Jeremiah 41:1-3

1In the seventh month, Ishmael son of Nethaniah, son of Elishama, of the royal family and one of the king’s chief officers, came with ten men to Gedaliah son of Ahikam at Mizpah. They ate a meal together there in Mizpah,

2but then Ishmael son of Nethaniah and the ten men who were with him got up and struck down Gedaliah son of Ahikam, son of Shaphan, with the sword; he killed the one the king of Babylon had appointed in the land.

3Ishmael also struck down all the Judeans who were with Gedaliah at Mizpah, as well as the Chaldean soldiers who were there.
