Then send them out

This seems to mean that Jeremiah was to send a set of fetters and yoke to each king listed. But some versions of the Bible translate this as "Then send out messages."

Send them by the hand of those kings' ambassadors who ... Judah

The hand is a synecdoche for the person. Alternate translation: "Have those kings' ambassadors, who ... Judah, take them" (See: rc://en/ta/man/jit/figs-synecdoche)
