AT: "Jehoiachin is as useless as a broken vessel and no one is happy with him." (See: [[rc://en/ta/man/translate/figs-metaphor]] and [[rc://en/ta/man/translate/figs-rquestion]])
# Why have they thrown him and his descendants out, and have poured them out into a land that they did not know?
This rhetorical question explains what will happen to the worthless Jehoiachin. AT: "Therefore the enemy will remove Jehoiachin and his family from the land and take them to a foreign land." (See: [[rc://en/ta/man/translate/figs-rquestion]])
