  He opens for him closed doors

  The one who I have given power to,
  to defeat nations,
  to seize power from the hands of the kings,
  to open the main gates of the cities
  and the gates are not able to stay closed against him,
  I, the LORD to Cyrus say like this — ” (Source: Newari Back Translation)
