2 Kings 25:25-26

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. Then all the people, from the least important to the most important, along with the army leaders, ran away to Egypt, because they were afraid of the Babylonians.
