1 Chronicles 9:17-22

17The gatekeepers were Shallum, Akkub, Talmon, Ahiman, and their kinsmen (Shallum was the chief); 18until then they were in the king’s gate on the east side as the gatekeepers of the camps of the Levites. 19Shallum the son of Kore, son of Ebiasaph, son of Korah, and his kinsmen of his fathers’ house, the Korahites, were in charge of the work of the service, keepers of the thresholds of the tent, as their fathers had been in charge of the camp of the LORD, keepers of the entrance. 20And Phinehas the son of Eleazar was the chief officer over them in time past; the LORD was with him. 21Zechariah the son of Meshelemiah was gatekeeper at the entrance of the tent of meeting. 22All these, who were chosen as gatekeepers at the thresholds, were 212. They were enrolled by genealogies in their villages. David and Samuel the seer established them in their office of trust.
