Jeremiah 41:2, 10

Ishmael son of Nethaniah and the ten men who were with him got up and struck down Gedaliah son of Ahikam, the son of Shaphan, with the sword, killing the one whom the king of Babylon had appointed as governor over the land.

Ishmael made captives of all the rest of the people who were in Mizpah—the king’s daughters along with all the others who were left there, over whom Nebuzaradan commander of the imperial guard had appointed Gedaliah son of Ahikam. Ishmael son of Nethaniah took them captive and set out to cross over to the Ammonites.
