2 Kings 25:22-25

22Then he made Gedaliah the son of Ahikam, the son of Shaphan, governor over the people who remained in the land of Judah, whom Nebuchadnezzar king of Babylon had left.

23Now when all the captains of the armies, they and their men, heard that the king of Babylon had made Gedaliah governor, they came to Gedaliah at Mizpah—Ishmael the son of Nethaniah, Johanan the son of Careah, Seraiah the son of Tanhumeth the Netophathite, and Jaazaniah the son of a Maachathite, they and their men.

24And Gedaliah took an oath before them and their men, and said to them, “Do not be afraid of the servants of the Chaldeans. Dwell in the land and serve the king of Babylon, and it shall be well with you.”

25But it happened in the seventh month that Ishmael the son of Nethaniah, the son of Elishama, of the royal family, came with ten men and struck and killed Gedaliah, the Jews, as well as the Chaldeans who were with him at Mizpah.
