Following are a number of back-translations as well as a sample translation for translators of Jeremiah 15:13:

• Kupsabiny: “God is saying to people,
  ‘I shall give out your (plur.) riches/wealth and the things you have heaped up
  for the enemies to take for themselves in an easy way.
  I am doing like that because of all your sins
  that you have been going around doing in the whole land.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “Your (plur.) wealth and properties I will-cause-to-be-plundered by the enemies because of all your (plur.) sins that you (plur.) have-done in the whole nation.” (Source: Hiligaynon Back Translation)
• English: “I will give all the valuable possessions of the people of Judah to their enemies,
  without them paying for it.
  Their valuable possessions will be the payment/reward that I will give them
  because of all the sins that you have committed throughout your country.” (Source: Translation for Translators)
