Following are a number of back-translations as well as a sample translation for translators of Isaiah 58:2:

• Kupsabiny: “You worship me each day
  and you rejoice over my ways.
  But you pretend to keep/follow righteousness
  and not forgetting my will.
  You want that I make just decisions
  and you are happy to bow before me.” (Source: Kupsabiny Back Translation)
• Newari: “Because they search me daily.
  and they seem like they want to know my ways,
  They seem like those who act what is right
  and obey my commands.
  They ask me for the right decision
  And They desire God come before them.” (Source: Newari Back Translation)
• Hiligaynon: “The take-refuge on me every day, and as-if they really wanted to know my ways. When looking-at (them) as-if they are a righteous nation and do not reject my commands. They show that as-if they really wanted to come-near to me and ask for a right judgment.” (Source: Hiligaynon Back Translation)
• English: “They worship me every day;
  they come to my temple because they say that they are eager to know what I want them to do.
  They act as though they are a nation that does things that are righteous,
  who would never abandon their God.
  They request me to decide matters justly,
  and they delight to come to worship me.” (Source: Translation for Translators)
