  and those who persecute you shall be like rubbish
  which the wind blows away.
  But/And suddenly,” (Source: Kupsabiny Back Translation)

  and as for their merciless forces,
  the wind will quickly blow [them] away like chaff.
  suddenly and unexpectedly” (Source: Newari Back Translation)

  their armies will disappear
  like chaff that is blown away by the wind.
  It will happen very suddenly.” (Source: Translation for Translators)
