  and make what my people say come true.
  I am saying that Jerusalem again shall be lived in
  and the cities of Judah shall be rebuilt
  those that had become ruins.” (Source: Kupsabiny Back Translation)
• Newari: “who carries out the word of his prophet.
  and fulfills the words of his messengers who say what will happen,
  who says about Jerusalem, ‘people will live in this city again.’
  who says about towns of Judah, ‘they will be built again’
  who says about that which has been destroyed, ‘They will be built again.’” (Source: Newari Back Translation)
• Hiligaynon: “I fulfill the prophecies of my servant and messengers. I say that Jerusalem will-be-inhabited again, and the other cities of Juda which have-been-destroyed will-be-built again.” (Source: Hiligaynon Back Translation)
