Following are a number of back-translations as well as a sample translation for translators of Isaiah 28:4:

• Kupsabiny: “The beauty of that city is finished
  which is in a fertile valley.
  It shall be like a fig tree
  that has ripened early.
  When a person sees that fruit, (he/they) pluck (it)
  and eat (it) right away.” (Source: Kupsabiny Back Translation)
• Newari: “That crown which is made by fading flowers,
  before it was very beautiful!
  It is a city up a fertile valley,
  and will be like the first figs of the spring season
  which will be eaten by people
  as soon as they see them.” (Source: Newari Back Translation)
• Hiligaynon: “This city is located in the fruitful plains/valley, but its beauty will-fade-away like a flower that withers. It will-be-destroyed right-away like the first fruits of fig which is-taken and eaten immediately by each-one who sees (it).” (Source: Hiligaynon Back Translation)
