Following are a number of back-translations as well as a sample translation for translators of Isaiah 28:13:

• Kupsabiny: “Those people take the words of God
  like just noise.
  So, those people shall be punished
  and then captured and sent away.” (Source: Kupsabiny Back Translation)
• Newari: “So the word of the LORD for them will be like this:
  For, teaching like this, here a little, there a little,
  then telling [it] again and again,
  then saying [it] again and again.
  so they will stumble and fall,
  they will be injured, trapped and captured.” (Source: Newari Back Translation)
• Hiligaynon: “Therefore the LORD will-teach them letter for letter, line for line, lesson for lesson. And they will-fall-down when they walk, be-wounded, trapped, and captured.” (Source: Hiligaynon Back Translation)
