Following are a number of back-translations as well as a sample translation for translators of Jeremiah 9:22:

• Kupsabiny: “The corpses of people will be lying all around everywhere
  like manure that has been collected in the fields.
  like grains that the harvester has forgotten,
  and there is no one who will gather (them).
  The one speaking is I God.’” (Source: Kupsabiny Back Translation)
• Hiligaynon: “And the LORD said, ‘The corpses will-scatter like dung on the grazing-field, or like the heads-of-grain which were left by the harvesters, that no one gather them.’” (Source: Hiligaynon Back Translation)
• English: “There will be corpses scattered across the fields like dung;
  their dead bodies will lie there like grain that has been cut by reapers/farmers,
  and there will be no one still alive to bury them.” (Source: Translation for Translators)
