Following are a number of back-translations as well as a sample translation for translators of Jeremiah 49:18:

• Kupsabiny: “Events will happen in Edom
  that are like what happened with Sodom and Gomorrah
  when (they) were destroyed with all their neighboring villages.
  Never shall a person live in that place again
  and it shall be desolate forever.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “Just as Sodom and Gomora were-destroyed and its surrounding towns, Edom will- also -be-destroyed. And no one ever live there. I, the LORD, (am) the-(one) saying this.” (Source: Hiligaynon Back Translation)
• English: “Edom will be destroyed as completely as Sodom and Gomorrah and the nearby towns were destroyed long ago.
  As a result, no one will live there any more.” (Source: Translation for Translators)
