Following are a number of back-translations as well as a sample translation for translators of Isaiah 49:7:

• Kupsabiny: “This is what the God of Israel is saying
  the one who is righteous and the savior
  He is saying to that land that is oppressed
  and much hated,
  ‘Kings shall see you and stand in awe/honoring.
  Leaders shall bow before you
  because I God is the one who stands on truth,
  I am the righteous one of Israel,
  who has chosen you.’” (Source: Kupsabiny Back Translation)
• Newari: “To the servant of the rulers whom the nations scorn very much,
  The LORD, redeemer and the holy God of Israel, says like this,
  "Kings will see you and they will come to stand before you.
  rulers will also see you and come to lie prostrate before you.
  For the LORD, the faithful one,
  the holy God of Israel has chosen you."” (Source: Newari Back Translation)
• Hiligaynon: “The LORD, the Savior and Holy God of Israel, said to the people which are-despised and detested/abhorred by the nations, and servant of the leaders/[lit. heads], ‘The kings will-see who really you (sing.) are and they will-stand to respect you (sing.). The leaders/[lit. heads] will-bow-down to honor you (sing.). This will-happen because of me, the LORD who is faithful, the Holy God of Israel. I am the one-who-have-chosen you (sing.).’” (Source: Hiligaynon Back Translation)
