Following are a number of back-translations as well as a sample translation for translators of Isaiah 28:1:

• Kupsabiny: “The city of Samaria is in a bad situation
  which the drunkards of Ephraim boast about.
  The beauty of that city is finished
  like flowers that are withered.
  That city is in a fertile valley
  and people whom beer rules are proud of it.” (Source: Kupsabiny Back Translation)
• Newari: “Woe to that proud crown of the drunken people of Ephraim!
  Alas, that crown, which is made by fading flowers,
  before it was very beautiful!
  It is a city up a fertile valley,
  belonging to those drunk with wine.” (Source: Newari Back Translation)
• Hiligaynon: “Woe to Samaria, who is like a crown-like flower, the pride of the drunkard leaders/[lit. heads] of Israel. This city is located in the fruitful plain/valley, but its beauty will-fade-away like a flower that withers.” (Source: Hiligaynon Back Translation)
