Following are a number of back-translations as well as a sample translation for translators of Isaiah 5:25:

• Kupsabiny: “So, God became angry with his people,
  and he shall throw(them) into calamity/disaster.
  The mountains will shake,
  and many people will die.
  Their bodies/corpses shall pile up
  in the cities like trash.
  But the anger of God does not subside,
  since (he) still wants to punish people.” (Source: Kupsabiny Back Translation)
• Newari: “So the LORD is angry with His people,
  and He has raised His hand to punish them.
  The mountains will tremble
  and corpses will even be discarded on the road like dust.
  But even after all that the anger of the LORD has not yet subsided,
  and His hand has been raised to punish them.” (Source: Newari Back Translation)
• Hiligaynon: “Therefore because of the severe wrath of the LORD against you (plur.) who are his people, he will-punish you (plur.). The mountains will-shake and your (plur.) corpse will-spread-out on the street like garbage. But the wrath of the LORD will- still not -cease. He is still ready to punish you (plur.).” (Source: Hiligaynon Back Translation)
