Following are a number of back-translations as well as a sample translation for translators of Jeremiah 15:18:

• Kupsabiny: “Why does my suffering not end
  and my wound goes on without healing?
  You mislead me for sure like a well/hole of water
  that dries up when the land becomes dry.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “Why is my pain without end? Why is my wound could- not -be-healed anymore? Is-this can- not -be-cured? Will you (sing.) disappoint me like a stream that dries on dry-season?’” (Source: Hiligaynon Back Translation)
