Following are a number of back-translations as well as a sample translation for translators of Isaiah 1:23:

• Kupsabiny: “You leaders disobeyed,
  and they joined with thieves.
  All love bribes,
  and useless things.
  (They) do not even rescue poor children,
  and have no mercy for widows.” (Source: Kupsabiny Back Translation)
• Newari: “Your leaders have became rebels and friends of thieves.
  They always want to get [Lit.: eat] gifts and bribes.
  They would not defend orphans in court. [Lit. When verdicts are rendered, they do not take sides with those who have no mother or father.]
  They would not represent widows in court. [Court cases of those who have no husbands do not come to them.]” (Source: Newari Back Translation)
• Hiligaynon: “Your (sing.) leaders/[lit. heads] are rebels and companions of thieves. They always want a bribe, and they ask-for gifts. They do- not -defend the rights of the parentless/orphans and they do- not -listen to the complaints of the widows.” (Source: Hiligaynon Back Translation)
