1 Chronicles 9:17-22

The gatekeepers: Shallum, Akkub, Talmon, Ahiman and their fellow Levites, Shallum their chief being stationed at the King’s Gate on the east, up to the present time. These were the gatekeepers belonging to the camp of the Levites. Shallum 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. In earlier times Phinehas son of Eleazar was the official in charge of the gatekeepers, and the LORD was with him. Zechariah son of Meshelemiah was the gatekeeper at the entrance to the tent of meeting. Altogether, 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.
