Following are a number of back-translations as well as a sample translation for translators of Isaiah 60:19:

• Kupsabiny: “You shall no longer rely on the light of the sun during the day,
  or that of the moon at night.
  God shall give you light which does not end
  and he shall become your greatness/glory.” (Source: Kupsabiny Back Translation)
• Newari: “The sun will never give you light during the day,
  nor will the moon be caused to shine brightly, giving you light,
  for the LORD will always be light for you.
  as for your God, he will be your glory.” (Source: Newari Back Translation)
• Hiligaynon: “‘The sun and the moon no longer will-be-light to you (sing.) on the day-time and night-time, for I, the LORD, is now your (sing.) light without end. I your (sing.) God is now your (sing.) beauty.” (Source: Hiligaynon Back Translation)
