Following are a number of back-translations as well as a sample translation for translators of Isaiah 65:1:

• Kupsabiny: “God is saying,
  ‘I revealed myself to those who did not ask for me,
  those who were not searching for me found me.
  I said to those nations that did not call for me,
  ‘This is me, I am here.’” (Source: Kupsabiny Back Translation)
• Newari: “The LORD says, "who did not ask me I was ready to reply to them,
  I was yearning to meet my people
  but they were not even looking for me.
  Even though I said "I am here, I really am here,"
  my people did not pray to me.” (Source: Newari Back Translation)
• Hiligaynon: “The LORD said, ‘I have-made-known-myself to the people who did- not -ask about me. They saw me even if they did- not -look for me. I revealed myself even-though they did- not -call upon me.” (Source: Hiligaynon Back Translation)
• English: “This is what Yahweh said:
  ‘I was ready to reply to my people,
  but no one requested me to help them.
  I was ready to help even those who did not call out to me.
  I continued to say, ‘I am here to help you!’” (Source: Translation for Translators)
