Following are a number of back-translations as well as a sample translation for translators of Jeremiah 22:10:

• Kupsabiny: “You people of Judah, do not cry for king Josiah,
  or mourn his death.
  But cry for his son
  that one who is being taken far away never to be seen again,
  or/and (never) return to his country where he was born.” (Source: Kupsabiny Back Translation)
• Hiligaynon: “People of Juda, [you (plur.)] do not cry for King Josia who is now dead, but [you (plur.)] cry loudly/(bitterly) for his child Jehoahaz who succeeded him as king of Juda. For he was-taken-captive and he can- not [intensifier] -return. He will- no longer -see again the land of his birth. For the LORD himself has-said that he can- never[intensifier] -return.” (Source: Hiligaynon Back Translation)
• English: “Yahweh also says, ‘Do not mourn for King Josiah;
  do not cry because he has died.
  Instead, mourn for King Jehoahaz, his son,
  because he will be captured and taken to another country,
  and he will never return to see his own country, Judah, again.’” (Source: Translation for Translators)
