Following are a number of back-translations as well as a sample translation for translators of Jeremiah 8:8:

• Kupsabiny: “How can you (plur.) say,
  ‘We are wise and we have taken hold of the law of God,’
  and yet the writers have bent my laws?” (Source: Kupsabiny Back Translation)
• Hiligaynon: “How can you say that you are wise, is-it because you know the law of the LORD? That the truth is, this was redo/change by your teachers?” (Source: Hiligaynon Back Translation)
• English: “Your men who teach you the laws that Moses wrote have been saying false things about those laws.
  So, why do they continue saying, ‘We are very wise because we have the laws of Yahweh’?” (Source: Translation for Translators)
