Jeremiah 41:12-16

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.

Then Johanan the son of Kareah and all the commanders of the forces that were with him took from Mizpah all the remnant of the people whom he had recovered from Ishmael the son of Nethaniah, after he had struck and killed Gedaliah the son of Ahikam, that is, the men who were soldiers, the women, the children, and the high officials, whom he had brought back from Gibeon.
