Following are a number of back-translations as well as a sample translation for translators of Jeremiah 48:18:

• Kupsabiny: “Come down also you people of Dibon
  from that place of honor where you are
  and sit down in the dust
  because the one destroying Moab has come/arrived to where you are,
  and has torn down the cities with a wall around.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “‘You residents of Dibon, [you (plur.)] be-humble and sit on the ground/sand, for the destroyer of Moab will- also -attack you (plur.) and they will-destroy your cities that (are)-surrounded-by-walls.” (Source: Hiligaynon Back Translation)
• English: “You people of Dibon city, stop being proud because of being honored,
  and sit in the dust/dirt,
  because those who will destroy other places in Moab will attack your city
  and destroy your high walls.” (Source: Translation for Translators)
