Following are a number of back-translations as well as a sample translation for translators of Jeremiah 8:14:

• Kupsabiny: “People ask themselves that,
  ‘Why are we sitting here quiet like this?
  Let us gather (and) flee to the cities
  that have been surrounded by a wall to go and perish there.
  God has abandoned us to be destroyed,
  he has given us poisoned water to drink,
  because we have wronged him.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “‘Then they will-say, ‘So, what we (incl.) are-waiting-for? Come let- us (incl.) -flee to the stone-walled towns, and let- us (incl.) -die there. For the LORD our (incl.) God has- already -sentenced us (incl.) to die. As-if just like he has-given us (incl.) water with poison so-that we (incl.) would drink, because we (incl.) have-sinned against him.” (Source: Hiligaynon Back Translation)
• English: “Then the people will say, ‘Why should we wait here in these small towns?/We should not wait here in these small towns. !
  We should go to the cities that have high walls around them,
  but even if we do that we will be killed there,
  because Yahweh our God has decided that we must be destroyed;
  it is as though he has given us a cup of poison to drink,
  because we sinned against him.” (Source: Translation for Translators)
