Well the original poem goes

First they came for the Communists And I did not speak out Because I was not a Communist Then 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 out for me

I changed it a little when writing for dramatic purposes as well as not remembering verbatim
