Following are a number of back-translations as well as a sample translation for translators of Isaiah 5:2:

• Kupsabiny: “He plowed that field and removed stones,
  he planted good vines.
  He built a place where one can watch from/look far
  and he prepared where one can squeeze its fruits.
  He thought that that farm would produce sweet fruit,
  but (he/it) produced bitter ones.” (Source: Kupsabiny Back Translation)
• Newari: “He prepared a field in the garden. He removed the stones and threw them away.
  He then planted the best grapevines there.
  [He] built a hut for watching the vineyard.
  Having carved a rock for squeezing grapes,
  [he] dug a pit. He hoped that it would yield good grapes,
  but it [only] yielded bad grapes.” (Source: Newari Back Translation)
• Hiligaynon: “He plowed it and cleared-it of stones, and planted-it with the finest vines.
  He built a place-of-watching/outpost in this field and dug a hole in a rock/stone for the-squeezing-out-place of grapes.
  He waited that it will-bear/yield sweet-(fruit), but it yielded sour-(fruit).” (Source: Hiligaynon Back Translation)
