Jeremiah 41:9-12

41:9 Now the cistern where Ishmael threw all the dead bodies of those he had killed was a large one that King Asa had constructed as part of his defenses against King Baasha of Israel. Ishmael son of Nethaniah filled it with dead bodies. 41:10 Then Ishmael took captive all the people who were still left alive in Mizpah. This included the royal princesses and all the rest of the people in Mizpah that Nebuzaradan, the captain of the royal guard, had put under the authority of Gedaliah son of Ahikam. Ishmael son of Nethaniah took all these people captive and set out to cross over to the Ammonites.
