was not a Socialist. 
Then they came for the Trade Unionists, and I did not speak out— 
Because I was not a Trade Unionist. 
Then they came for the Jews, and I did not speak out— Because I was not a Jew. 
Then they came for me—and there was no one left to speak for me.
