Following are a number of back-translations as well as a sample translation for translators of Jeremiah 51:50:

• Kupsabiny: “But oh my people who have escaped death,
  get up right away and leave.
  Even though you are far away from home.
  think about/remember me your God and Jerusalem.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “‘You (plur.) who were left alive, [you (plur.)] flee now from Babilonia and do- not -be-stopping-(here-and-there)! Remember the LORD and Jerusalem even if you are there in the far place.” (Source: Hiligaynon Back Translation)
