  until he has rebuilt Jerusalem,
  to become a city that the whole world honors.” (Source: Kupsabiny Back Translation)

  [as long as] its glory is not yet exalted over all the earth,
  until that time do not allow him to take any rest.” (Source: Newari Back Translation)
• Hiligaynon: “[You (plur.)] do- not -let- the LORD -rest/stop [meaning keep asking him] until he will-build-up Jerusalem again and he will-make it a praiseworthy place in the world.” (Source: Hiligaynon Back Translation)
