2 Kings 25:23-25

231When all the captains of the forces, they and their men, heard that the king of Babylon had appointed Gedaliah governor, they came to Gedaliah at 2Mizpah, namely, Ishmael the son of Nethaniah, Johanan the son of Kareah, Seraiah the son of Tanhumeth the Netophathite, and Jaazaniah the son of the Maacathite, they and their men. 24And Gedaliah swore to them and their men and said to them, “Do not be afraid of the servants of the Chaldeans; live in the land and serve the king of Babylon, and it will go well for you.”

253But it happened in the seventh month, that Ishmael the son of Nethaniah, the son of Elishama, of the royal 4family, came 5with ten men and struck Gedaliah down so that he died along with the Jews and the Chaldeans who were with him at Mizpah.
