Following are a number of back-translations as well as a sample translation for translators of Jeremiah 30:10:

• Kupsabiny: “Therefore, do not be afraid oh, my people, the stomach of Jacob.
  Do not be afraid oh, house of Israel.
  I will rescue you from that far country,
  your descendants shall come from that land you are prisoners in.
  You shall be living in peace,
  where not one shall frighten you.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “‘So do not be afraid or dismayed/terrified, you (plur.) the descendants of Jacob my servant. I, the LORD, am-saying that I will- surely -get you (from) there at the far place where you have-been-taken-captive. Then you will-live in peace. You no longer will be harmed/[Lit. Not now you will-what(ever)] and no one/nothing will-make you afraid.” (Source: Hiligaynon Back Translation)
• English: “So, you people of Israel who serve me,
  do not be dismayed/worried now,
  because some day I will bring you back from distant places;
  I will bring your descendants back home from the land to which they were exiled.
  Then you Israeli people will again live peacefully and safely,
  and there will not be any nation that will cause you to be terrified.” (Source: Translation for Translators)
