  nor one that is dug out for making the foundation of a house
  because you have become a deserted place forever.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “No stone ever will-be-taken from you to be used to build a building. You will-become desolate without end. I, the LORD, (am) the-(one) saying this.’” (Source: Hiligaynon Back Translation)

  even the stones in your city will never again be used for buildings.
  Your city will be completely destroyed.’” (Source: Translation for Translators)
