Jeremiah 41:2, 10

Ishmael and his ten men suddenly jumped up, drew their swords, and killed Gedaliah, whom the king of Babylon had appointed governor.

Then Ishmael made captives of the king’s daughters and the other people who had been left under Gedaliah’s care in Mizpah by Nebuzaradan, the captain of the guard. Taking them with him, he started back toward the land of Ammon.
