Following are a number of back-translations as well as a sample translation for translators of Jeremiah 2:7:

• Kupsabiny: “I brought (them) to rejoice in this fertile land,
  to eat its food/produce and all other good things.
  But they arrived suddenly to destroy my land.
  They defiled (it) to become a land that is detestable.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “I brought you (plur.) to the good land to benefit the good of its harvest. But when- you (plur.) -arrived there, you (plur.) defiled/[lit. made-filthy] the land that I possess, and you (plur.) made it detestable.” (Source: Hiligaynon Back Translation)
• English: “And when I brought you into a very fertile land,
  in order that you could enjoy all the fruit and other good things that you would harvest,
  you caused the land that I promised to give to you to be unfit for me
  and to become disgusting/detestable to me.” (Source: Translation for Translators)
