'Govern' in the Bible

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.

They were afraid of what the Babylonians might do because Ishmael son of Nethaniah had killed Gedaliah son of Ahikam, whom the king of Babylon had appointed to govern the country.
