Jeremiah 41:2, 10

Then Ishmael the son of Nethaniah, and the ten men who were with him, arose and struck Gedaliah the son of Ahikam, the son of Shaphan, with the sword, and killed him whom the king of Babylon had made governor over the land.

Then Ishmael carried away captive all the rest of the people who were in Mizpah, the king’s daughters and all the people who remained in Mizpah, whom Nebuzaradan the captain of the guard had committed to Gedaliah the son of Ahikam. And Ishmael the son of Nethaniah carried them away captive and departed to go over to the Ammonites.
