Following are a number of back-translations as well as a sample translation for translators of Isaiah 54:17:

• Kupsabiny: “The weapons shall not harm you (sing.)
  those that (people) want to kill you with.
  You (sing.) shall defeat (by arguments)
  anyone who accuses you in front of elders of the court.
  These are the matters that I shall do for my servants.
  I shall save them.
  It is me God who has spoken.’” (Source: Kupsabiny Back Translation)
• Newari: “But no such weapons made in any way to destroy you will be able to defeat you.
  And to those who accuse you, you will silence,
  this will be inheritance for the servants of the LORD.
  the reward that I will give them,’
  The LORD Almighty has declared [this].” (Source: Newari Back Translation)
• Hiligaynon: “There is no weapon that was-made that will-win-over you (sing.), and you (sing.) can answer the accusations against you (sing.). This is what my servants can possess. The will receive victory with righteousness from me. I, the LORD, (am) the-(one) saying this.’” (Source: Hiligaynon Back Translation)
