Jeremiah 41:1-2

In September-October, not long after the fall of Jerusalem, Ishmael and 10 other men came to Mizpah and ate a meal with Gedaliah. It is impossible to date this event by year, but most authorities believe it happened quite soon after the fall of Jerusalem (cf. 2 Kings 25:22-26). During the meal, they got up and murdered Nebuchadnezzar’s appointee with the sword. [Note: Jews in the postexilic period commemorated this event with a yearly fast (Zechariah 7:5; 8:19).] This was not only an act of treason, but a violation of ancient Near Eastern hospitality customs.
