2 Kings 25:24-26
25:24 Gedaliah took an oath so as to give them and their troops some assurance of safety. He said, “You don’t need to be afraid to submit to the Babylonian officials. Settle down in the land and submit to the king of Babylon. Then things will go well for you.”
25:25 But in the seventh month Ishmael son of Nethaniah, son of Elishama, who was a member of the royal family, came with ten of his men and murdered Gedaliah, as well as the Judeans and Babylonians who were with him at Mizpah.
25:26 Then all the people, from the youngest to the oldest, as well as the army officers, left for Egypt, because they were afraid of what the Babylonians might do.
