Following are a number of back-translations as well as a sample translation for translators of Isaiah 48:5:

• Kupsabiny: “So, I knew your words/matters long ago,
  I announced/promised (it) before it happened.
  I did not want a person to say that,
  it was his idol that made it come true
  or that that idol
  which he made caused those things to come true.” (Source: Kupsabiny Back Translation)
• Newari: “So I told you these matters long ago.
  I have told you these matters before they happened,
  so you could not say, ‘My gods have done these things.
  My idol made of wood and metal commanded it to happen –” (Source: Newari Back Translation)
• Hiligaynon: “That is why I already told you (plur.) before-hand what I will-do. Before this will-happen I already make- it -known to you (plur.) so that you (plur.) can- not -say that you (plur.) little-gods/false-gods which are made from wood and metal were- the -ones-who-prophesied and fulfilled it.” (Source: Hiligaynon Back Translation)
