  barking like jackals.
  Their eyes are failing
  grass has gone.’” (Source: Kupsabiny Back Translation)
• Hiligaynon: “The wild donkeys stand on the clear/clean/bare hills and panting like a thirsty fierce animal/(wild dogs). Their eyesight becomes-dark because there is no vegetation/green-grass/pasture.’” (Source: Hiligaynon Back Translation)
• English: “The wild donkeys stand on the barren hills,
  panting like thirsty jackals/wolves.
  They become blind
  because there is no grass to eat.” (Source: Translation for Translators)
