Following are a number of back-translations as well as a sample translation for translators of Isaiah 14:20:

  because you despised your land and killed your people.
  Never shall your children be seen at all,
  because you became a sinner!” (Source: Kupsabiny Back Translation)
• Newari: “At the time to bury corpses, you will not be united with them,
  for you have destroyed your own country,
  and you have also destroyed your own people.
  None of the descendants of the wicked will ever take a name.” (Source: Newari Back Translation)
• Hiligaynon: “You (sing.) will- not -be-buried like the other kings, for you (sing.) destroyed your (sing.) nation and killed your (sing.) people. No one will-be-left alive of your (sing.) wicked family.” (Source: Hiligaynon Back Translation)
• English: “Your corpse will not be buried
  because you have destroyed your nation
  and have caused your people to be killed.
  The descendants of wicked people like you will never be honored again.” (Source: Translation for Translators)
