1 Chronicles 9:19-26

19Shallum son of Kore, the son of Ebiasaph, the son of Korah, and his fellow gatekeepers from his family (the Korahites) were responsible for guarding the thresholds of the tent just as their ancestors had been responsible for guarding the entrance to the dwelling of the Lord. 20In earlier times Phinehas son of Eleazar was the official in charge of the gatekeepers, and the Lord was with him. 21Zechariah son of Meshelemiah was the gatekeeper at the entrance to the tent of meeting. 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. 25Their fellow Levites in their villages had to come from time to time and share their duties for seven-day periods. 26But the four principal gatekeepers, who were Levites, were entrusted with the responsibility for the rooms and treasuries in the house of God.
