Als die Nazis die Kommunisten holten,
habe ich geschwiegen;
ich war ja kein Kommunist.

Als sie die Sozialdemokraten einsperrten,
habe ich geschwiegen;
ich war ja kein Sozialdemokrat.

Als sie die Gewerkschafter holten,
habe ich nicht protestiert;
ich war ja kein Gewerkschafter.

Als sie die Juden holten,
habe ich geschwiegen;
ich war ja kein Jude.

Als sie mich holten,
gab es keinen mehr, der protestieren konnte.
