Jeremiah 41:9-12

9The cistern where Ishmael dumped the bodies of the men he murdered was the large one dug by King Asa when he fortified Mizpah to protect himself against King Baasha of Israel. Ishmael son of Nethaniah filled it with corpses.

10Then Ishmael made captives of the king’s daughters and the other people who had been left under Gedaliah’s care in Mizpah by Nebuzaradan, the captain of the guard. Taking them with him, he started back toward the land of Ammon.

11But when Johanan son of Kareah and the other military leaders heard about Ishmael’s crimes,

12they took all their men and set out to stop him. They caught up with him at the large pool near Gibeon.
