Following are a number of back-translations as well as a sample translation for translators of Isaiah 53:11:

• Kupsabiny: “He shall rejoice when that suffering is over.
  It is fitting/right that he did not suffer for nothing.
  The servant of God who is righteous shall make
  many people become righteous.
  He shall carry their sins.” (Source: Kupsabiny Back Translation)
• Newari: “After he has eaten great trouble with his soul,
  he will experience the light of life and will be satisfied.
  Because of his knowledge my righteous servant will enable many to be made righteous.
  He will bear their unrighteousness.” (Source: Newari Back Translation)
• Hiligaynon: “When he will-see the fruit/[lit. had-done] of his sufferings, he will-be-happy. The LORD said, ‘By the wisdom of my righteous servant he will-make- many -righteous; he will-suffer for their sins.” (Source: Hiligaynon Back Translation)
