Following are a number of back-translations as well as a sample translation for translators of Jeremiah 11:20:

• Kupsabiny: “Then I prayed, ‘Oh, please, God of power, you are a true/just God. You know the thoughts of people. I have taken my cries to you over the plot of these people so that you can avenge them.’” (Source: Kupsabiny Back Translation)
• Hiligaynon: “But I prayed, O LORD Almighty, your (sing.) judgment is just, and you (sing.) know the mind and heart of a man. Show to me your (sing.) vengeance against them, for I handed-over to you (sing.) my case.’” (Source: Hiligaynon Back Translation)
• English: “Then I prayed, ‘Commander of the armies of angels, you judge people justly/fairly,
  and you examine everything that we are thinking.
  Allow me to watch you getting revenge on the people who want to kill me,
  because I trust that you will do for me what is right.’” (Source: Translation for Translators)
