Following are a number of back-translations as well as a sample translation for translators of Jeremiah 8:19:

• Kupsabiny: “Listen to the cries of my people,
  they come from all over the country.
  Those people are crying,
  ‘Is God not in Zion?
  Is its king no longer there?’ ’
  God said,
  ‘But these people made me angry
  over the idols that they are worshipping
  those of other countries, (didn’t they)?’” (Source: Kupsabiny Back Translation)
• Hiligaynon: “Listen to the weeping of my fellowmen; this can-be-heard in the whole land. They say, ‘Is the LORD no longer in Jerusalem? Is God the King of Jerusalem is no longer there?’ The LORD replied, ‘Why did- you (plur.) -provoke- me -to-anger by worshiping worthless little-gods?’” (Source: Hiligaynon Back Translation)
