Following are a number of back-translations as well as a sample translation for translators of Isaiah 41:24:

• Kupsabiny: “Those idols are truly useless
  and they cannot do anything.
  One should keep away from anybody
  who bows to those things.” (Source: Kupsabiny Back Translation)
• Newari: “But you are useless,
  and your work is totally useless. [lit. not even one little bit of your work is useful]
  The ones who have chosen you are repulsive.” (Source: Newari Back Translation)
• Hiligaynon: “But the truth is, you (plur.) are no value/nothing, and you (plur.) have done nothing at-all. The ones who-choose to worship you (plur.) are-detestable.” (Source: Hiligaynon Back Translation)
