Following are a number of back-translations as well as a sample translation for translators of Jeremiah 16:19:

• Kupsabiny: “You are my strength, oh God
  and you are my rock/cave,
  where I flee to when troubles come.
  Communities from every part of the world shall come to you
  and say,
  ‘The forefathers worshipped things of lies/deceit,
  things that do not save a person.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “I said, ‘O LORD, you (sing.) are my strength and firm place-of-refuge in times of difficulty. The nations in the entire world will-come-near to you (sing.), and will-say, ‘The little-gods of our (incl.) ancestors have no value. They did no good at-all for/to them.” (Source: Hiligaynon Back Translation)
