Following are a number of back-translations as well as a sample translation for translators of Isaiah 30:27:

• Kupsabiny: “Please, God is coming from a faraway country,
  very angry and emitting something like smoke.
  He speaks fiercely
  and his words scorch people like fire.” (Source: Kupsabiny Back Translation)
• Newari: “Look! With burning anger and columns of bellowing [lit.: thickly coming] smoke,
  "The LORD Himself is coming from far away to show his great name.
  His lips are full of anger
  and his tongue is like a devouring fire. [lit.: a fire that reduces [things] to ashes.]” (Source: Newari Back Translation)
• Hiligaynon: “Listen! The LORD is-coming from afar whose anger is burning and he is-covered with smoke. His words with anger are like a blazing fire.” (Source: Hiligaynon Back Translation)
• English: “It is as though we see Yahweh coming from far away;
  he is extremely angry,
  and there are thick clouds of smoke around him.
  By what he says he shows that he is angry;
  what he says is like a devastating/destructive fire.” (Source: Translation for Translators)
