Following are a number of back-translations as well as a sample translation for translators of Ezekiel 21:12:

  scream and shout!
  This sword is directed to my people of Israel
  and all their leaders.
  All leaders will be killed
  together with my people.
  Hold the cheeks only.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “‘Man, cry-out loudly and pound/beat your chest in sadness for that sword will-kill my people who are Israelinhon and their leaders.” (Source: Hiligaynon Back Translation)
• English: “So, you human, cry and wail,
  because I will use my sword to kill my people,
  including the leaders of Israel.
  They and all the other people, my people,
  will be killed by swords,
  so beat your chestto show that you are sad.” (Source: Translation for Translators)
