Following are a number of back-translations as well as a sample translation for translators of Isaiah 14:23:

• Kupsabiny: “I shall turn Babylon to become a country that is a muddy place
  and animals shall live there.
  I shall sweep that land with disaster/death,
  like when a broom sweeps a house.’” (Source: Kupsabiny Back Translation)
• Newari: “and I will make Babylon a place where owls live
  and swampland.
  Sweeping the earth with a broom, I will destroy all their things."
  The LORD Almighty has spoken.” (Source: Newari Back Translation)
• Hiligaynon: “I will-make this into a desolate-place, which has many swamplands. I will-destroy it seems-like I will-sweep- (it) -with-the-broom. I, the LORD Almighty, (am) the-(one) saying this.’” (Source: Hiligaynon Back Translation)
• English: “I will cause Babylon to be a place where owls live,
  a place full of swamps;
  I will get rid of it completely
  as though I were sweeping it with a broom.
  That is what I, the Commander of the armies of angels, say.’” (Source: Translation for Translators)
