Some of Judah's army officers and their men were still in the open country. They heard that the king of Babylonia had appointed Gedaliah, the son of Ahikam, as governor over Judah. He had put him in charge of the men, women and children who were still there. They were the poorest people in the land. They hadn't been taken to Babylon.
