Following are a number of back-translations as well as a sample translation for translators of Amos 4:11:

• Kupsabiny: “God is saying,
  ‘I destroyed some of you
  as I destroyed Sodom and Gomorrah.
  Those who remained among you were like
  a piece of wood that was burning but then snatched away.
  In spite of that,
  you did not return to me.” (Source: Kupsabiny Back Translation)
• Newari: “‘I destroyed many of you like
  I did destroy Sodom and Gomorrah.
  You were like burning coals pulled from the fire,
  yet you have not returned to me,’
  says the LORD” (Source: Newari Back Translation)
• Hiligaynon: “‘I destroyed some of you (plur.) like what I did to Sodom and Gomora. And some of you (plur.) who were-able-to-escape as-if like a wood which has-been-snatched-away from the fire. But you (plur.) still did- not -return to me. I, the Lord GOD, am-saying this.” (Source: Hiligaynon Back Translation)
