Jeremiah 41:11-15

But Johanan the son of Kareah and all the commanders of the forces that were with him heard about all the evil that Ishmael the son of Nethaniah had done.

So they took all the men and went to fight with Ishmael the son of Nethaniah and they found him by the large pool that is in Gibeon.

Now as soon as all the people who were with Ishmael saw Johanan the son of Kareah and all the commanders of the forces that were with him, they were joyful.

So all the people whom Ishmael had taken captive from Mizpah turned around and came back, and went to Johanan the son of Kareah.

But Ishmael the son of Nethaniah escaped from Johanan with eight men, and went to the sons of Ammon.
