Following are a number of back-translations as well as a sample translation for translators of Jeremiah 12:12:

• Kupsabiny: “People have thronged in all the ridges in the desert
  wanting to come and plunder things from here.
  I have sent war to burn up the whole land
  so that not even one person has peace.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “The destroyers will-arrive on the clear mountains in the desert to destroy the entire land, and no one can-flee.” (Source: Hiligaynon Back Translation)
• English: “The soldiers of our enemies have marched across all the barren hilltops.
  But I, Yahweh, am using those armies to punish your land from one end to the other,
  and no one will escape.” (Source: Translation for Translators)
