1 Chronicles 9:22-24

22Altogether, those chosen to be gatekeepers at the thresholds numbered 212. They were registered by genealogy in their villages. The gatekeepers had been assigned to their positions of trust by David and Samuel the seer.

23They and their descendants were in charge of guarding the gates of the house of the Lord—the house called the tent of meeting.

24The gatekeepers were on the four sides: east, west, north and south.
