Following are a number of back-translations as well as a sample translation for translators of Isaiah 60:2:

• Kupsabiny: “Darkness closes the world/land
  and it envelopes the communities.
  Darkness that has closed covers the nations.
  But God will shine on you
  so his light is seen where you are.” (Source: Kupsabiny Back Translation)
• Newari: “Look! Darkness [has covered] the earth
  and intense darkness has covered the people,
  but the light of the LORD has come to you,
  and the glory of the LORD has come to appear to you.” (Source: Newari Back Translation)
• Hiligaynon: “The nations in the world will-be-covered by too much darkness, but you (sing.) on-the-other-hand will-be-shined by the powerful presence of the LORD.” (Source: Hiligaynon Back Translation)
