Jeremiah 40:11

40:11 Moreover, all the Judeans who were in Moab, Ammon, Edom, and all the other countries heard what had happened. They heard that the king of Babylon had allowed some people to stay in Judah and that he had appointed Gedaliah, the son of Ahikam and grandson of Shaphan, to govern them.

41:2 Ishmael son of Nethaniah and the ten men who were with him stood up, pulled out their swords, and killed Gedaliah, the son of Ahikam and grandson of Shaphan. Thus Ishmael killed the man that the king of Babylon had appointed to govern the country.
