Following are a number of back-translations as well as a sample translation for translators of Jeremiah 15:7:

• Kupsabiny: “I have sifted you there at the gate of every city
  of this land.
  I have crushed you my people,
  killed all your children
  because you did not abandon your bad ways.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “I will-punish you (plur.) as-if-like chaff that is winnowed at the gates/entrance of the city. I will-destroy you (plur.) and your (plur.) children, because you (plur.) did- not -turn-away from your (plur.) wicked ways.” (Source: Hiligaynon Back Translation)
• English: “At the gates of your cities, I will scatter you like a farmer scatters the chaff from his grain by winnowing it/throwing it up to allow the wind to blow the chaff away.
  You, my people, have refused to turn away from your evil behavior.
  So, I will get rid of you,
  and I will even cause your children to be killed.” (Source: Translation for Translators)
