'Captain of the Guard' in the Bible

If thou canst not be content to dwell alone, then remain with Gedaliah the son of Ahikam, the son of Shaphan: whom the king of Babylon hath made governor over the cities of Judah, and dwell with him among the people, or remain wheresoever it pleaseth thee." So the chief Captain of the guard gave him his expenses with a reward, and let him go.
