Following are a number of back-translations as well as a sample translation for translators of Job 9:15:

• Kupsabiny: “Even if I was without mistake, I could not answer him a word,
  but I pray/beg that God will have mercy on me when he makes a verdict.” (Source: Kupsabiny Back Translation)
• Newari: “Even though I have no guilt, I will not be able to answer [him].
  With the one who judges me guilty I will only be able to plead for mercy.” (Source: Newari Back Translation)
• Hiligaynon: “Even if I am innocent, I can- not -defend myself. The only I can do is to plead-for-mercy to God my Judge.” (Source: Hiligaynon Back Translation)

  All I could do would be to request God, my judge/accuser, to act mercifully toward me.” (Source: Translation for Translators)
