Following are a number of back-translations as well as a sample translation for translators of Amos 5:3:

• Kupsabiny: “The God of power says,
  ‘A city sends one thousand warriors to go into battle
  but only one hundred shall return.
  And if one sends one hundred warriors to war
  only ten will return.’” (Source: Kupsabiny Back Translation)
• Newari: “This is what the LORD God says –
  ‘A thousand soldiers from one city will go to war
  but just a hundred will survive.
  Fom another city a hundred soldiers
  will go for war yet only ten will be saved.’” (Source: Newari Back Translation)
• Hiligaynon: “Therefore the Lord GOD says, ‘Among 1,000 soldiers to be-sent by one city in Israel, only 100 will-be-left. And among 100 soldiers that she will-send, only 10 will-be-left.” (Source: Hiligaynon Back Translation)
• English: “This is what Yahweh the Lord says to the people of Israel:
  ‘When your enemies attack you,
  and when 1,000 of your soldiers will go to a battle,
  there will be only 100 who will survive.
  When 100 soldiers march out from a city to fight,
  there will be only ten who will remain alive.’” (Source: Translation for Translators)
