Following are a number of back-translations as well as a sample translation for translators of Jeremiah 18:21:

• Kupsabiny: “So, oh God, send famine to their children
  and (they) be speared with a sword to die in battle.
  Let the children die from their wives
  and they become widows.
  Let sicknesses kill the elders/old men
  and the young men be speared in battle.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “But now, let their children die in famine and in war. Let their females become-widow and lose their children. Let their males die of disease and their young-(men) in war.” (Source: Hiligaynon Back Translation)
• English: “So now, allow their children to die from hunger!
  Or cause them to be killed by their enemies’ swords!
  Cause their wives to become widows, whose children are all dead!
  Cause their old men to die in a plague,
  and cause their young men to be killed in battles!” (Source: Translation for Translators)
