For some reason this poetic description of the GPU, or Cheka, reminds me of Genesis 3:24:
From that time on, the GPU has been the terror of the bourgeoisie, the vigilant guardian of the revolution, the naked sword of the proletariat (Stalin. Works, vol. 10, p. 240).
In Genesis we have the angelic bouncer, with ‘a sword flaming and turning to guard the way’. Like the Cheka, both protective and fearsome, striking hope and fear into the same heart.
