Following are a number of back-translations as well as a sample translation for translators of Isaiah 48:14:

• Kupsabiny: “You all gather together and listen.
  Which among those things that are worshipped
  is there who have said these words/matters.
  I God have chosen a person who is coming.
  He shall do the things that I want in Babylon
  and his soldiers shall fight the Chaldeans.” (Source: Kupsabiny Back Translation)
• Newari: “Gather in one place all of you [and] listen!
  Who among the gods has previously told [of] this matter?
  The one chosen by the LORD will fulfill his desire against Babylon,
  and he will raise his strong hand against the Babylonians. ” (Source: Newari Back Translation)
• Hiligaynon: “‘[You (plur.)] all gather-together and listen: Which of the little-gods/false-gods who prophesied to attack Babilonia by my friend to fulfill my plan against this nation? None [intensifier]!” (Source: Hiligaynon Back Translation)
