Following are a number of back-translations as well as a sample translation for translators of Isaiah 18:2:

• Kupsabiny: “People who have been sent from that country are coming.
  The have followed the river Nile.
  They come in boats that are made from reeds.
  Return quickly you people.
  Go to the land of people who are tall
  and smooth in their appearance.
  That community is fierce and feared in the whole world
  and rivers are dividing their land.” (Source: Kupsabiny Back Translation)
• Newari: “From that land ambassadors have been coming,
  going by way of the Nile River with boats made of bamboo reeds.
  O [you] ambassadors who are able to run fast, go quickly!
  To a Nation which people tall and smooth skin,
  The people feared near and far from them,
  They were very strong and victorious
  Their language is strange, their country is divided by river” (Source: Newari Back Translation)
• Hiligaynon: “From this place, there are messengers who are-being-sent riding in a something-one-rides-on which is made from reed, and passed-through the Nile River.
  You (plur.) who are swift messengers, you (plur.) return now to your (plur.) land which are divided by the rivers. You (plur.) return to your (plur.) peoples who are tall and fine skin, peoples who are powerful and being-feared everywhere.” (Source: Hiligaynon Back Translation)
