First they came.

 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.
