Following are a number of back-translations as well as a sample translation for translators of Jeremiah 13:27:

• Kupsabiny: “I have seen the greed of adultery
  and you have become a rotten/smelly prostitute.
  I have also seen the despicable things you are doing
  there in the bush and the open field.
  How bad it is for you, oh Jerusalem!
  For how long will you stay dirty like that?’” (Source: Kupsabiny Back Translation)
• Hiligaynon: “I see your (plur.) dreadful deeds which is the worshipping of little-gods on the mountains and in the farms. You (plur.) are like a woman who-committed-adultery-with-a-man who has great lust, or like a shameful woman who sells her body. You (plur.) are-to-be-pitied, who-come-from-Jerusalem! Until when will- you (plur.) -remain dirty/unclean?” (Source: Hiligaynon Back Translation)
