1 Chronicles 9:22-24

22All these who were chosen to be porters in the gates were two hundred and twelve. These were reckoned by their genealogy in their villages, whom David and Samuel the seer ordained in their charge.12 23So they and their children had the oversight of the gates of the house of the LORD, namely, the house of the tabernacle, by watch. 24In four quarters were the porters, toward the east, west, north, and south.
