Following are a number of back-translations as well as a sample translation for translators of Isaiah 59:1:

• Kupsabiny: “Please/listen, do not think (plur.) that God is so weak
  that he is unable to save you (plur.).
  And do not think that he might be so deaf
  that he does not hear when you call (him).” (Source: Kupsabiny Back Translation)
• Newari: “Surely the hand of the LORD has not become short so that it is not able to deliver,
  and his ear has also not become dense so that it is not able to hear.” (Source: Newari Back Translation)
• Hiligaynon: “Listen! The LORD is not weak that he could not save you (plur.), or he is not deaf that he could not hear if you (plur.) call on him.” (Source: Hiligaynon Back Translation)
