Following are a number of back-translations as well as a sample translation for translators of Jeremiah 5:5:

• Kupsabiny: “I shall confront the leaders
  to tell them these words/matters.
  Truly they do know the wishes/demands of God
  and what their God wants for them to do.’
  But they all refused the power/authority of God
  or/and to obey him.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “Therefore I will-go to their leaders/[lit. heads] and speak to them. Surely they know the ways of the LORD their God which being-caused-to-be-followed by them.’ But even they also rejected what is-being-to-be-followed by God.” (Source: Hiligaynon Back Translation)
