No, I meant at the time of the Babylonian captivity. Sorry for the sentence structure. The Babylonians released Jeremiah in the captivity and told him he could go where he wished. He went to Mizpah where there were a few Judaeans (including the daughters) under a Jewish government that didn't go into captivity. Jeremiah plead with them not to run to Egypt, but they did, fearing the Babylonians. There they all died, except for a remnant. That remnant went to Ireland.
Oops. They actually feared the Ammonites. An small Ammonite force killed the governer and a few others appointed by the Babylonians to govern Mizpah. They took most of the rest hostage, and then were rescued on the way to Ammonite captivity by Johanan (a Judaean captain of the fields), returned to Chimham (by Bethlehem), and then went to Egypt.
