Following are a number of back-translations as well as a sample translation for translators of Isaiah 25:5:

• Kupsabiny: “and it is like a hot desert.
  But you have extinguished the words/matters of those ruthless people,
  like when a cloud cools a hot day.” (Source: Kupsabiny Back Translation)
• Newari: “and like hot sunlight coming to attack in the wilderness.
  But LORD, you shut the mouths of your enemy,
  and like a cloud cools the heat
  you stop the voices of merciless people.” (Source: Newari Back Translation)
• Hiligaynon: “and like the heat in the desert. But you (sing.) silence the shouting of those who-came-from-other nations. You (sing.) stopped the singings of the cruel people, like the heat which has-disappeared because the cloud covered (it).” (Source: Hiligaynon Back Translation)
