Following are a number of back-translations as well as a sample translation for translators of Jeremiah 15:14:

• Kupsabiny: “I shall make you go and become slaves of your enemies
  in a land you do now know
  because my anger has risen up
  like a fire which cannot be extinguished.’” (Source: Kupsabiny Back Translation)
• Hiligaynon: “I will-cause you (plur.) -to-be-enslaved by your (plur.) enemies in the place that you (plur.) do- not -know, and I will-cause -you (plur.) -to-experience my anger which is like a blazing fire.’” (Source: Hiligaynon Back Translation)
• English: “I will tell your enemies to force you to become their prisoners,
  and to take you to other lands that you do not even know about,
  and force you to become their slaves.
  That will happen because I am extremely angry with you;
  my being angry is like a fire that will burn forever.’” (Source: Translation for Translators)
