Following are a number of back-translations as well as a sample translation for translators of Isaiah 51:20:

• Kupsabiny: “Your children fainted,
  and they lay there at the street corners.
  They were like an antelope caught in a trap.
  They received the pain/punishment that God sent them
  and they suffered the consequences because of God’s anger.” (Source: Kupsabiny Back Translation)
• Newari: “Your sons have been fainting.
  Like a deer entangled in a trap, having no strength, they have fallen down on the road.
  They have the anger of the LORD and
  you are full of God’s warning.” (Source: Newari Back Translation)
• Hiligaynon: “They all fainted and are-lying-down in the small-alley-way of each road. They are like deer trapped in a net. They experienced the severe wrath of the LORD; your (sing.) God rebuked them.” (Source: Hiligaynon Back Translation)
