Following are a number of back-translations as well as a sample translation for translators of Jeremiah 2:19:

• Kupsabiny: “You will be punished for your sins
  and condemned because you removed yourselves from me.
  You will see/realize that (it is) very bad,
  when/if you abandon your God whom you do not honor.
  I the God of power have spoken.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “Because of your (plur.) wickedness and turning-away from me, I will-punish you (plur.). [You (plur.)] think well/[lit. good] of how bad and bitter is your (plur.) rejecting and not honoring the LORD your (plur.) God. I, the Lord GOD who-is Almighty, (am) the-(one) saying this.” (Source: Hiligaynon Back Translation)
