2 Kings 25:22-25

22Then King Nebuchadnezzar appointed Gedaliah son of Ahikam and grandson of Shaphan as governor over the people he had left in Judah.

23When all the army commanders and their men learned that the king of Babylon had appointed Gedaliah as governor, they went to see him at Mizpah. These included Ishmael son of Nethaniah, Johanan son of Kareah, Seraiah son of Tanhumeth the Netophathite, Jezaniah son of the Maacathite, and all their men.

24Gedaliah vowed to them that the Babylonian officials meant them no harm. “Don’t be afraid of them. Live in the land and serve the king of Babylon, and all will go well for you,” he promised.

25But in midautumn of that year, Ishmael son of Nethaniah and grandson of Elishama, who was a member of the royal family, went to Mizpah with ten men and killed Gedaliah. He also killed all the Judeans and Babylonians who were with him at Mizpah.
