Following are a number of back-translations as well as a sample translation for translators of Isaiah 59:3:

• Kupsabiny: “Your hands are unclean
  because you have shed blood
  and your fingers are not clean

  You have lied
  and you speaking evil/sinful words.” (Source: Kupsabiny Back Translation)
• Newari: “For your hands are covered with blood
  and your fingers are stained with guilt,
  and your mouth speaks lies [lit.: matters that are not true],
  and your tongue speaks evil [lit.: matters that are not good].” (Source: Newari Back Translation)
• Hiligaynon: “For you (plur.) kill people, and do other wickedness. You (plur.) lie and speak evil.” (Source: Hiligaynon Back Translation)
