Jeremiah 41:1-5

1Now it was in the seventh month, that Ishmael son of Nethaniah son of Elishama—of royal descent and one of the chief officers of the king, along with ten men—came to Gedaliah son of Ahikam to Mizpah. While they were eating bread there together in Mizpah,

2Ishmael son of Nethaniah rose up with the ten men that were with him and struck down Gedaliah son of Ahikam son of Shaphan with the sword—putting to death the one whom the king of Babylon had appointed over the land.

3Ishmael also slew all the Jews who were with Gedaliah at Mizpah, as well as the Chaldean soldiers who were found there.

4Now it was the next day after he had slain Gedaliah, when no one knew about it,

5that 80 men came from Shechem, from Shiloh, and from Samaria, with their beards shaved off, their clothes rent, and having gashed themselves, with grain offerings and frankincense in their hand to bring to the House of Adonai.
