Following are a number of back-translations as well as a sample translation for translators of Jeremiah 2:30:

• Kupsabiny: “I punished you and you did not hear.
  You refused for me to draw you back.
  You fought against yourselves killing your prophets
  like a lion tears people into pieces.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “I have-punished your (plur.) children, but it did no good to them. They do not want to-be-taught. You (plur.) yourselves have-killed your (plur.) prophets, like how a hungry lion killed its victim.” (Source: Hiligaynon Back Translation)
• English: “I punished some of you,
  but you did not learn anything from my doing that.
  You have killed many of the prophets that I sent to you,
  like fierce lions kill other animals.” (Source: Translation for Translators)
