Following are a number of back-translations as well as a sample translation for translators of Jeremiah 51:56:

• Kupsabiny: “The destroyer is headed towards Babylon,
  its soldiers will be captured,
  their bows will be broken to pieces.
  It is I God who am punishing people,
  truly, I avenge to the full because they deserve it.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “The destroyer of Babilonia will-arrive and her soldiers will-be-taken-captive, and their bows will-be-broken. For I, the LORD, is the God who punishes a wicked-one. And I will-punish Babilonia what she deserves.” (Source: Hiligaynon Back Translation)
