Following are a number of back-translations as well as a sample translation for translators of Isaiah 62:8:

• Kupsabiny: “God has promised something in his power.
  He said,
  ‘Never again will I give your food to the enemies
  and foreigners shall not drink your wine that you struggled for.” (Source: Kupsabiny Back Translation)
• Newari: “The LORD has sworn by his right hand
  and has sworn by his all-powerful [lit.: strongest of all] arm,
  "Never again will I give your grain to your enemies to eat.
  and your new wine for which you have worked,
  foreigners will never get to eat it.” (Source: Newari Back Translation)
• Hiligaynon: “The LORD has-sworn that he will-do this thing by-means of his power: ‘I will- never again -allow/cause- your (plur.) grains -be-eaten by your (plur.) enemies those of/from-other places. They will- no-longer -drink your (plur.) wine which you (plur.) have-toiled.” (Source: Hiligaynon Back Translation)
