Following are a number of back-translations as well as a sample translation for translators of Jeremiah 9:2:

• Kupsabiny: “I wish I had a place in the desert
  where I could stay
  so I could leave my people and go away
  leaving the place where they are,
  because (they) have been unfaithful/promiscuous,
  they are people who cannot be trusted.’” (Source: Kupsabiny Back Translation)
• Hiligaynon: “Wish I have a place-to-stay there in the desert/desolate-place so-that I can-go-away from my fellowmen, for all of them are deceitful to the LORD like a woman who commits-adultery-with-a-man.” (Source: Hiligaynon Back Translation)
