Following are a number of back-translations as well as a sample translation for translators of Isaiah 31:4:

• Kupsabiny: “The God of power told me that
  he would come down to fight
  and defend the mountain of Zion.
  He will be like a lion that roars
  while eating a goat he has caught.
  Even if the shepherds shout very loudly
  that lion is not afraid.” (Source: Kupsabiny Back Translation)
• Newari: “The LORD says like this,
  "Just as a lion or a big lion growls [over] its prey,
  and a whole group of shepherds rises up against it,
  [and] yet it is neither afraid of their voices,
  nor of their shouting, and [it] moves hither and thither.
  Just like that the LORD Almighty will come down to fight on Mount Zion and its hill.” (Source: Newari Back Translation)
• Hiligaynon: “This is what the LORD has-said to me, ‘No one can-stop/hinder a lion to devour its victim even if the ones-who-watches animals will-shout. Like me also, no one can- stop/hinder me to protect Jerusalem.” (Source: Hiligaynon Back Translation)
• English: “But this is what Yahweh said to me:
  ‘When a huge lion stands over the body of a sheep that he has killed and growls,
  even if a large group of shepherds comes to chase/shoo away the lion,
  even if they shout loudly,
  the lion will not be afraid and will not leave.
  Similarly, I, the Commander of the armies of angels, will come down
  to fight my enemies on Zion Hill,
  and nothing will hinder me.” (Source: Translation for Translators)
