Jeremiah 41:2
Then arose Ishmael the son of Nethaniah, and the ten men that were with him, and smote Gedaliah the son of Ahikam the son of Shaphan with the sword, and slew him, whom the king of Babylon had made governor over the land. Then arose Ishmael the son of Nethaniah, and the ten men that were with him, and smote Gedaliah the son of Ahikam the son of Shaphan with the sword, and slew him, whom the king of Babylon had made governor over the land.
Jeremiah 41:2 records the treacherous killing of Gedaliah by the sword at the hands of Ishmael son of Nethaniah and the ten men with him. Gedaliah was the man whom the king of Babylon had appointed governor over the land. His death left the poor remnant of Judah without its governor. After further trials following that loss, the leaders of the remnant persuaded the people to flee to Egypt, despite Jeremiah's warning not to go.
