Following are a number of back-translations as well as a sample translation for translators of Isaiah 31:2:

• Kupsabiny: “But God is wise
  and is able to send them disaster.
  God does not turn himself back from the words/things that he wants to do.
  He shall punish the sinners
  and those who come to the sinners aid.” (Source: Kupsabiny Back Translation)
• Newari: “Yet, as for him, [he] has great wisdom
  and he is able to bring destruction, and he will not take back his word.
  He will rise against clans that do evil work and those who help those who do unrighteous work.” (Source: Newari Back Translation)
• Hiligaynon: “In the wisdom of the LORD he will-send destruction; he will- never -take-back what he has-said. He will-punish the household of the wicked people and the ones-(who)-help them.” (Source: Hiligaynon Back Translation)
