First they came…

…They came first for the Communists,
And I didn’t speak up because I wasn’t a Communist;

And then they came for the trade unionists,
And I didn’t speak up because I wasn’t a trade unionist;

And then they came for the Jews,
And I didn’t speak up because I wasn’t a Jew;

And then… they came for me…
And by that time there was no one left to speak up.
