2 Kings 25:23, 25

The army captains and their men heard that the king of Babylon had made Gedaliah governor, so they came to Gedaliah at Mizpah. They were Ishmael son of Nethaniah, Johanan son of Kareah, Seraiah son of Tanhumeth the Netophathite, Jaazaniah son of the Maacathite, and their men.

In the seventh month Ishmael son of Nethaniah, son of Elishama from the king’s family, came with ten men and killed Gedaliah. They also killed the men of Judah and Babylon who were with Gedaliah at Mizpah.
