Following are a number of back-translations as well as a sample translation for translators of Jeremiah 9:11:

• Kupsabiny: “Then God said,
  ‘I shall destroy Jerusalem to become a ruin
  to become caves where jackals are screaming,
  and the cities of Judah,
  I shall make those to become a wilderness.’” (Source: Kupsabiny Back Translation)
• Hiligaynon: “For the LORD said, ‘I will-destroy Jerusalem, and this will- now -become just a place-of-dwelling of the wild dogs. I will-make the towns of Juda into desolate and no one will-live there.’” (Source: Hiligaynon Back Translation)
• English: “Yahweh also says, ‘I will cause Jerusalem to become a heap of ruins,
  and only jackals/wolves will live there.
  I will destroy the towns of Judah, with the result that they will be completely deserted;
  no one will live there.’” (Source: Translation for Translators)
