Following are a number of back-translations as well as a sample translation for translators of Jeremiah 18:16:

  bringing them shame forever.
  Everyone who passes by there shall be surprised
  and shake his head in wonder.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “Their land will-become desolate and object-of-scorn forever/[lit. until whenever]. All who will-pass-by will- surely -be-astonished/stunned/[lit. not-able-to-speak] and will-shake-(their-)head.” (Source: Hiligaynon Back Translation)
• English: “Therefore, their land will become desolate,
  and people who see it will hiss to ridicule it.
  Everyone who passes by will be appalled;
  they will shake their heads to show that they are shocked.” (Source: Translation for Translators)
