Following are a number of back-translations as well as a sample translation for translators of Jeremiah 22:21:

• Kupsabiny: “I spoke to you (plur.) to be on guard when you were safe/supported
  but you said at that time,
  ‘We have not heard what you are saying.’
  These were your customs from childhood
  you did not obey what I God am saying.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “I warned you (plur.) when your (plur.) situation was still well, but you (plur.) would not listen. That is already your (plur.) character when you (plur.) were still young; you (plur.) would not obey me.” (Source: Hiligaynon Back Translation)
• English: “When you were prosperous, I warned you,
  but you replied, ‘We will not pay attention to what you say.’
  You have been acting like that since you were young;
  you have never obeyed me.” (Source: Translation for Translators)
