Following are a number of back-translations as well as a sample translation for translators of Isaiah 50:7:

• Kupsabiny: “God helps me,
  so I am thinking nothing (about it).
  I am seeing without fear
  and I know that I shall not be disgraced/shamed.” (Source: Kupsabiny Back Translation)
• Newari: “I will not fall into shame,
  for the LORD God helps me.
  I have determined to be as hard as flint,
  and I know that I will not fall into shame.” (Source: Newari Back Translation)
• Hiligaynon: “But I did not feel shame, for the Lord GOD helps me. Therefore I just remained-hard like a flint stone, for I know that I will- not -be-put-to-shame.” (Source: Hiligaynon Back Translation)
• English: “But, because the Lord our God helps me,
  I will never be humiliated.
  Therefore, I am strongly determined to face/endure difficulties,
  and I know that nothing will cause me to be ashamed.” (Source: Translation for Translators)
