Following are a number of back-translations as well as a sample translation for translators of Isaiah 52:7:

• Kupsabiny: “How good it is for (people) to see a person
  who is coming from the mountains.
  A person who has been sent to announce/speak out peace
  and bring good news.
  A person who shouts/promises salvation
  and says to Zion,
  ‘Your God is king!’” (Source: Kupsabiny Back Translation)
• Newari: “Going on the mountains,
  how beautiful are the feet of those who go to proclaim the good news,
  any who go to proclaim peace,
  who bring the good message and proclaim salvation,
  who speak to Zion like this — "Your God reigns."” (Source: Newari Back Translation)
• Hiligaynon: “How beautiful/nice if you (sing.) see the messengers who walk-through the mountains to bring the good news that there is now peace in Jerusalem and its situation will- now -be-good because God will-save it. They say to those of/from-Jerusalem, ‘Your (plur.) God reigns!’” (Source: Hiligaynon Back Translation)
