Following are a number of back-translations as well as a sample translation for translators of Isaiah 5:28:

• Kupsabiny: “Their arrows are sharp
  and their bows are tied/strung.
  Their fierce horses run quickly,
  and their chariots stir up the dust.” (Source: Kupsabiny Back Translation)
• Newari: “Their arrows are very pointed and,
  having been put on the bow, are ready to shoot.
  The hoofs of their horses are as hard as flint stone,
  and the wheels of [their] chariots spin like the whirlwind.” (Source: Newari Back Translation)
• Hiligaynon: “Their arrows are pointed and their bows-and-arrows are prepared. Their horses’ hoof is like a very hard rock, and the spining of the wheel of their chariots is like a whirlwind.” (Source: Hiligaynon Back Translation)
