Following are a number of back-translations as well as a sample translation for translators of Ecclesiastes 5:12:

• Kupsabiny: “The person who is working hard sleeps very nicely and that is whether he is satisfied, or lacks food. But a rich person sleeps badly until morning since he is thinking/worrying about his things.” (Source: Kupsabiny Back Translation)
• Newari: “The laborer will sleep soundly, whether he eats much or little.
  But the wealthy one will not fall asleep because he has so much wealth and property.” (Source: Newari Back Translation)
• Hiligaynon: “A worker can-sleep well even his food is little or plenty, but a wealthy on-the-other-hand, for too much wealth, can- not -sleep well.” (Source: Hiligaynon Back Translation)
