Following are a number of back-translations as well as a sample translation for translators of Isaiah 44:25:

• Kupsabiny: “I am angry with the sorcery of prophets,
  and I make witch doctors become confused.
  I overturn the words of those who think they are wise
  and make their wisdom become foolishness.” (Source: Kupsabiny Back Translation)
• Newari: “who destroys the prophecy of false prophets.
  who shows the words of the wise to be false
  and reveals the foolishness of their knowledge.” (Source: Newari Back Translation)
• Hiligaynon: “I have- caused-to-fail the prophecies of the false prophets. And I cause-to-become-fool the fortunetellers. I twist what the wise-ones say, and turn into nonsense what they knew.” (Source: Hiligaynon Back Translation)
