Following are a number of back-translations as well as a sample translation for translators of Jeremiah 23:17:

• Kupsabiny: “They say to those people who refuse to listen to me,
  ‘God has said that you shall get peace.’
  And the rebels, they say to those (people),
  ‘Nothing shall hurt you.’ ’” (Source: Kupsabiny Back Translation)
• Hiligaynon: “This is what they always say to the people who criticize me and follow their flinty/hard heart: ‘Your (plur.) well-being/situation will- surely -become well, says the Lord. No harm will-happen to you (plur.).’” (Source: Hiligaynon Back Translation)
• English: “They habitually say to those who hate me,
  ‘Yahweh says that you will have peace.’
  And they say to those who stubbornly do what they want to do,
  ‘Nothing bad will happen to you because of your doing those things.’” (Source: Translation for Translators)
