Following are a number of back-translations as well as a sample translation for translators of Isaiah 62:5:

• Kupsabiny: “God shall build you and guard you
  like when a husband guards his bride.
  God shall rejoice over you
  like a man rejoices over the bride he is marrying.” (Source: Kupsabiny Back Translation)
• Newari: “Just as a young man will marry a woman who is not yet married,
  so your people will take possession of you.
  a man who will be getting married will rejoice for his bride,
  just like that your God will also rejoice for you.” (Source: Newari Back Translation)
• Hiligaynon: “He who created you will-marry you (sing.) like a young man who married a virgin. And same-as a groom is happy/pleased with his bride, your (sing.) God will- also -be-happy/pleased with you (sing.).” (Source: Hiligaynon Back Translation)
