Following are a number of back-translations as well as a sample translation for translators of Isaiah 30:17:

• Kupsabiny: “One enemy shall chase
  one thousand of your young men.
  You shall all flee from
  just five enemies.
  Few of your people shall remain/survive.
  It shall be like a tall tree alone on a hill,
  or a banner/flag that is alone on a mountaintop.” (Source: Kupsabiny Back Translation)
• Newari: “From the fear of one [soldier], one thousand [of you] will have to run away,
  [and] from the fear of five [soldiers] all of you will have to run away,
  except flag raised on a mountain peak
  a signal flag on top of a hill nothing will be left.” (Source: Newari Back Translation)
• Hiligaynon: “Just one of them can-drive-away a thousand of your (plur.) soldiers. And five of them can-drive-away all of you (plur.). You (plur.) will-be like a pole of a banner alone on the top of the mountain.’” (Source: Hiligaynon Back Translation)
• English: “As a result, 1,000 of you will flee when only one of them pursues you!
  When only five of their soldiers threaten to kill you,
  all of you will flee.
  Only a few of you will be left, like a single flagpole on top of a mountain
  with one signal flag on the pole.’” (Source: Translation for Translators)
