Following are a number of back-translations as well as a sample translation for translators of Isaiah 53:4:

• Kupsabiny: “He endured our troubles
  and overcame for us our sicknesses.
  We thought that he might be punished,
  or maybe God struck (him) and made (him) suffer.” (Source: Kupsabiny Back Translation)
• Newari: “Actually, he carried our sicknesses,
  and [it was] our pains [that] he bore
  yet we thought that he was one whom God was punishing,
  and one who had fallen into suffering.” (Source: Newari Back Translation)
• Hiligaynon: “The truth is, he is the one-who-suffered the sorrows/[lit. hurts] and sufferings which would have been for us (incl.). We (incl.) thought that God had-punished him because of his sins.” (Source: Hiligaynon Back Translation)
