Following are a number of back-translations as well as a sample translation for translators of Isaiah 35:8:

• Kupsabiny: “A broad road/ path shall appear there
  and it shall be called ‘Road of righteousness’.
  Sinners shall not travel on that road
  but only the people of God shall walk on it.
  No fool shall get lost
  so that he crosses that road.” (Source: Kupsabiny Back Translation)
• Newari: “There will be a main road,
  [and] it will be called the road of holiness.
  No one who is unclean will go by way of it.
  But that road will only be for those who go from there by way of it.
  The wicked and fools will not get to go from there by way of it.” (Source: Newari Back Translation)
• Hiligaynon: “A broad/wide road will-be-put-up in those desert, and this road will-be-called ‘Holy Road.’ No sinner and foolish-one that can-pass-by there. Only those people who follow the ways of God (ones)-can-pass-by.” (Source: Hiligaynon Back Translation)
• English: “So I suggest that you make a deal with my master/boss, the king of Assyria. I will give you 2,000 horses, but I do not think that you can find 2,000 of your men who can ride on them!” (Source: Translation for Translators)
