Jeremiah 41:9-12

9Now the cistern where Ishmael cast all the corpses of the men whom he killed, because they were on Gedaliah’s side, was the one which King Asa had made for fear of King Baasa of Israel. Ishmael son of Nethaniah filled it with the slain.

10Then Ishmael carried away captive all the rest of the people that were in Mizpah, including the king’s daughters—all the people who were left in Mizpah over whom Nebuzaradan the captain of the guard had put under the charge of Gedaliah son of Ahikam. Ishmael son of Nethaniah carried them away captive, and set off to cross over to Ammon’s children.

11But Johanan son of Kareah, and all the commanders of the forces that were with him heard about all the evil that Ishmael son of Nethaniah had done.

12So they took all the men and went to fight with Ishmael son of Nethaniah, and found him by the great pool in Gibeon.
