Following are a number of back-translations as well as a sample translation for translators of Isaiah 16:8:

• Kupsabiny: “The fields of Heshbon are spoiled,
  and there are no grapes/vines in Sibmah.
  Those grapes/vines were amazing,
  and they made the kings of the areas become drunk.
  Those grapes were brought up to the city of Jazer
  and were spread to the desert in the East.
  Those grapes went
  up to reaching the other side of the Lake of Salt.” (Source: Kupsabiny Back Translation)
• Newari: “The fields of Heshbon and the grapevines of Sibmah have also dried up.
  The rulers of the nations have trampled all their beautiful grape vines with their feet.
  Some time ago the grapevines of that place had extended up to Jazer,
  and had gone spreading as far as the wilderness.
  Its buds, having spread,
  passed over to the other side of the dead sea.” (Source: Newari Back Translation)
• Hiligaynon: “The fields/farms in Heshbon were-destroyed and as-well-as the fields of grape/(vineyards) in Sibma. The leaders/[lit. heads] of the nations destroyed these fields of grape/(vineyards) which reached-up Jazer, going to the desert, and still reached-up to the Red Sea.” (Source: Hiligaynon Back Translation)
• English: “The crops in the fields at Heshbon city will wither,
  and the vineyards at Sibmah town will wither also.
  The armies of other nations will destroy Moab,
  which is like a beautiful grapevine
  whose branches spread north to Jazer town
  and east to the desert.
  Its branches spread very far west,
  to the west side of the Dead Sea.” (Source: Translation for Translators)
