2 Kings 25:22-25

22Nebuchadnezzar king of Babylon appointed Gedaliah son of Ahikam, the son of Shaphan, over the people he had left behind in the land of Judah.

23When all the commanders of the armies and their men heard that the king of Babylon had appointed Gedaliah as governor, they came to Gedaliah at Mizpah—Ishmael son of Nethaniah, Johanan son of Kareah, Seraiah son of Tanhumeth the Netophathite, and Jaazaniah1 son of the Maacathite, as well as their men. 24And Gedaliah took an oath before them and their men, assuring them, “Do not be afraid of the servants of the Chaldeans. Live in the land and serve the king of Babylon, and it will be well with you.”

25In the seventh month, however, Ishmael son of Nethaniah, the son of Elishama, who was a member of the royal family, came with ten men and struck down and killed Gedaliah, along with the Judeans and Chaldeans who were with him at Mizpah.
