Following are a number of back-translations as well as a sample translation for translators of Zephaniah 1:12:

• Kupsabiny: “In those days I shall shine a light in the dark area of Jerusalem searching for people who concentrate on sinful matters who are saying, ‘God does not bless/reward people or punish people.’” (Source: Kupsabiny Back Translation)
• Newari: “q1 At that time I will search Jerusalem with a lamp,
  and I will punish those who are complacent
  who settle like dregs in wine,
  and who think ‘the LORD will do nothing,
  either good or bad.’” (Source: Newari Back Translation)
• Hiligaynon: “‘At that time (lso I will-search carefully the ones- (who)-come-from-Jerusalem and I will-punish the people who are- just -taking-it-easy/relaxing who say to themselves, ‘The LORD will- not -do either good or bad.’” (Source: Hiligaynon Back Translation)
