Yirmeyah 41:1-2

Orthodox Jewish Bible

41 Now it came to pass in the seventh month, that Yishmael ben Netanyah ben Elishama, who was zera hameluchah, and the officers of HaMelech, even ten anashim with him, came unto Gedalyah ben Achikam to Mitzpah; and there they did eat lechem together in Mitzpah.

² Then arose Yishmael ben Netanyah, and the ten anashim that were with him, and struck down Gedalyah ben Achikam ben Shaphan with the cherev, and killed him, whom Melech Bavel had made governor over ha’aretz.
