2 Kings 25:25-26

But 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. Then all the people of Judah, from the least to the greatest, as well as the army commanders, fled in panic to Egypt, for they were afraid of what the Babylonians would do to them.
