Following are a number of back-translations as well as a sample translation for translators of Isaiah 51:3:

• Kupsabiny: “God will make Zion happy,
  and he will make all its deserted homes joyful.
  He will make the desert become Eden,
  and change its dry land to become the garden of God.
  Joy shall be seen there
  and (people) shall sing and say thank you.” (Source: Kupsabiny Back Translation)
• Newari: “The LORD will certainly give consolation to Zion,
  and he will have mercy on their place that is full of desolation,
  And [he will make] the wilderness like garden of Eden
  and the dry ground there [he] will make like the garden of the LORD.
  There [the sounds of] joy and pleasure,
  the sounds of thanksgiving and song will be heard.” (Source: Newari Back Translation)
• Hiligaynon: “‘I will- surely -have-mercy-upon Jerusalem which has-been-ruined. Its deserts I will-make it like Eden my field/garden. Joy and gladness will-be-found-there in Jerusalem and there are also thanksgiving and singing.” (Source: Hiligaynon Back Translation)
