Following are a number of back-translations as well as a sample translation for translators of Lamentations 4:19:

• Kupsabiny: “Those people run so swiftly
  more than when an eagle rushes forth.
  They chased us on the mountains
  and laid an ambush in the wilderness.” (Source: Kupsabiny Back Translation)
• Newari: “Those who chased us ran faster
  than eagles flying in the sky.
  They pursued us to the mountains,
  they hid in the wilderness to attack us.” (Source: Newari Back Translation)
• Hiligaynon: “Our enemies who pursue us were swifter than the eagles. They pursue us up to the mountains. And even if we are in the desolate-place they are there also waiting to attack us.” (Source: Hiligaynon Back Translation)
• English: “Those who pursued us were faster than eagles flying in the sky.
  Even if we fled to the mountains
  or hid in the desert,
  they went there ahead of us and waited to attack us.” (Source: Translation for Translators)
