Following are a number of back-translations as well as a sample translation for translators of Isaiah 62:9:

• Kupsabiny: “But you shall eat your food that you harvested,
  and you shall give thanks to God.
  You shall drink your wine that you prepared in
  the compound of the house of God.’” (Source: Kupsabiny Back Translation)
• Newari: “But whoever reaps the harvest, they will get to eat it.
  And he will praise the LORD.
  Whoever gathers grapes
  later on they will drink it in the courtyard of my holy place."” (Source: Newari Back Translation)
• Hiligaynon: “You (plur.) who have-harvested the wheat are the ones-who-will-eat it, and you (plur.) will-praise me. You (plur.) who have-harvested the grapes are the ones-who-will-drink its juice there in my temple.’” (Source: Hiligaynon Back Translation)
