Following are a number of back-translations as well as a sample translation for translators of Isaiah 49:5:

• Kupsabiny: “But this is what God is saying to me now
  the one who created me while in the stomach to serve him.
  He anointed me to bring back the children of Jacob,
  for the people of Israel to come to where he is.
  I am honored by God
  and it he alone who gives me power/strength.” (Source: Kupsabiny Back Translation)
• Newari: “The one who made me to become his servant,
  to bring Jacob back to himself again,
  and to gather Israel back himself again.
  formed me in the womb before I was born,
  for I am one who has honor in the eyes of the LORD.
  and my God is the source of my strength,” (Source: Newari Back Translation)
• Hiligaynon: “The LORD is the one-who-made me to become his servant so-that I will-cause-to-return and gather the Israelinhon to him. The LORD honored me and he who is my God is the one (who) is-giving me strength.” (Source: Hiligaynon Back Translation)
