Jeremiah 41:9-12

9Now the cistern where he threw all the bodies of the men he had killed along with Gedaliah was the one King Asa had made as part of his defense against Baasha king of Israel. Ishmael son of Nethaniah filled it with the dead.

10Ishmael made captives of all the rest of the people who were in Mizpah—the king’s daughters along with all the others who were left there, over whom Nebuzaradan commander of the imperial guard had appointed Gedaliah son of Ahikam. Ishmael son of Nethaniah took them captive and set out to cross over to the Ammonites.

11When Johanan son of Kareah and all the army officers who were with him heard about all the crimes Ishmael son of Nethaniah had committed,

12they took all their men and went to fight Ishmael son of Nethaniah. They caught up with him near the great pool in Gibeon.
