1 Chronicles 9:22-26

Those who were chosen to be gatekeepers at the thresholds were 212 in all. They were registered by genealogy in their settlements, those whom David and Samuel the seer appointed in their official capacity.

So they and their sons were in charge of the gates of the house of the Lord, the house of the tent, in their divisions of service.

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

Their relatives in their settlements were to come in every seven days from time to time to be with them;

for the four chief gatekeepers, who were Levites, served in an official capacity, and were in charge of the chambers and in charge of the treasuries in the house of God.
