Following are a number of back-translations as well as a sample translation for translators of Isaiah 42:22:

• Kupsabiny: “But this a people who has been robbed
  and (its) things plundered.
  They are all closed inside holes
  and they stay tied up (in prison).
  They have become (people) whom are robbed of (their) things and no one rescues (them).
  Their things were plundered and no one is saying, ‘Return (them).’” (Source: Kupsabiny Back Translation)
• Newari: “But this is one nation [of people] like that,
  who have been plundered.
  Having been made prisoners, [they] have been imprisoned in dungeons.
  They have been made plunder,
  and no one will come to release them and take them back home.” (Source: Newari Back Translation)
• Hiligaynon: “But now his people were-robbed, plundered of properties, put-to-prison into the pit or prison-cell, and no one helped them.” (Source: Hiligaynon Back Translation)
