Following are a number of back-translations as well as a sample translation for translators of Jeremiah 13:16:

• Kupsabiny: “Exalt your God
  before he sends darkness to you,
  so that you stumble on the hill,
  before he turns the light
  that you have been waiting for
  to become darkness that completely covers you.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “You (plur.) honor the LORD your (plur.) God while he still did not send the darkness, and while you (plur.) still did not stumble on the dark mountains. The light that you (plur.) hope-for he will-make into a terrible/extreme darkness.” (Source: Hiligaynon Back Translation)
