Following are a number of back-translations as well as a sample translation for translators of Joel 2:10:

• Kupsabiny: “The ground shakes on account of them
  and the sky/up is shaking.
  The sun and moon lose their light
  and the stars do not shine.” (Source: Kupsabiny Back Translation)
• Newari: “Before them, the earthquakes
  and the sky trembles.
  The sun and the moon will be darkened
  and stars will no longer shine.” (Source: Newari Back Translation)
• Hiligaynon: “The earth and the heavens shake upon their arrival. And the sun and the moon grow-dark and the stars no-longer shine.” (Source: Hiligaynon Back Translation)
