Following are a number of back-translations as well as a sample translation for translators of Jeremiah 12:9:

• Kupsabiny: “My people whom I have chosen are like
  a bird that eagles have surrounded.
  Let also the animals of the bush come
  let them all come together and gather to eat (them).” (Source: Kupsabiny Back Translation)
• Hiligaynon: “They became detestable to me like a swooping bird. And they themselves were-surrounded by the swooping birds. I will-cause-to-gather all the fierce animals to eat- them -up.” (Source: Hiligaynon Back Translation)
• English: “My chosen people have become like speckled hawks
  that are surrounded by vultures waiting to eat their flesh after they are dead.
  Tell all the wild animals to come
  and eat the flesh of their corpses.” (Source: Translation for Translators)
